Abdur-Raheem Green shows that Muhammad saws really was receiving revelations from Allah by eliminating the other possibilities: that he was lying about it and that he was mistaken about it.
This reminds me very much of C.S. Lewis's famous "Liar, Lunatic or Lord" argument, and is a nice, logical approach. It would be interesting to hear a longer, more detailed talk that addresses the most obvious objections to Mr Green's argument.
jazakAllah.
I really like Abdur Raheem Green as he understands some of the modern issues Muslims are facing and that he is trying to solve them. His initiative of iERA seems to be a genuine effort and may Allah make it easy for him to reach his goals.
