Smith, a pastor and former news reporter and talk show host who contributes to the Washington Post's "On Faith" blog, challenges ordinary people to let God use them for impossible tasks. Such submission requires "crazy faith," knowing God will bring success even when the task seems impractical and illogical. Appropriate for anyone experiencing a calling or facing a crisis, the author cautions that "fear cancels faith" and must be overcome by staring down life's Goliaths. Following an introductory chapter, each subsequent chapter includes the solidly researched life story of someone with "crazy faith," followed by a "Crazy-Faith Challenge" for group study or individual reflection. From biblical characters like Moses and King David to heroes of black history like Harriet Tubman and Nelson Mandela, these driven dreamers aren't as ordinary as the title asserts. Yet their humble beginnings suggest anyone could develop similar determination. Read as a whole, their patchwork of history becomes a united tale of faith against all odds. Feisty, enthusiastic and encouraging, the author's language will inspire readers to face seemingly insurmountable challenges with "superhuman energy."
