One other reason, is the gross inefficiencies the Witnesses have in the Ministry. Last count according to the "Year Book", it takes 1000 JWs to bring in one new convert each year, is that the reason your team is so special? "I know we lose a dollar on each widget but if we increase production, we can make it up in volume!" Millions of dollars of gasoline, Starbucks and meals spent for the lowest conversion ratio in religion.
Islam has the highest number of "Forced Converts" in the World. One can't use them as a example since anyone who say's "I don't wish to be a Muslim Dad, will end up getting tortured until they change their thinking."
I will recommend something most JWs don't do, read all the literature and books the slave is providing you. Go to a social website and check out the numbers of growing religions and check if your religion's growth rate is really large. Discount the high number of individuals starting to think and leaving the Organization because they are tired of reading the same material twice a year if not more. You never learn nothing new from the Bible, did you know that the Nahum Chapter 2 is about a Choo Choo Train and a blackman with his red garmet collecting tickets. "Studies in the Scriptures" by brother R. Nahum the prophet from 641 BC saw a vision of a Choo Choo Train? Think that one through, that was your "new light" Jehovah was providing to replace all the Bible Commentaries reasonable remarks of Nahum Chapter 2, now after 100 years the Watchtower Society decided to join the Bible Commentaries explanation instead of using a Choo-Choo Train to explain Nahum Chapter 2.
Taking 100 years to catch up to Christendom's work is not flattering, I think your group is regressing and losing God's Spirit!
