The Reason for God by Timothy Keller

Keller is the pastor of Redeemer Presbyterian Church in Manhattan. He and his wife founded the church in 1989 and it now has nearly 6,000 attending with five services. The subtitle of this book is Belief in an Age of Skepticism. The is the best book on Christian apologetics I have read (and having owned a Christian bookstore for over 30 years, I have read many). Keller takes a fresh approach to doubt. The doubter of Christianity must defend how he knows his own belief to be true. One cannot ask more of Christianity than one asks of his or her own beliefs. This is a great book to suggest your doubting friend read. Of course, you would be willing to read a book by Hitchens, Dawkins, or another atheist, right? This is how the conversation begins.
