Kinnaman, president of the Barna Institute, was inspired to write this book when Lyons (of the Fermi Project) commissioned him to do extensive research on what young Americans think about Christianity. Lyons had a gut-level sense that something was desperately wrong, and three years of research paints exactly that picture. 'Mosaics' and 'Busters' (the generations that include late teens to early 30-somethings) believe Christians are judgmental, antihomosexual, hypocritical, too political and sheltered. Rather than simply try to do a PR face-lift, Kinnaman looks at ways in which churches' activities actually may have been unchristian and encourages a return to a more biblical Christianity, a faith that not only focuses on holiness but also loves, accepts and works to understand the world around it. It would be possible to get lost in the numbers, but the authors use numerous illustrations from their research and life experiences and include insights at the end of every chapter from Christian leaders like Charles Colson, John Stott, Brian McLaren and Jim Wallis. This is a wonderful, thoughtful book that conveys difficult truths in a spirit of humility.
