I read this book in two sittings and wanted very much to like it. My biggest issue was his preoccupation with American destruction and calls for restoration. Unless I misread the gospels, the Kingdom of God movement is global and international and the most important thing to ever occur in world history. If America severely declines will the Christian faith perish? Christianity has been around almost 1800 years longer than the United States. What is the place of civil religion in Barna's book? Are we Americans first and Christians second? Apparently so, from my reading of this book. Barna's ideal of the seven tribes joining together to save America is weak. Much of the tribal descriptions tended toward the stereotypical, especially how groups voted in the presidential elections of 2000 and 2004. I did like the 20 shared values charting but it was poorly developed in the book itself. It would have been helpful to see more connection made between them and his 12 Commitments of Great Followers.
