George Barna is the founder of The Barna Group, a market research firm specializing in studying the religious beliefs and behavior of Americans, and the intersection of faith and culture. Barna is known for providing extensive surveys regarding Christianity and the state of the church. (Wikipedia). Barna’s new book on U.S. Christians, “Futurecast,” tracks changes from 1991 to 2011, in annual national survey. In 1991, 24 percent were “unchurched.” Today, it’s 37 percent. Whatever the church is doing is not working and Barna blames pastors for these findings. Read.
