Interesting take. Not so sure Satan leaves this planet though. In fact his existence here is strange to begin with, being unseen and all. Perhaps it's a dimensional thing. And maybe we also in some way, exist in dimensions unseen, such as described in Eph. 2:6
There are bits and pieces of said forthcoming event sprinkled into the O.T. What they mean exactly remains cloudy for the moment, but it does tend to get progressively clearer over time:
Isaiah 27:1
In that day
the Lord with his sore and great and strong sword
shall punish leviathan the piercing serpent, even
leviathan that crooked serpent;
and he shall slay the dragon that is in the sea.
Isaiah packs a lot of allegorical punch via associations in the above. As we can also see here:
Ezekiel 29:3-4
Speak, and say,
Thus saith the Lord God; Behold, I am against thee, Pharaoh king of Egypt,
the great dragon that lieth in the midst of his rivers, which hath said, My river is mine own, and I have made it for myself.
But I will put hooks in thy jaws, and I will cause the
fish of thy rivers to stick unto thy scales, and I will bring thee up out of the midst of thy rivers, and all the
fish of thy rivers shall stick unto thy scales.
The prophets opened up the understanding that leviathan, the dragon, the great dragon, the serpent, the great dragon and even Pharaoh(s) are all word associations to SATAN. So we can take that information and dig down ever further, and find for example that the dragon was cut to pieces and fed to PEOPLE:
Psalm 74:13-14
Thou didst divide the sea by thy strength:
thou brakest the heads of the dragons in the waters.
Thou brakest the heads of leviathan in pieces, and gavest him to be meat to the people inhabiting the wilderness.
We also know that the sea and waters are association terms for PEOPLE from Rev. 17:15 and that we collectively live in the wilderness here.
All of these are great avenues of studies for the unseen adversaries that ALL PEOPLE wrestle with. Not even knowing it. Which makes it all a bit strange.
Yeah, well, the above is where most people fall off the cliff on the subject. There will be no person, no man as "thee antiChrist." The antiChrist is Satan. We don't need some guy to be Satan when we all have our own little package of the adversary already installed in our own flesh. Thinking it's some other guy is just another distraction put forth from our adversary.
Scriptures tell us that the beast, the dragon and the false prophet are all SPIRITS OF DEVILS.
There is no need to make any of these characters people, although their words and works are and will be played out in everyone.
God calls us all out of Babylon, and has from the beginning in various ways.
How far we come out in this present life will vary. I believe we all keep one foot in the grave, regardless
