Book excerpt: From the author of A New Kind of Christianity comes a bold proposal: only doubt can save the world and your faith. ONE of the Best Spiritual Books of 2021—Spirituality & Practice "Will help you live fuller and breathe easier..” —Glennon Doyle Sixty-five million adults in the U.S. have dropped out of active church attendance and about 2.7 million more are leaving every year. Faith After Doubt is for the millions of people around the world who feel that their faith is falling apart. Using his own story and the stories of a diverse group of struggling believers, Brian D. McLaren, a former pastor and now an author, speaker, and activist shows how old assumptions are being challenged in nearly every area of human life, not just theology and spirituality. He proposes a four-stage model of faith development in which questions and doubt are not the enemy of faith, but rather a portal to a more mature and fruitful kind of faith. The four stages—Simplicity, Complexity, Perplexity, and Harmony—offer a path forward that can help sincere and thoughtful people leave behind unnecessary baggage and intensify their commitment to what matters most.
