John Cedars' YouTube Channel has a new video interview with James Penton. Lloyd asks some good questions and Jim provides excellent insights about JW history and where the movement may be headed.
I had the pleasure of meeting Jim and his former wife, now passed away, at the Christian Believers Conference (of Bible Students). http://www.cbconference.com/
I've also read his books and I'm very impressed with the research he's done.
I highly recommend watching the interview.
