C.S. Lewis

Oxford and Cambridge medievalist who spent his youth as a sharp-tongued atheist before being argued, and surprised, into Christianity by friends like J.R.R. Tolkien. He wrote about faith the way a lawyer cross-examines: Mere Christianity, The Problem of Pain, The Screwtape Letters, Miracles. He also wrote The Chronicles of Narnia for children, and after the death of his wife Joy Davidman he wrote A Grief Observed under a pseudonym — the journal of a believer falling apart in real time. He is the rare apologist who never lost the ability to write about doubt as honestly as belief.
