I recently discovered a great book which I would like to recommend. It is called A PEOPLE FOR HIS NAME and it was written by a Jehovah's Witness named Timothy White. I love this book and it helps one to see the origins of many things taught by the witnessing such as disfellowshipping and the blood doctrine.
This book was published in 1967 and it is interesting that back then White notes:
Finanlly, a prophesy by one of Jehovah's Witnesses that has come true!
One thing is certain:
The Witnesses have shown no disposition to stop “advancing in the light” as they call all changes. And if the King of the North has changed from Napoleon to Hitler to the Communists, we might well expect it to change to someone else when the Cornmunists are no longer a threat. Whatever may be taught in the future, we may be sure the Witnesses will dutifully accept it without a blush or a blink, and continue preaching the nearness of the end.
