Some core problems with that whole Watchtower as I see them:
1. There is no reason why the issue should still be in existence, particularly the part about mans loyalty to God. If you take the Scientific principle of falsification, then you only need one example to prove a theory wrong. If Satan challenged that NO-ONE would worship God under test then one example, Job, was all that was needed to disprove that. Issue settled, lets move on! If we needed a perfect man, then Jesus proved it wrong. Issue done and dusted. Why another 2,000 years and thousands more cased needed? They are not.
2. The whole concept of Sovereignty issue more important than personal salvation thing suggests God is a selfish being, more concerned with his own problems than his children's. If God truly lives by his own principles, such as "be more interested in serving the needs of others than your own" then surely it should be the other way around?
3. They are claiming a divine appointment they have admitted they do not have. In the recent doctrinal changes it was stated that the F&DS do not receive their appointment over the Masters belongings until the Great Tribulation, a future event. So for the time being they have only been authorised to "feed" the household, they have not been authorised or appointed to "direct" the household. So they are acting presumptuously, the very sin they claim to hate, the most in asking us to obey this divine authority.
