C. S. Lewis (1898 – 1963), a former atheist, is one of the most widely read Christian apologetic author today. He is the mind behind the Narnia entertainment series, and some of his most popular Christian writings read widely today are Mere Christianity and The Screwtape Letters.

“Atheism turns out to be too simple. If the whole universe has no meaning, we should never have found out that it has no meaning.”

-C.S. Lewis (‘Mere Christianity.’)

“Supposing there was no intelligence behind the universe, no creative mind. In that case, nobody designed my brain for the purpose of thinking. It is merely that when the atoms inside my skull happen, for physical or chemical reasons, to arrange themselves in a certain way, this gives me, as a by-product, the sensation I call thought. But, if so, how can I trust my own thinking to be true? It’s like upsetting a milk jug and hoping that the way it splashes itself will give you a map of London. But if I can’t trust my own thinking, of course I can’t trust the arguments leading to Atheism, and therefore have no reason to be an Atheist, or anything else. Unless I believe in God, I cannot believe in thought: so I can never use thought to disbelieve in God.”

-C.S. Lewis (‘The Case for Christianity.’)

“A young man who wishes to remain a sound Atheist cannot be too careful of his reading. God is, if I may say it, very unscrupulous.”

-C.S. Lewis (‘Surprised by Joy.’)
