Kevin DeYoung has written what is the most helpful post I have read on the controversy surrounding Rob Bell and the promotion of his new book. You ought to read it when you get a chance.
In case you are wondering why I have been posting on this, the answer is easy: Rob Bell has influence. He is an internationally known pastor, preacher, and writer. Not long ago some evangelicals were calling him the next Billy Graham. His books and Nooma videos have been and continue to be enormously popular among Christians. Therefore, his continued drift away from historic Christian orthodoxy on issues like the Bible's reliability, the atonement, the resurrection, the judgement, and the eternal state rightfully concern many pastors.
