I picked up Timothy Keller's The Reason for God and was blown away. This looks like a must read.
From Publishers Weekly
In this apologia for Christian faith, Keller mines material from literary classics, philosophy, anthropology and a multitude of other disciplines to make an intellectually compelling case for God. Written for skeptics and the believers who love them, the book draws on the author's encounters as founding pastor of New York's booming Redeemer Presbyterian Church. One of Keller's most provocative arguments is that all doubts, however skeptical and cynical they may seem, are really a set of alternate beliefs.
