Yeah, the Rob Bell posts are getting kind of old, but more and more stuff just keeps coming out that is too good to pass up. This time it comes from Frank Turk from Pyromaniacs (one of the top Christian blogs out there) in the form of one of his open letters. Good stuff.
When the content of Bell's latest book became public, John Piper tweeted "Farewell, Rob Bell," which incited a firestorm of criticism about the tweets meaning, although I think Piper was simply referring to the fact that with this book Bell was taking a significant step away from orthodox Christianity. From what I've been reading, I think Piper's tweet may have been prophetic. It's getting harder and harder to take Rob Bell and those like him seriously. These guys are so far away from orthodoxy at some points that it's becoming difficult to be a part of their "conversation."
