Dr. Michael Gleghorn briefly examines some of the reasons why noted Christian philosopher William Lane Craig believes that Christianity is an eminently reasonable faith.
Reasonable Faith
One of the finest Christian philosophers of our day is William Lane Craig. Although he has become very well known for his debates with atheists and skeptics, he’s also a prolific writer. To date, he has authored or edited over thirty books and more than a hundred scholarly articles.{1} His published work explores such fascinating topics as the evidence for the existence of God, the historical evidence for the resurrection of Jesus, divine foreknowledge and human freedom, and God’s relationship to time. In 2007 he started a web-based apologetics ministry called Reasonable Faith (www.reasonablefaith.org). The site features both scholarly and popular articles written by Craig, audio and video recordings of some of his debates, lectures, and interviews, answers to questions from his readers, and much more.
But before he launched the Reasonable Faith Web site, Craig had also authored a book by the same title. One of the best apologetics books on the market, a revised and updated third edition was recently released. His friend and colleague, the philosopher J. P. Moreland, endorsed Craig’s ministry with these words:
It is hard to overstate the impact that William Lane Craig has had for the cause of Christ. He is simply the finest Christian apologist of the last half century, and his academic work justifies ranking him among the top one percent of practicing philosophers in the Western world. Besides that, he is a winsome ambassador for Christ, an exceptional debater, and a man with the heart of an evangelist. . . . I do not know of a single thinker who has done more to raise the bar of Christian scholarship in our generation than Craig. He is one of a kind, and I thank God for his life and work.{2}
Although the book has been described as “an admirable defense of basic Christian faith,”{3} many readers will find the content quite advanced. According to Craig, “Reasonable Faith is intended primarily to serve as a textbook for seminary level courses on Christian apologetics.”{4} For those without much prior training in philosophy, theology, and apologetics, this book will make for some very demanding reading in places. But for those who want to seriously grapple with an informed and compelling case for the truth of Christianity, this book will richly repay one’s careful and patient study.
Although we cannot possibly do it justice, in the remainder of this article we will briefly consider at least some of the reasons why Craig believes that biblical Christianity is an eminently reasonable faith.
The Absurdity of Life Without God
Imagine for a moment that there is no God. What implications would this have for human life? Science tells us that the universe is not eternal, but that it rather had a beginning. But if there is no God, then the universe must have come into being, uncaused, out of nothing! What’s more, the origin of life is nothing more than an unintended by-product of matter, plus time, plus chance.{5} No one planned or purposed for life to arise, for if there is no God, there was no one to plan or purpose it. And human beings? We are just the unpredictable result of a long evolutionary process that never had us in mind. In fact, if one were to rewind the history of life to its beginning, and allow the evolutionary process to start anew, it’s virtually certain that none of us would be here to think about it! After all, without an intelligent Agent guiding this long and complicated process, the chances that our species would accidentally emerge a second time is practically zero.{6}
Depressing as it is, this little thought experiment provides the appropriate backdrop for Craig’s discussion of the absurdity of life without God. In his view, if God does not exist, then human life is ultimately without meaning, value, or purpose. After all, if human beings are merely the accidental by-products of the unintended forces of nature, then what possible meaning could human life have? If there is no God, then we were not created for a purpose; we were merely “coughed” into existence by mindless material processes.
Of course, some might wonder why we couldn’t just create some meaning for our lives, or give the universe a meaning of our own. But as Craig observes, “the universe does not really acquire meaning just because I happen to give it one . . . . for suppose I give the universe one meaning, and you give it another. Who is right? The answer, of course, is neither one. For the universe without God remains objectively meaningless, no matter how we regard it.”{7}
Like it or not, if God does not exist, then the universeand our very livesare ultimately meaningless and absurd. The difficulty is, however, that no one can really live consistently and happily with such a view.{8} Although merely recognizing this fact does absolutely nothing to show that God actually exists, it should at least motivate us to sincerely investigate the matter with an open heart and an open mind. So let’s now briefly consider some of the reasons for believing that there really is a God.
The Existence of God
In the latest edition of Reasonable Faith, Craig offers a number of persuasive arguments for believing that God does, in fact, exist. Unfortunately, we can only skim the surface of these arguments here. But if you want to go deeper, his book is a great place to start.
After a brief historical survey of some of the major kinds of arguments that scholars have offered for believing that God exists, Craig offers his own defense for each of them. He begins with a defense of what is often called the cosmological argument. This argument takes its name from the Greek word kosmos, which means “world.” It essentially argues from the existence of the cosmos, or world, to the existence of a First Cause or Sufficient Reason for the world’s existence.{9} Next he defends a teleological, or design, argument. The name for this argument comes from the Greek word telos, which means “end.” According to Craig, this argument attempts to infer “an intelligent designer of the universe, just as we infer an intelligent designer for any product in which we discern evidence of purposeful adaptation of means to some end (telos).”{10} After the design argument, he offers a defense of the moral argument. This argument “implies the existence of a Being that is the embodiment of the ultimate Good,” as well as “the source of the objective moral values we experience in the world.”{11} Finally, he defends what is known as the ontological argument. Ontology is the study of being, and this much-debated argument “attempts to prove from the very concept of God that God exists.”{12}
Taken together, these arguments provide a powerful case for the existence of God. As Craig presents them, the cosmological argument implies the existence of an eternal, immaterial, unimaginably powerful, personal Creator of the universe. The design argument reveals an intelligent designer of the cosmos. The moral argument reveals a Being who is the transcendent source and standard of moral goodness. And the ontological argument shows that if God’s existence is even possible, then He must exist!
But suppose we grant that all of these arguments are sound. Why think that Christianity is true? Many non-Christian religions believe in God. Why think that Christianity is the one that got it right? In order to answer this question we must now confront the central figure of Christianity: Jesus of Nazareth.
The Son of Man
When the previous edition of Reasonable Faith was published in 1994, most New Testament scholars thought that Jesus had never really claimed to be the Messiah, or Lord, or Son of God. But a lot has happened in the intervening fourteen years, and “the balance of scholarly opinion on Jesus’ use of Christological titles may have actually tipped in the opposite direction.”{13}
For example, we have excellent grounds for believing that Jesus often referred to himself as “the Son of Man.”{14} Although some believe that in using this title Jesus was merely referring to himself as a human being, the evidence suggests that he actually meant much more than that. Note, for example, that “Jesus did not refer to himself as ‘a son of man,’ but as ‘the Son of Man.'”{15} His use of the definite article is a crucially important observation, especially in light of Daniel 7:13-14.
In this passage Daniel describes a vision in which “one like a son of man” comes before God with the clouds of heaven. God gives this person an everlasting kingdom and we are told that “all peoples, nations and men of every language worshiped him” (Dan. 7:14). It’s clear that Daniel’s “son of man” is much more than a human being, for he’s viewed as an appropriate object of worship. Since no one is worthy of worship but God alone (see Luke 4:8), the “son of man” must actually be divine, as well as human.
According to Mark, at Jesus’ trial the high priest pointedly asked him if he was the Christ (or Messiah), “the Son of the Blessed One.” Jesus’ response is astonishing. “I am,” he said, “And you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven” (Mark 14:61-62). Here Jesus not only affirms that he is the Messiah and Son of God, he also explicitly identifies himself with the coming Son of Man prophesied by Daniel.{16} Since we have excellent reasons for believing that Jesus actually made this radical claim at his trial, we’re once again confronted with that old trilemma: if Jesus really claimed to be divine, then he must have been either a lunatic, a liar, or the divine Son of Man!
Now most people would probably agree that Jesus was not a liar or a lunatic, but they might still find it difficult to accept his claim to divinity. They might wonder if we have any good reasons, independent of Jesus’ claims, for believing his claims to be true. As a matter of fact we do!
The Resurrection of Jesus
Shortly after Jesus’ crucifixion, on the day of Pentecost, the apostle Peter stood before a large crowd of people gathered in Jerusalem and made a truly astonishing claim: God had raised Jesus from the dead, thereby vindicating his radical personal claims to be both Lord and Messiah (see Acts 2:32-36). The reason this claim was so incredible was that the “Jews had no conception of a Messiah who, instead of triumphing over Israel’s enemies, would be shamefully executed by them as a criminal.”{17} Indeed, according to the Old Testament book of Deuteronomy, “anyone who is hung on a tree is under God’s curse” (21:22-23). So how could a man who had been crucified as a criminal possibly be the promised Messiah? If we reject the explanation of the New Testament, that God raised Jesus from the dead, it’s very difficult to see how early Christianity could have ever gotten started. So are there good reasons to believe that Jesus really was raised from the dead?
According to Craig, the case for Jesus’ resurrection rests “upon the evidence for three great, independently established facts: the empty tomb, the resurrection appearances, and the origin of the Christian faith.”{18} He marshals an extensive array of arguments and evidence in support of each fact, as well as critiquing the various naturalistic theories which have been proposed to avoid the resurrection. He concludes by noting that since God exists, miracles are possible. And once one acknowledges this, “it’s hard to deny that the resurrection of Jesus is the best explanation of the facts.”{19}
This brings us to the significance of this event. According to the German theologian Wolfhart Pannenberg:
The resurrection of Jesus acquires such decisive meaning, not merely because someone
. . . has been raised from the dead, but because it is Jesus of Nazareth, whose execution was instigated by the Jews because he had blasphemed against God. If this man was raised from the dead, then . . . God . . . has committed himself to him. . . . The resurrection can only be understood as the divine vindication of the man whom the Jews had rejected as a blasphemer.{20}
In other words, by raising Jesus from the dead, God has put His seal of approval (as it were) on Jesus’ radical personal claims to be the Messiah, the Son of God, and the divine Son of Man! This forces each of us to answer the same haunting question Jesus once asked his disciples, “Who do you say I am?” (Matt. 16:15).
