This has actually been on my mind and wanted to bring up Rev 18 in my thread but you beat me to it! My train of thought was that the collapse of Christian Zionism is too seismic, too consequential within & for Protestantism that something like it would have been prophesied about…to say nothing of the fact that John uses identical language as the Prophet Jeremiah in describing the pronouncements of the angel in Rev 18. (see Jeremiah 50:8, 51:6-8, 51:45).
This is happening in the broader context of people finding their faith again, especially after the covid episode. Obviously we can’t physically see the angels of Rev 14:6-12 and Rev 18 “flying in the midst of heaven and proclaiming in a loud voice…” and yet their movements can be discerned, that this work is underway 9atleast that’s what i believe).
Evangelical pastors themselves are aware that their office/profession is under threat and may not survive. If this planet had another 50yrs, no one will be able to teach this doctrine with a straight face nor will it be accepted because the cost to life & liberty is too great.
