Does God Exist? A Christian Argument from Non-biblical Sources

Probe founder, Jimmy Williams, looks at evidence for the existence of God from multiple, non-biblical sources.  He demonstrates that God’s creation speaks to his creator.  The important apologetic discussion forms the foundation for a complete biblical understanding of God and His purposes.

Metaphysical Options

Most will agree that the most basic, fundamental question concerning existence is not that nothing is here, but rather that something is here. I am a part of some kind of reality. I possess a consciousness, an awareness that something is transpiring, unfolding, happening. And you and I are part of it. The reality borne out of our personal observation and experience is that we are participants in a space-time universe which is characterized by a series of events. The mind naturally asks the question, “What is it?” Where did it come from?” Did the cosmos, what we see, simply come into being from nothing, or has this material universe of which we are a part always been here? Or is something or someone which transcends this material universe responsible for bringing it into existence and us with it?

All of these questions relate to the philosophical concept of metaphysics. Webster defines it thusly: “That division of philosophy which includes ontology, or the science of being and cosmology, or the science of fundamental causes and processes in things.”{1} When we seek to answer these basic questions, then, we are thinking “metaphysically” about the origin and the causes of the present reality. And at this basic, fundamental level of consideration we really are left with few options, or possible answers, to account for or explain the universe. The three potential candidates are:

(1) Something came from nothing. Most reject this view, since the very idea defies rationality. This explanation to account for the universe is not widely held. Kenny remarks: “According to the big bang theory, the whole matter of the universe began to exist at a particular time in the remote past. A proponent of such a theory, . . . if he is an atheist, must believe that the matter of the universe came from nothing and by nothing.”{2} Since nothing cannot produce something by rules of logic (observation, causality), something is eternal and necessary. Since any series of events is not eternal (thus a contradiction), there is, therefore, an eternal, necessary something not identical to the space-time universe.

(2) Matter is eternal and capable of producing the present reality through blind chance. Carl Sagan stated this view clearly when he said, “All that ever was, all that is, and all that ever shall be is the Cosmos.”{3} This second view has spawned two basic worldviews-Materialism (or Naturalism) and Pantheism. Both hold the premise that nothing exists beyond matter. Materialism therefore is atheistic by definition. Pantheism is similar but insists that since God does not exist, nature is imbued with “god” in all its parts.

(3) God created the universe. This view, Theism, holds forth the assertion that Someone both transcends, and did create the material universe of which we are a part. There are no other logical alternatives to explain the cosmos. Christians, of course, embrace this third view, along with all other theists, as the most reasonable explanation for what we find to be true of ourselves and of the world. Holding this view is not simply a statement of blind faith. There are sound and rational reasons for preferring this view over the other two. Theism is therefore a reasonable idea. In fact it is more reasonable to believe that God exists than not to believe He exists. Theologians have posed several lines of “proof” to argue for God’s existence. These arguments, while not proving the existence of God, do nevertheless provide insights that may be used to show evidence of His existence.

The Cosmological Argument

This argument centers around the concept of causality. Every event has a cause, and that includes the universe. It had a beginning. There was a time when it was not, and a time when it was:

An infinite number of real parts of time, passing in succession and exhausted one after another, appears so evident a contradiction that no man, one should think, whose judgment is not corrupted, instead of being improved, by the sciences, would ever be able to admit it.” (emphasis mine){4}

Hume is here arguing that time and space are not infinite, not eternal. If this is true, the universe, which is an “effect,” had a cause. Robert Jastrow comments,

“The most complete study made thus far has been carried out . . .by Allan Sandage. He compiled information on 42 galaxies, ranging out in space as far as six billion light years from us. His measurements indicate that the universe was expanding more rapidly in the past than it is today. This result lends further support to the belief that the universe exploded into being.”{5}

He goes on to say:

“No explanation other than the big bang has been found for the fireball radiation. The clincher, which has convinced almost the last doubting Thomas, is that the radiation discovered by Penzias and Wilson has exactly the pattern of wavelengths expected for the light and heat produces in a great explosion.”{6}

Jastrow also concludes the universe is dying:

“Once hydrogen has been burned within that star and converted to heavier elements, it can never be restored to its original state. Minute by minute and year by year, as hydrogen is used up in stars, the supply of this element in the universe grows smaller.”{7} “Astronomers now find they have painted themselves into a corner because they have proven, by their own methods, that the world began abruptly in an act of creation to which you can trace the seeds of every star, every planet, every thing in this cosmos and on the earth. And they have found that all this happened as a product of forces they cannot hope to discover.”{8}

Some have argued that an infinite regress of causes may not be logically possible. They say the universe is not a “whole” that needs a single cause, but rather that it is “mutually dependent” upon itself! Mutual dependence misses the point. The real issue is why there is an existing universe rather than a non-existing one. Reality and rationality suggest that every event has a cause. Whole series of events must have a cause as well (since the whole is the sum of the parts). If all the parts were taken away, would there be anything left? If we say yes, then God exists (i.e. an eternal necessary being that is more than the world. If we say no, then the whole is contingent too, and needs a cause beyond it (God).

We will conclude this section with an examination of perhaps the most often-asked question concerning the cosmological argument, “Where did God come from?” While it is both reasonable and legitimate to ask this question of the universe which we have just examined, it is irrational and nonsensical to ask that same question of God, since it implies to Him characteristics found only in the finite universe: space and time. By definition, something eternal must exist outside this space/time continuum. The very question posed reveals the inquirer’s fallacy of reasoning from within his own space/time context! By definition, something eternal must exist outside both time and space. God has no beginning; He IS! (Exodus 3:14).

The Teleological Argument

This second argument for the existence of God addresses the order, complexity, and diversity of the cosmos. “Teleological” comes from the Greek word “telos,” which means “end” or “goal.” The idea behind the argument is that the observable order in the universe demonstrates that it functions according to an intelligent design, something undeniable to an open-minded, intelligent being. The classic expression of this argument is William Paley’s analogy of the watchmaker in his book Evidences. If we were walking on the beach and found a watch in the sand, we would not assume that it washed up on the shore having been formed through the natural processes and motions of the sea. We would rather naturally assume that it had been lost by its owner and that somewhere there was a watchmaker who originally designed and built it with a specific purpose in mind. Intelligence cannot be produced by non-intelligence any more than nothing can produce something. There is, therefore, an eternal, necessary intelligence present and reflected in the space-time universe.

Until about five hundred years ago, humanity had no difficulty in acknowledging God as the Creator of the natural order. The best explanation saw Him as the divine Designer who created it with a purpose and maintained all things by the word of His power (Hebrews 1:3; Colossians 1:17). But the rise of modern science initiated a process we could call the “demythologizing of nature,” the material world. Superstition and ignorance had ascribed spirit life even to forest, brook, and mountain. Things not understood scientifically were routinely accepted to be unexplained, supernatural forces at work. Slowly, the mysterious, spiritual factor was drained away as scholars and scientists replaced it with natural explanations and theories of how and why things actually worked. After Copernicus, human significance diminished in the vastness of the cosmos, and it was felt only time and research, not God, would be needed to finally explain with accuracy the totality of the natural order. The idea of a transcendent One came to be deemed unnecessary, having been invalidated by the new theory of natural selection.

Ironically, the same science which took God away then, is bringing back the possibility of His existence today. Physics and quantum mechanics have now brought us to the edge of physicality, to a place where sub-atomic particle structures are described by some as spirit, ghost-like in quality. Neuro-physiologists grapple with enigmatic observations suggesting that the mind transcends the brain! Psychology has developed an entirely new branch of study (parapsychology) which asserts that psycho-spiritual forces (ESP, biofeedback, etc.) actually function beyond the physical realm. Molecular biologists and geneticists, faced with the highly-ordered and complex structures of DNA, ascribe a word implying “intelligence” to the chaining sequences: the genetic “code.” And we have already concluded that astrophysicists have settled on the “big bang” which seems to contradict the idea that matter is eternal, and, huge as it is, the universe appears to be finite. Whether we look through the microscope or the telescope it becomes more difficult in the light of experimental science to hold to the old premise that such order and complexity are the products of blind chance. The old naturalistic assumptions are being critically reexamined, challenged, and found to be unconvincing by many of today’s scientists. Dr. Walter Bradley, Professor Emeritus of Mechanical Engineering at Texas A & M University states the case:

“Discoveries of the last half of the 20th century have brought the scientific community to the realization that our universe and our planet in the universe are so remarkably unique that it is almost impossible to imagine how this could have happened accidentally, causing may agnostic scientists to concede that indeed some intelligent creative force may be required to account for it.”{9}

Areas of reconsideration include cosmology and the origin of life, essential elements of design and their recognition, the minimal requirements for a universe to support both life of any type and specifically complex human life, why these requirements are met in our universe, and requirements for a place in that universe uniquely met by planet earth. All of these remarkable features of our world are being reevaluated and point toward intelligent design.

The Moral Argument

This argument for God’s existence is based on the recognition of humankind’s universal and inherent sense of right and wrong. (cf. Romans 2:14,15). No culture is without standards of behavior. All groups recognize honesty as a virtue along with wisdom, courage, and justice. And even in the most remote jungle tribes, murder, rape, lying, and theft are recognized as being wrong, in all places and at all times. The question arises, “Where does this sense of morality come from?” C. S. Lewis speaks of this early on in his classic work Mere Christianity. He calls this moral law “The Rule of Right and Wrong”–“a thing that is really there, not made up by ourselves.”{10} For years Lewis struggled against God because the universe to him seemed unjust and cruel. But he began to analyze his outrage. Where did he get the very ideas of just and unjust? He said, “A man does not call a line crooked unless he has some idea of a straight line.”{11}

He goes on to suggest that there are three parts to morality. Using the analogy of a fleet of ships on a voyage, he points out that three things can go wrong. The first is that ships may either drift apart or collide with and do damage to one another (alienation, isolation: people abusing, cheating, bullying one another). The second is that individual ships must be seaworthy and avoid internal, mechanical breakdown (moral deterioration within an individual). Lewis goes on to point out that if the ships keep having collisions they will not remain seaworthy very long, and of course, it their steering parts are out of order, they will not be able to avoid collisions! But there is a third factor not yet taken into account, and that is, “Where is the fleet of ships headed?” The voyage would be a failure if it were meant to reach New York but actually arrived in Buenos Aires (the general purpose of human life as a whole, what man was made for)!{12}

The human conscience to which Paul refers in Romans 2 is not found in any other animal–only man. The utter uniqueness of this moral compass within humans, along with other exclusively human qualities (rationality, language, worship and aesthetic inclinations) strongly suggest that man not only has a relationship downward to animals, plants and earth, but also a relationship upward to the God in Whose image he is. As we saw God’s great power and intelligence expressed in the first two arguments, we also see here that this sense of morality, not known in the world of nature, comes from the Great Law Giver Who is Himself in character the “straight line” (righteous, just, holy) against which all human actions are measured.

A Word about Atheism and Agnosticism

An atheist is a person who makes a bold assertion, “There is no God.” It is bold because it claims in an absolute manner what we have stated above what is not possible: i.e., the existence or non-existence of God cannot be proven absolutely. It is also bold because, in order to make such an assertion, an atheist would literally have to be God himself! He would need to possess the qualities and capabilities to travel the entire universe and examine every nook and cranny of it before he would ever qualify to hold such a dogmatic conclusion!

The most brilliant, highly-educated, widely-traveled human on earth today, having maximized his/her brain cells to optimum learning levels for a lifetime could not possibly “know” 1/1000th of all that could be known. And knowledge is now doubling by the years rather than by the decades or centuries of the past! Is it possible that God could still exist outside the very limited, personal knowledge/experience of one highly intelligent human being? Furthermore, before an atheist can identify himself as one, he must first acknowledge the very idea, or concept, or possibility of God so he can then deny His existence!

The Bible says that “he who comes to God must believe that He is. . .” (Hebrews 11:6). In other words, there is a “faith” factor relative to a belief in God’s existence. But the dogmatic and bold assertion above is itself an expression of faith. It takes faith to believe God is, and it takes faith to say God is not. In my judgment, it takes even more faith for the atheist to believe in his position because he holds to his faith against overwhelming evidence to the contrary. Christians also affirm God’s existence on the basis of faith, but it is a reasonable faith based on the true nature of the cosmos, not a blind faith.

Turning to agnosticism, Webster defines it as a position which states that “neither the existence nor the nature of God, nor the ultimate origin of the universe is known or knowable.”{13} Here again is a bold statement: When the agnostic says, “I don’t know,” what is really implied is “I can’t know, you can’t know, and nobody can know.” Leith Samuel in his little book Impossibility of Agnosticism, mentions three kinds of agnostics: {14}

Dogmatic: “I don’t know, you don’t know, and no one can know.” Here is a person who already has his mind made up. He has the same problems as the atheist above–he must know everything in order to hold this position honestly.

Indifferent: “I don’t know and I don’t care.” It is not likely that God would reveal Himself to someone who does not care to know: “He who has ears, let him hear.” (Luke 14:35).

Dissatisfied: “I don’t know, but I would like to know.” Here is a person who demonstrates an openness to truth and a willingness to change his position should he have sufficient reasons. If such were the case, he would also be demonstrating what is true of agnosticism, namely, that it is meant to be a temporary path in search of truth which gives way to a more reasonable and less skeptical view of life and all reality.

“For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so they are without excuse.” (Saint Paul, Romans 1:20).

“Only the fool has said in his heart, ‘There is no God.’ ” (King David, Psalm 14:1).

Evidence for God’s Existence

Romans chapter 1 says that God has planted evidence of Himself throughout His creation so we are without excuse. Sue Bohlin looks at different types of evidence indicating that God really does exist.

A “Just Right” Universe

There’s so much about the universe, and our world in particular, that we take for granted because it works so well. But Christian astronomer Dr. Hugh Ross has cited twenty-six different characteristics about the universe that enable it to sustain life. And there are thirty-three characteristics about our galaxy, our solar system, and the planet Earth that are finely-tuned to allow life to exist.{1} I do well to make the meat, potatoes, vegetables, and bread all come out at the same time for dinner; we’re talking about fifty-nine different aspects all being kept in perfect balance so the universe hangs together and we can live in it!

Our Earth, for instance, is perfectly designed for life. It’s the “just right” size for the atmosphere we need. Its size and corresponding gravity hold a thin, but not too thin, layer of gases to protect us and allow us to breathe. When astronaut John Glenn returned to space, one of the things that struck him was how thin and fragile our atmosphere is (only 50 miles above the Earth). If our planet were smaller it couldn’t support an atmosphere, like on Mercury. If it were larger, like Jupiter, the atmosphere would contain free hydrogen, which is poison for us.{2} Earth is the only planet we know of that contains an atmosphere that can support human, animal, and plant life.

The Earth is also placed at a “just right” distance from the sun and the other planets in our solar system. If we were closer to the sun, we’d burn up. If we were farther away, we’d freeze. Because Earth’s orbit is nearly circular, this slightly elliptical shape means that we enjoy a quite narrow range of temperatures, which is important to life. The speed of Earth’s rotation on its axis, completing one turn every 24 hours, means that the sun warms the planet evenly. Compare our world to the moon, where there are incredible temperature variations because it lacks sufficient atmosphere or water to retain or deflect the sun’s energy.

Speaking of the moon, its important that there is only one moon, not two or three or none, and it’s the “just right” size and distance from us. The moon’s gravity impacts the movement of ocean currents, keeping the water from becoming stagnant.{3}

Water itself is an important part of a “just right” world. Plants, animals and human beings are mostly made of water, and we need it to live. One of the things that makes Earth unique is the abundance of water in a liquid state.

Water has surface tension. This means that water can move upward, against gravity, to bring liquid nutrients to the tops of the tallest plants.

Everything else in the world freezes from the bottom up, but water freezes from the top down. Everything else contracts when it freezes, but water expands. This means that in winter, ponds and rivers and lakes can freeze at the surface, but allow fish and other marine creatures to live down below.

The fact that we live on a “just right” planet in a “just right” universe is evidence that it all was created by a loving God.

The Nagging Itch of “Ought”

As a mother, I was convinced of the existence of a moral God when my children, without being taught, would complain that something wasn’t “fair.” Fair? Who taught them about fair? Why is it that no one ever has to teach children about fairness, but all parents hear the universal wail of “That’s not fa-a-a-a-a-air!” The concept of fairness is about an internal awareness that there’s a certain way that things ought to be. It’s not limited to three-year-olds who are unhappy that their older siblings get to stay up later. We see the same thing on “Save the Whales” bumper stickers. Why should we save the whales? Because we ought to take care of the world. Why should we take care of the world? Because we just should, that’s why. It’s the right thing to do. There’s that sense of “ought” again.

Certain values can be found in all human cultures, a belief that we act certain ways because they’re the right thing to do. Murdering one’s own people is wrong, for example. Lying and cheating is wrong. So is stealing. Where did this universal sense of right and wrong come from? If we just evolved from the apes, and there is nothing except space, time, and matter, then from where did this moral sense of right and wrong arise?

A moral sense of right and wrong isn’t connected to our muscles or bones or blood. Some scientists argue that it comes from our genes — that belief in morality selects us for survival and reproduction. But if pressed, those same scientists would assure you that ultimate right and wrong don’t exist in a measurable way, and it’s only the illusion of morality that helps us survive. But if one researcher stole another’s data and published results under his own name, all the theories about morality as illusion would go right out the window. I don’t know of any scientist who wouldn’t cry, “That’s not fair!” Living in the real world is a true antidote for sophisticated arguments against right and wrong.

Apologist Greg Koukl points out that guilt is another indicator of ultimate right and wrong. “It’s tied into our understanding of things that are right and things that are wrong. We feel guilty when we think we’ve violated a moral rule, an “ought.” And that feeling hurts. It doesn’t hurt our body; it hurts our souls. An ethical violation is not a physical thing, like a punch in the nose, producing physical pain. It’s a soulish injury producing a soulish pain. That’s why I call it ethical pain. That’s what guilt is — ethical pain.”{4}

The reason all human beings start out with an awareness of right and wrong, the reason we all yearn for justice and fairness, is that we are made in the image of God, who is just and right. The reason we feel violated when someone does us wrong is that a moral law has been broken — and you can’t have a moral law without a moral law giver. Every time we feel that old feeling of, “It’s not fa-a-a-a-a-air!” rising up within us, it’s a signpost pointing us to the existence of God. He has left signposts pointing to Himself all over creation. That’s why we are without excuse.

Evidence of Design Implies a Designer

Mt. RushmoreIf you’ve ever visited or seen pictures of Mount Rushmore (South Dakota USA), you cannot help but look at the gigantic sculpture of four presidents’ faces and wonder at the skill of the sculptor. You know, without having to be told, that the natural forces of wind and rain did not erode the rock into those shapes. It took the skilled hands of an artist.

William Paley made a compelling argument years ago that the intricacies of a watch are so clearly engineered that it cannot be the product of nature: a watch demands a watchmaker. In the same way, the more we discover about our world and ourselves, the more we see that like an expertly-fashioned watch, our world and we ourselves have been finely crafted with intentional design. And design implies a designer.

Since we live in our bodies and take so much of our abilities for granted, it’s understandable that we might miss the evidence of design within ourselves — much like a fish might be oblivious to what it means to be wet. Dr. Phillip Bishop at the University of Alabama, challenges us to consider what would happen if we commissioned a team of mechanical engineers to develop a robot that could lift 500 pounds. And let’s say we also commissioned them to design a robot that could play Chopin. They could probably do that. But what if we asked them to come up with a robot that could do both, and limit the robot’s weight to 250 pounds, and require that it be able to do a variety of similar tasks? They’d laugh in our faces, no matter how much time or money we gave them to do it. But you know, all we’d be asking them to do is to come up with a very crude replication of former football player Mike Reid.{5}

Probably the greatest evidence of design in creation is DNA, the material of which our genes are made, as well as the genetic material for every living thing on the planet. One of the startling discoveries about DNA is that it is a highly complex informational code, so complex that scientists struggle hard to decipher even the tiniest portions of the various genes in every organism. DNA conveys intelligent information; in fact, molecular biologists use language terms — code, translation, transcription — to describe what it does and how it acts. Communication engineers and information scientists tell us that you can’t have a code without a code-maker, so it would seem that DNA is probably the strongest indicator in our world that there is an intelligent Designer behind its existence.

Dr. Richard Dawkins, a professor of biology who writes books and articles praising evolution, said in his book The Blind Watchmaker, “Biology is the study of complicated things that give the appearance of having been designed for a purpose.”{6} Even those who desperately fear the implications of design keep running into it.

Those who deny the evidence of a designer are a lot like the foolish fisherman. If he fails to catch a fish, he says, “Aha! This proves there are no fish!” He doesn’t want to consider the possibility that it might be he is an inept fisherman. Since science cannot measure the intangible or the supernatural, there are many people who say, “Aha! There is no Creator.”{7} Foolish fishermen deny the evidence that God exists and has left His fingerprints all over creation.

The Reliability of the Bible

Every religion has its own holy book, but the Bible is different from all the others. It claims to be the very Word of God, not dropped out of the sky but God-breathed, infused with God’s power as He communicated His thoughts and intent through human writers.

The Bible was written over a period of 1500 years, by about forty different writers, on three different continents. They addressed a wide variety of subjects, and yet the individual books of the Bible show a remarkable consistency within themselves. There is a great deal of diversity within the Bible, at the same time displaying an amazing unity. It presents an internally consistent message with one great theme: God’s love for man and the great lengths to which He went to demonstrate that love.

If you pick up any city newspaper, you won’t find the kind of agreement and harmony in it that is the hallmark of the biblical books. A collection of documents that spans so much time and distance could not be marked by this unity unless it was superintended by one Author who was behind it all. The unity of the Bible is evidence of God’s existence.

One other aspect of the Bible is probably the greatest evidence that God exists and that He has spoken to us in His holy book: fulfilled prophecy. The Bible contains hundreds of details of history which were written in advance before any of them came to pass. Only a sovereign God, who knows the future and can make it happen, can write prophecy that is accurately and always — eventually — fulfilled.

For example, God spoke through the prophet Ezekiel against the bustling seaport and trade center of Tyre. In Ezekiel 26:3-6, He said He would bring nations against her: “They shall destroy the walls of Tyre and break down her towers; and I will scrape her soil from her, and make her a bare rock.” Ezekiel 26-28 has many details of this prophecy against Tyre, which would be like Billy Graham announcing that God was going to wipe New York off the map.

Tyre consisted of two parts, a mainland city and an island a half- mile offshore. The first attack came from the Babylonian king Nebuchadnezzar, who laid siege to Tyre for thirteen years. Finally, his battering rams broke through the walls, and he tore down the city’s towers. But the island part of the city wasn’t yet destroyed, because this prophecy was fulfilled in stages. For 250 years it flourished, until Alexander the Great set his sights on Tyre. Even without a navy, he was able to conquer this island city in what some consider his greatest military exploit. He turned the ruined walls and towers of Old Tyre into rubble, which he used to build a causeway from the mainland to the island. When he ran out of material, he scraped the soil from the land to finish the land- bridge, leaving only barren rocks where the old city used to be. He fulfilled the prophecy, “They will break down your walls and destroy your pleasant houses; your stones and timber and soil they will cast into the midst of the waters”(Ez. 26:12).

Fulfilled prophecy is just one example of how God shows He is there and He is not silent. How else do we explain the existence of history written in advance?

Jesus: The Ultimate Evidence

The most astounding thing God has ever done to show His existence to us is when He passed through the veil between heaven and earth and came to live among us as a man.

Jesus Christ was far more than just a great moral teacher. He said things that would be outrageous if they weren’t true, but He backed them up with even more outrageous signs to prove they were. Jesus claimed not to speak for God as a prophet, but to be God in human flesh. He said, “If you’ve seen Me, you’ve seen the Father” (John 14:9), and, “The Father and I are one” (John 10:30). When asked if He was the Messiah, the promised Savior, He said yes.{8} He told his contemporaries, “Before Abraham was, I am”(John 8:58). The fact that His unbelieving listeners decided then to kill Him shows that they realized He was claiming to be Yahweh, God Almighty.

When Jesus told His followers that He was the Good Shepherd (John 10:11-18), they would immediately be reminded of a passage in the book of Ezekiel where Yahweh God pronounced Himself shepherd over Israel (Ez. 34:1-16). Jesus equated Himself with God.

But words are cheap, so Jesus backed up His words with miracles and signs to validate His truth-claims. He healed all sorts of diseases in people: the blind, the deaf, the crippled, lepers, epileptics, and even a woman with a twelve-year hemorrhage. He took authority over the demons that terrorized and possessed people. He even raised the dead.

Jesus showed His authority over nature, as well. He calmed a terrible storm with just a word. He created food out of thin air, with bread and fish left over! He turned water into wine. He walked on water.

He showed us what God the Father is like; Jesus was God with skin on. He was loving and sensitive, at the same time strong and determined. Children and troubled people were drawn to Him like a magnet, but the arrogant and self-sufficient were threatened by Him. He drenched people with grace and mercy while never compromising His holiness and righteousness.

And after living a perfect life, He showed His love to us by dying in our place on a Roman cross, promising to come back to life. Who else but God Himself could make a promise like thatand then fulfill it? The literal, bodily resurrection of Jesus Christ is the final, greatest proof that there is a God, that Jesus is God Himself, and that God has entered our world and showed us the way to heaven so we can be with Him forever. He said, “I am the way, the truth, and the life; no one comes to the Father except by Me” (John 14:6).

God exists, and He has spoken. He made a “just right” universe that is stamped with clues of its Maker. He placed eternity in our hearts, as Ecclesiastes tells us, and all people have a strong moral streak because we are made in the image of a moral God. The evidence of design in our bodies, our world and the universe is a signpost pointing to a loving, intelligent Designer behind it all. The unity of the Bible and the hundreds of fulfilled prophecies in it show the mind of God behind its creation. And we’ve looked at the way Jesus punched through the space-time continuum to show us what God looks like, and opened the doorway to heaven. Jesus is the clearest evidence of all that God does exist.

There is a God

Note: Antony Flew died in April 2010, approximately two years after this article was written. To our knowledge, he never entered into a saving faith in Jesus Christ. That is a point of great sorrow for us at Probe.

A Much-Maligned Convert

I remember how astonished I was when I first heard the news of his “conversion.” In 2004, longtime British atheist philosopher Antony Flew publicly announced that he now believed in God! I could hardly believe it. Professor Flew had been an atheist for the greater part of his life and, until 2004, his entire academic career. As the “author of over thirty professional philosophical works,” he “helped set the agenda for atheism for half a century.”{1} But then, in 2004, at the age of eighty-one, he changed his mind!

There Is a GodAs one might expect, the reaction to Flew’s announcement varied widely. Theists naturally welcomed the news that one of the most important atheistic philosophers of the past century had come to believe in God. Skeptics and atheists, on the other hand, made little effort to conceal their contempt. Richard Dawkins characterized Flew’s conversion as a kind of apostasy from the atheistic faith and implied that his “old age” likely had something to do with it.{2} Others suggested that the elderly Flew was trying to hedge his bets, fearful of the negative reception he might have in the afterlife. And Mark Oppenheimer, in an article for The New York Times, argued that Flew had been exploited by Christians and that he hadn’t even written the recent book that tells the story of his “conversion.”{3} That book, There Is A God: How the World’s Most Notorious Atheist Changed His Mind, is the subject of this article.

By his own admission, the eighty-four-year-old Flew suffers from “nominal aphasia” and has difficulty recalling names. Nevertheless, it’s quite unfair to insinuate that his belief in God is due to something like senility. He may have problems with his short-term memory, but he’s still capable of explaining what he believes and why. In the introduction to his book he responds to the charge that he now believes in God because of what might await him in the afterlife by pointing out that he doesn’t even believe in an afterlife! “I do not think of myself ‘surviving’ death,” he explains.{4} The charge that Flew didn’t actually write his book is also misleading. While it’s true that he didn’t physically type the words, the content was based upon his previous writings, as well as personal correspondence and interviews with Mr. Varghese. In other words, the ideas in the book accurately represent the views of Professor Flew, even if he didn’t type the text. With that in mind, let’s now take a closer look at some of the arguments and evidence that led “the world’s most notorious atheist” to change his mind about God.

Did Something Come from Nothing?

In a chapter entitled “Did Something Come From Nothing?” Flew addresses issues surrounding the origin of the universe. Is the universe eternal, or did it have a beginning? And if it had a beginning, then how should we account for it?

Flew observes that in his book The Presumption of Atheism, which was written while he was still an atheist, he had argued that “we must take the universe itself and its most fundamental laws as themselves ultimate.” {5} He simply didn’t see any reason to think that the universe pointed to some “transcendent reality” beyond itself.{6} After all, if the universe has always existed, then there may simply be no point in looking for any explanation why.

However, as the Big Bang model of the origin of the universe became increasingly well-established among contemporary cosmologists, Flew began to reconsider the matter. That’s because the Big Bang theory implies that the universe is not eternal, but that it rather had a beginning. And as Flew observes, “If the universe had a beginning, it became entirely sensible, almost inevitable, to ask what produced this beginning.”{7}

Of course, many scientists and philosophers felt quite uncomfortable about what a universe with a beginning might imply about the existence of God. In order to avoid the absolute beginning of the universe, an event which seems to smack of some sort of supernatural creation, they proposed a variety of models that were consistent with the notion that the universe had existed forever. Unfortunately, all these models essentially suffer from the same problem. When carefully examined, it turns out that they can’t avoid the absolute beginning of the universe. Thus, according to Stephen Hawking, “Almost everyone now believes that the universe, and time itself, had a beginning at the Big Bang.”{8}

Reflecting upon his initial encounter with the Big Bang theory while he was still an atheist, Flew writes, “it seemed to me the theory made a big difference because it suggested that the universe had a beginning and that the first sentence in Genesis (‘In the beginning, God created the heavens and the earth’) was related to an event in the universe.”{9} He concludes his discussion by noting that “the universe is something that begs an explanation.”{10} He now believes that the best explanation is to be found in a supernatural creative act of God. Interestingly enough, this view finds dramatic confirmation in the exquisite “fine-tuning” of our universe which allows for the existence of intelligent life.

Did the Universe Know We Were Coming?

Flew observes that “the laws of nature seem to have been crafted so as to move the universe toward the emergence and sustenance of life.”{11} Just how carefully crafted are these laws? According to British physicist Paul Davies, even exceedingly small changes in either the gravitational or electromagnetic force “would have spelled disaster for stars like the sun, thereby precluding the existence of planets.”{12} Needless to say, without planets you and I wouldn’t be here to marvel at how incredibly fine-tuned these constants are. The existence of complex, intelligent life depends on these fundamental constants having been fine-tuned with a precision that virtually defies human comprehension.

So how is the observed fine-tuning to be explained? Flew notes that most scholars opt either for divine design or for what might be called the “multiverse” hypothesis. According to this hypothesis, our universe is just one of many others, “with the difference that ours happened to have the right conditions for life.”{13}

So which of these two theories best explains the amazing fine-tuning of our universe? Flew correctly observes that “there is currently no evidence in support of a multiverse. It remains a speculative idea.”{14} The fact that multiple universes are logically possible does absolutely nothing to prove that they actually exist. Indeed, the multiverse hypothesis appears to be at odds with the widely recognized principle of Ockham’s razor. This principle says that when we’re confronted with two explanations of the same thing, we “should prefer the one that is simpler, that is, the one that uses the fewest number of entities . . . to explain the thing in question.”{15}

Now clearly in the case before us, the theory of divine design, which posits only one entity to explain the observed fine-tuning of our universe, is much simpler than the multiverse hypothesis, which posits a potentially infinite number of entities to explain the same thing! The philosopher Richard Swinburne likely had Ockham’s razor in mind when he wrote, “It is crazy to postulate a trillion (causally unconnected) universes to explain the features of one universe, when postulating one entity (God) will do the job.”{16}

The observed fine-tuning of our universe is one more reason why Antony Flew now believes there is a God. And as we’ll see next, the mystery of life’s origin is yet another.

How Did Life Go Live?

One of the reasons consistently cited by Flew for changing his mind about the existence of God has to do with the almost insuperable difficulties facing the various naturalistic theories of the origin of life. In particular, Flew observes, there is a fundamental philosophical question that has not been answered, namely, “How can a universe of mindless matter produce beings with intrinsic ends, self-replication capabilities, and ‘coded chemistry’?”{17}

When considering the origin of life from non-living matter, it’s crucially important to note a fundamental difference between the two. “Living matter possesses an inherent . . . end-centered organization that is nowhere present in the matter that preceded it.”{18} For example, lifeless rocks do not give evidence of goal-directed behavior, but living creatures do. Among the various goals one might list, living beings seek to preserve and reproduce themselves.

This leads naturally to the second difficulty, namely, providing a purely naturalistic account of the origin of organisms that are able to reproduce themselves. As philosopher David Conway points out, without this ability “it would not have been possible for different species to emerge through random mutation and natural selection.” Since different species can’t emerge from organisms that can’t reproduce themselves, one can’t claim that self-reproduction emerged through the evolutionary process. Conway concludes that such difficulties “provide us with reason for doubting that it is possible to account for existent life-forms . . . without recourse to design.”{19}

The final difficulty Flew raises concerns a purely naturalistic origin of “coded chemistry.” Scientists have discovered that the genetic code functions exactly like a language. But as the mathematician David Berlinski asks, “Can the origins of a system of coded chemistry be explained in a way that makes no appeal whatever to the kinds of facts that we otherwise invoke to explain codes and languages?”{20} In other words, if every other code and language we’re aware of results from intelligence, then why think the genetic code is any different? As physicist Paul Davies muses, “The problem of how meaningful . . . information can emerge spontaneously from a collection of mindless molecules subject to blind and purposeless forces presents a deep conceptual challenge.”{21}

Ultimately, such challenges became too much for Flew. He concludes his discussion of these difficulties by noting, “The only satisfactory explanation for the origin of such ‘end-directed, self-replicating’ life as we see on earth is an infinitely intelligent Mind.”{22}

The Self-Revelation of God in Human History

In a fascinating appendix to his book, Flew has a dialogue with prominent New Testament scholar N.T. Wright about Jesus. Although Flew is not a Christian and continues to be skeptical about the claims for Jesus’ bodily resurrection, he nonetheless asserts that this claim “is more impressive than any by the religious competition.”{23} But why is this? And what sort of evidence is there for the resurrection of Jesus? This is one of the questions to which N.T. Wright responds in his dialogue with Flew.

Although we can only scratch the surface of this discussion, Wright makes two points that are especially worth mentioning: the historicity of the empty tomb and the post-mortem appearances of Jesus. But why think these events actually happened as the Gospels claim? Because, says Wright, if the tomb were empty, but there were no appearances, everyone would have concluded that the tomb had been robbed. “They would never have talked about resurrection, if all that had happened was an empty tomb.”{24}

On the other hand, suppose the disciples saw appearances of Jesus after His crucifixion. Would this have convinced them of His resurrection if His tomb were not empty? No, says Wright. The disciples knew all about “hallucinations and ghosts and visions. Ancient literature—Jewish and pagan alike—is full of such things.”{25} So long as Jesus’ body was still in the tomb, the disciples would never have believed, much less publicly proclaimed, that He had been raised from the dead. This would have struck them as self-evidently absurd. For these and other reasons, Wright concludes that the empty tomb and appearances of Jesus are historical facts that need to be reckoned with. The question then becomes, “How does one account for these facts? What is the best explanation?”

Wright concludes that, as a historian, the best explanation is that “Jesus really was raised from the dead,” just as the disciples proclaimed. This is clearly a sufficient explanation of Jesus’ empty tomb and post-mortem appearances. But Wright goes even further. “Having examined all the other possible hypotheses,” he writes, “I think it’s also a necessary explanation.”{26}

How does Flew respond to this claim? Asking whether divine revelation in history is really possible, he notes that “you cannot limit the possibilities of omnipotence except to produce the logically impossible. Everything else is open to omnipotence.”{27} Flew has indeed come a long way from his former atheist views. For those of us who are Christians, we can pray that he might come further still.
