George Barna and David Kinnaman are interviewed (excerpt) by Jodi Hickerson of Mission Church, Ventura, California, about their new book, Churchless: Understanding Today's Unchurched and How to Connect with Them. Barna says that when interviewing young Americans for the study, he was shocked at “how little they (young Americans) know about Christian history” and about how the church has added, in term of value, to our society.
