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.
