A New York Times bestseller people can believe in, by "a pioneer of the new urban Christians" (Christian Today magazine). Timothy Keller, the founding pastor of Redeemer Presbyterian Church in New York City, addresses the frequent doubts that skeptics and non-believers bring to religion. Using literature, philosophy, anthropology, pop culture, and intellectual 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 against the backlash toward religion spawned by the Age of Skepticism. And to skeptics, atheists, and agnostics he provides a challenging argument for pursuing the reason for God.
