There is no 'how for God'. The old farts in Brooklyn ... Walkill ... wherever ... just bend over and pull something out of their butts.
Some 30 odd years ago, I asked both my parents at the same time "Is God directing the Watchtower?"
To me, this is THE question to answer. The reason: it doesn't matter whether the answer is Yes or No, it shows this group is f'ed up and shouldn't be taken seriously at all.
So, at exactly the same time, my Dad answers "No." and my Mom answers "Yes."
You should have seen the "Holy Shiite!" look pass between them. It was priceless. :0)
