There are no apologists on this board. Most true JWs, unfortunately, only stick their heads up to post, then dive and run silent before the destroyers can reach them.
The God of the Old Testament is Jehovah, who was born into mortality as Jesus. Jehovah is the Son, not the Father. Their confusion on that issue alone is a minefield that sinks many of them. Still, if they understood the scriptures, they would recognize that. They also believe the Earth will exist as it did in its Edenic state instead of being resurrected as a fiery sphere of replendent glory. Even as the saints were baptized by water and fire (the Holy Spirit), the Earth will die and be resurrected, having been baptized by a flood and cleansed by fire. Ask a JW sometime what joy will come after six months of Edenic pleasures. How fun can petting tigers be after a few weeks?
After 787 family reunions, one each week, I suspect mahem would break out as people attacked each other with guitars and pitchforks! And after all the children grew up, what happiness would exist after that. "Hey, Melrose, a bunch of us are going over and pet the tigers next Tuesday. Want to join us?" The giant cats would eat grain during the day, but some of the more astute Witnesses would start noticing goats and sheeps missing in the mornings. Then they'd notice the cats would be less interested in the wheat the next day. Then some of them would begin disappearing.
But then, you won't read about that in any of the pamphlets!
