Timothy Keller, the founding pastor of Redeemer Presbyterian Church in New York City, addresses the frequent doubts that skeptics, and even ardent believers, have about religion. Using literature, philosophy, real-life conversations, and potent reasoning, Keller explains how the belief in a Christian God is, in fact, a sound and rational one. To true believers he offers a solid platform on which to stand their ground against the backlash to religion created by the Age of Skepticism. And to skeptics, atheists, and agnostics, he provides a challenging argument for pursuing the reason for God.
