True, but I think only one of them will turn out to be correct.
If you are correct in the sense that it is a literal city which I admit that you could be, it fits Rome much more now and the last several hundred years than it would ever fit Jerusalem.
This is especially so if my understanding of the blood of the saints having to do with communion.
Remember it is called mystery Babylon for a reason, it is not the usual thing.
“...it fits Rome much more now and the last several hundred years than it would ever fit Jerusalem.”
Well, Rome did not kill the prophets. Rome isn’t the city identified as “the great city”. God never promised to pour out the cup of his vengeance on Rome. God never called Rome an adulterous harlot. The antichrist doesn’t set up the abomination of desolation in Rome. The armies of the world do not plunder Rome, treading it underfoot for 42 months. Christ does not land on a mountaintop at Rome upon his return.
However, there is one city that all those things are true of, and all the prophecies of the last days also focus on that city.
