You’re close, Po. Jeffress is a Southern Baptist (thank God that he is subject to at least some denominational discipline, though they’re pretty congregational in polity), and they (see item X in their FAQ) are a bit weaselly about the Rapture. They don’t quote the verses you do, but a couple of isolated verses like the old bumper sticker, "Jesus is coming. Look busy,’ and the last chapters in full, the whole denouement of this world. And on their site (I don’t care to look too deeply into Jeffress’s own) there appear to be lively discussions about just what all that means.
The one who really scares me about apocalyptic is Pence. He wanted it to happen on Easter weekend, when he took his wimmenfolk to what he expected to be Ground Zero (oh, I mean “New Jerusalem”). And remember that there are others sprinkled into the West Wing, such as Sarah Huckabee Sanders, a mole for her daddypastor from Arkansas.
Pat Robertson once ran for POTUS specifically to get his finger on the Armageddon controls. Fortunately, he made the mistake of saying so before he could get elected. The scary thing now is that the immature, inexperienced, swaggering djt has advisers with this hidden agenda.
