Book excerpt: Drawing on Jesus's example of walking, bestselling author Mark Buchanan explores one of the oldest spiritual practices of our faith. What happens when we literally walk out our Christian life? We discover the joy of traveling at the speed of our soul. We often act as if faith is only about the mind. But what about our bodies? What does our physical being have to do with our spiritual life? When the Bible exhorts us to walk in the light, or walk by faith, or walk in truth, it means these things literally as much as figuratively. The Christian faith always involves walking out, as again and again we find the holy in the ordinary. "Come, follow me," Jesus said, and then he was off. The most obvious thing about Jesus's method of discipleship, in fact, is that he walked and invited others to walk with him. Jesus is always "on the way," "arriving," "leaving," "approaching," "coming upon." It's in the walking that his disciples are taught, formed, tested, empowered, and released. Part theology, part history, part field guide, God Walk explores walking as spiritual formation, walking as healing, walking as exercise, walking as prayer, walking as pilgrimage, suffering, friendship, and attentiveness. It is a book about being alongside the God who, incarnate in Jesus, turns to us as he passes by--always on foot--and says simply, "Come, follow me." With practical insight and biblical reflections told in his distinct voice, Buchanan provides specific walking exercises so you can immediately implement the practice of going "God speed." Whether you are walking around the neighborhood or hiking in the mountains, walking offers the potential to awaken your life with Christ as it revives body and soul.
