Talking About the Problem of Evil

Problem of pain

T.S. Weaver has put together an intellectual response to the problem of evil that includes a theology of evil and suffering, and a philosophical/theological series of proper defenses of God and His righteousness considering evil.

What is Evil?

The problem of evil is famous. This problem is personal because my wife stayed stuck as an agnostic for a long time. An agnostic, by the way, is a person who says they don’t know if there is a God. Like so many people, she thought that if you believe in a God who is all good and all-powerful, then the presence of evil and suffering creates a problem.

Atheist philosopher David Hume said, “Epicurus’s old questions are yet unanswered. Is he willing to prevent evil, but not able? Then he is impotent. Is he able to but not willing? Then he is malevolent. Is he both able and willing? Whence then is evil?”

Let’s address this. I’ll give you a roadmap of where we’re going. First, we need to address how one can even object to evil. Second, I will talk about what evil is and is not. Then I will talk about some possible reasons God allows evil. Finally, I’ll close with God’s solution.

To start, if this challenge were raised by an atheist, we need to address the moral argument. If there is right and wrong, then they are grounded in the existence of a good and moral God. Because without an absolute Moral Law, which requires an absolute Moral Law Giver, the atheist has no grounds for a complaint against evil.

Former atheist C.S. Lewis summarizes how this thinking eventually guided him to Christianity: “My argument against God was that the universe seemed so cruel and unjust. But how had I got this idea of just and unjust? A man does not call a line crooked unless he has some idea of a straight line. What was I comparing this universe with when I called it unjust?”

Evil is not a “thing” that exists; and God is not the cause. Both Augustine and Thomas Aquinas point out that evil is not a real entity in the world. This means evil is not a material or a phenomenon that exists by itself. It’s like darkness, which is not a created thing; it’s the absence of light. Evil describes a deficiency or denial of good. Philosophers call this deficiency a privation. Evil is what occurs once the good is altered or distorted. In Genesis 1 and 2, God told us all that existed was good. Evil was not an innovation, but a distortion. So, God is not the creator or author of evil.

The Best-of-All-Possible-Worlds

Let us consider the best-of-all-possible-worlds argument. The place to start is God’s omniscience. This allows God to understand all possibilities. If God knows all possibilities, God knows all possible worlds. Since God is also completely good, He always wants and works out the best world and the best way.

Leibniz (the philosopher who came up with this defense) wrote, “The first principle of existences is the following proposition: God wants to choose the most perfect.”

The power of this argument is to show that out of every world that a good God could have produced, His decision to generate this one means this creation is good.

There are several principles that tie into this defense.

The first major principle is centered on the truth that God acts for worthy causes. Again, God’s omniscience presumes that before God decides which world to produce, He understands the value of every possible world. This also implies God always decides on the base of sensible, stable rationales. This is called the “principle of sufficient reason.”

To believe God can intercede in what he has formed with sufficient reason, even to avoid or restrict evil, would be like a soldier who abandons his post and knowingly allows enemy infiltration to instead stop a colleague from drinking while in uniform. The soldier ends up allowing a greater evil in order to stop a lesser evil.

Another principle that reinforces this argument is the principle of “pre-established harmony.”

Leibniz describes it this way: “For, if we were capable of understanding the universal harmony, we should see that what we are tempted to find fault with is connected to the plan most worthy of being chosen; in a word we should see, and should not believe only, that what God has done is the best.”

Human Free Will

Above, we covered the principle of sufficient reason as part of the best-of-all possible worlds. The last principle of the best-of-all-possible-worlds is human free will. For Leibniz, this idea was just a principle in part of his greater defense. For Augustine, C.S. Lewis, and Alvin Plantinga it was an entire defense by itself. In its simplest form, it goes something like this: God set us up not to be machines but free agents with the power to choose.

If God were to make us capable of freely choosing the good, He had to create us also able to freely choose evil. Consequently, our free will can be misused and that is the explanation for evil.

Jean-Paul Sartre communicates this wonderfully: “The man who wants to be loved does not desire the enslavement of the beloved. . . . If the beloved is transformed into an automaton, the lover finds himself alone.”  God knows that a better world is created, if human beings are infused with free will, even if they decide to behave corruptly.

Were God to force us to make good choices, we would not be making choices at all, but simply implementing God’s instructions like when a computer runs a program.

For humans to have the capability to be ethically good, free will is necessary. Morality hangs on our capability to freely choose the good.

Plantinga asserts, “God creates a world containing evil, and he has a good reason for doing so.”  John Stackhouse Jr. says, “God, to put it bluntly, calculates the cost-benefit ratio and deems the cost of evil to be worth the benefit of loving and enjoying the love of these human beings.”

Stackhouse sums up Plantinga’s argument like this:

“God desired to love and be loved by other beings. God created human beings with this in view. To make us capable of such fellowship, God had to give us the freedom to choose, because love, though it does have its elements of ‘compulsion,’ is meaningful only when it is neither automatic nor coerced. This sort of free will, however, entailed the danger that it would be used not to enjoy God’s love and to love God in return, but to go one’s own way in defiance of both God and one’s own best interest.”

God created us with free will because our decision to say “yes” to Him is only a real choice if we are also free to say “no” to Him.

The Greater Good

To review, so far, we’ve addressed how one can even object to evil, in the moral argument. We’ve talked about what evil is and is not, and the idea of it being a privation. We’ve talked about some possible reasons God allows evil, which included the best-of-all-possible-worlds argument and the free will defense. Now I want to go over the greater good principle. While all the arguments I’ve given so far are intellectual and do not necessarily help with the emotional side of evil and suffering, this principle is especially delicate. I say “delicate” because this defense may not help a questioner much if they have been a victim of a seemingly very unwarranted evil, and/or if they are still carrying anger or bitterness.

Again, the topic we are examining is the greater good principle, which argues that certain evils are needed in the world for certain greater goods to happen. To put it another way, certain evils in this world are called for, as greater goods stem after them. For instance, nobody would believe a doctor who cuts out a cancerous tumor is being evil because he made an incision on the patient. The surgery incision is much less evil than letting the tumor develop. The greater good is the patient being cancer-free. Parents who penalize children for poor conduct with the loss of toys or privileges or even giving spankings are instigating pain (particularly from the kid’s viewpoint). Although, without this discipline, the other possibility is that the kid will develop into a grownup with no discipline and would consequently face much more suffering. We do not understand in this world all the good God is preparing; therefore, we need to trust that God is good even when we can’t see it and we can’t understand the larger picture of what He’s doing.

Plus, nearly all individuals will award some truth to the saying ascribed to Nietzsche: “Whatever doesn’t kill me makes me stronger.” Consequently, the principle of allowing pain in the short term to bring about a greater contentment eventually is legitimate and one we know and use ourselves. That implies there is no mandatory contradiction between God and the reality of evil and suffering.

The Cross

Finally, I end with the cross and the hope of Christianity. Jesus agonized in enduring the nastiest evil that can be thrown at him: denial by His own adored people; abhorrence from the authorities in His own religion; unfairness at the hands of the Roman court; unfaithfulness and disloyalty from His closest friends; the public disgrace of being stripped nude and mocked as outrageous “King of the Jews”; anguish in the agony of crucifixion; and the continuous weight of the lure to despair altogether, to crash these unappreciative beings with shocks of heaven, to recommence with a new race, to assert Himself. Instead, Jesus remained there, embracing into Himself the sins of the world, keeping Himself in position as His foes wreaked their most terrible treatment.

Our faith in a good God is sensible, because Jesus suffered on our behalf, and took the punishment we deserve. He understands what it is to suffer. He has lived there.

The cross was a world-altering occasion where the love and compassion of God dealt efficiently with the immensity of human sin. His death and resurrection show evil is trounced, and death has been slain. Contemplate the many implications of the atonement: Jesus is the Victor, He has paid our ransom, God’s wrath has been satisfied, and Jesus is the substitution for the offenses we have perpetrated.

As if that is not enough, the Christian narrative ends with faith in the future where complete justice will be done, and all evils will be made right. When Christ returns, He will not once more give in to mortal agencies and quietly accept evil. He will come back to deliver justice. The Bible’s definitive solution to the problem of evil is that evil will be dealt with. God will create a new heaven and a new earth for persons God has loved so long and so well. This is the core of our faith in the middle of pain and suffering.

In conclusion, what I’ve just presented to you, and what my wife eventually figured out, is that evil is not a thing created by God. A valid complaint against evil cannot be made without the existence of God. God has plausible reasons for allowing evil. And He clearly has a plan to defeat it. All He wants you to do is trust Him.

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

sunlight in forest

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).
