What good is God in a world where terrorists attack tourist sites in Mumbai, where women and children are sold into sexual slavery, and where six million people in South Africa alone suffer with HIV/AIDS? Does faith really matter when you're struggling with an addiction, or when you get laid off from your job and your home is in foreclosure? Featuring a new intro, fresh design and compelling study questions in this expanded edition, journalist and spiritual seeker Philip Yancey travels the globe in search of an answer to a query posed the world over. His discoveries of redemption, hope, and grace provide evidence that faith really does make a difference, even when belief is severely tested.
