I believe Jehovah has been refining his people through out the years, since 1919. Abusive elders have been removed and disciplined when necessary. Some have gotten away with their ill treatment of Jehovah's sheep and they will receive his judgement. Others were abusive at one time and through counseling from C.O. and other elders, have changed.
Sure, brothers have done that under God's direction. I can see that. But, that doesn't seem to be what Ezekiel 34 is foretelling. Jehovah's judgment upon the bad shepherds is total. There won't be any left in positions of responsibility once Jehovah acts. Otherwise, we would have to assume that Jehovah failed to accomplish what he foretold since there are undeniably such ones presently serving. We will find out exactly how Jehovah will accomplish what he wills. It's a great time to be one of Jehovah's Witnesses. Things are starting to get interesting. / You Know
