Another Book Recommendation on Religious Life in the USA
If you are into stats and the state of Christianity in the USA, then I'd like to recommend Christians Are Hate-Filled Hypocrites and Other Lies You've Been Told, by Bradley Wright. It is a statistical look at religious life in the USA and is filled with data.
In it he challenges ideas like evangelical Christianity is shrinking in significant ways. The youth are being lost to secularism and other popular ideas you hear in church these days (and also in the media). He backs up his counter claims with the bevy of surveys and presents the data in easy readable form. In particular, in spots, he argues why data presented by George Barna (and often used by evangelicals) is flawed. He also challenges Josh McDowell's take on what is happening with our youth. This is a fascinating read. It also is clearly and simply written so it is easy to follow.
