If he had all the answers, why did the question of God’s existence continue to preoccupy him? Perhaps Lewis would say we can never explain away God. Nor can we find rest until that deep-seated desire (experienced by both Freud and Lewis) is satisfied.

Lewis said that when he was an atheist, his life also was full of contradictions. He writes: “I was at this time living, like so many Atheists . . . in a whirl of contradictions. I maintained that God did not exist. I was also very angry with God for not existing. I was also equally angry with Him for creating a world . . . why should creatures have the burden of existence forced on them without their consent?” Even as an atheist, Lewis realized his ambivalence toward God—a part of him wanting desperately that God not exist, another part strongly desiring His existence.
