About 30 years ago, I asked both my parents at the same time the following question:
"Is God directing the Watchtower?"
At exactly the same time, my Dad answers "No." and my Mom answers "Yes."
You shoulda seen the "Holy Shiite!" look that passed between them. It was priceless.
You see to me, this is THE essential question. It doesn't really matter whether the answer is Yes or No because either answer nullifies the authenticity of this group.
If the answer is "Yes" this flows into a whole line of questioning about why God keeps changing the truth with 'nu lite'. If you claim to have truth about something but then change this understanding, you certainly didn't have truth to begin with. And this leads to questioning the organization having truth now and why God just can't give them the truth to begin with. One can only conclude God is f'ing with them and/or this group is so dense they can't understand what God is saying to them. I, for one, am uninterested in belonging to any group that God wants to treat this way and/or that these leaders are so incompetent that they can't understand a thing being 'said' to them and can't get anything right the first time.
If the answer is No, then what's the point in following this group? They are just another religion with their hand in your wallet, making you feel like crap because you can never do enough for them. And God is certainly NOT with them.
