Rob Bell is featured in a small-ish article of Time magazine. I have to confess, I don't know much about him. I understand that he pastors a church, he produces some videos, he is involved with the emerging church movement, and some people don't care for his theology. I know he's written a couple of books, his latest with the very provocative title of Sex God. He was in Indianapolis last week for his tour.
UPDATE: Bell has his supporters as well. As with anything, don't just believe other people's words about Bell, positive or negative. Check it out for yourself.
