I like Rob Bell, I found his Nooma series a fantastic tool. Thought provoking and useful as a conversation starter.
Unfortunately Rob Bell has his enemies; I had one person leave our Church with one of the reasons been Rob was heretical. He has probably became more heretical in some people's eyes now with his coming out in support of same sex marriage...
I was encouraged of late when I read Mark Connors blog while not pointing to any doctrinal errors with Rob Bell was happy to quote others and without writing explicitly so keep Rob Bell in the evangelical fold.
Encouraging from one of the biggest names in evangelical Christianity in Australia.
