I Repent: A Journey Into the Heart

The Scriptures repeatedly admonish believers to repent--to change the way they think and act. Having grown up in the church, Caleb Mathis was familiar with the word "repentance," but not necessarily with its practice. A summer road trip would change all that.

Part travel memoir, part personal treatise of faith, this is the sound of a Christ-believing boy straining to grow into a Christ-following man. Each stop along the road trip's route revealed a new lesson, another area in which God was demanding repentance. What started as an adventure into the American heartland ended as a voyage into a place infinitely more exotic, beautiful, and dangerous: the human heart.

How does a life change? One mile at a time.
