I'm not a Warren fan, but that's simply a lie, and God hates liars. You'd do well to repent. It's pure garbage: he has never, ever said anything like that nor does he believe it.
When you listen to Rick Warren talk, Jesus is mighty hard to find. People who want to follow Warren off a cliff are welcome to it. Maybe they can join him in a chorus of "Purple Haze". He is a false teacher.
Well, even Jesus didn't save the whole world. Rick thinks he can with his brand spankin' new (see Ecclesiastes) methods.
