Mud on the wall, DD. In the Book of Revelation (as I remember)...there was verse alluding to a 'new covenant', which I ASSUMUMED would be an 'updating' of sorts. Words...communication...ideas. Foggy glass.
Anyway, we'll get scolded for Theology here, that don't relate to politics. Not that theology doesn't always relate to politics and morality.
Of course it makes perfect sense for God (assuming again) to 'update' His communication to the kids. Even Jesus spoke of things he would not speak to the Disciples back then; would only have confused them. "Many mansions" = parallel universes. That theory alone, explains A TON of philosophical problems re Theology, Science and Morality.
Any way...it you are a 'Bible thumper'...I wouldn't get antsy. There will be plenty of preparatory talk...but any real and absolute (only for them who take the leap of Faith) conclusions will come AFTER the Second Coming. The Spiritual version. No guy with long hair riding in from the sky on a horse
...just pure, clear, comforting and inspiring VISION OF TRUTH.
