The Reason for God: Belief in an Age of Skepticism by Timothy Keller

The Reason for God by Timothy Keller responds to common doubts about Christian belief using literature, philosophy and conversations with skeptics. Keller makes a case for faith while asking readers to examine the assumptions behind both belief and unbelief.

Published by Penguin Books, it is a work of Christian apologetics rather than a neutral survey of world religions. It offers an argument to engage with, not a claim that every religious question has been settled.
