Rick Warren teaches the whole counsel of God.
He does not seem to talk about hell etc. in the traditional ways of a hundred years ago. Perhaps that's because that audience is dead.
He's doing The Master's Busioness. I'd do it a little differently. I'm not him.
And, I don't have the mandate God gave him to fulfill.
People are free to read his book and make up their own minds.
Warren is only one of many who are preaching a watered down message.
