The following is a rough sketch of the chronology of the events of Armageddon. First, Armageddon is not a battle but a series of battles that covers most of the second half of the tribulation, known as the Great Tribulation
End time eschatology is my calling of 40 years. I will take these point by point, its all good to offer a guess, but its better to be in the know. You have the pre trib. correct and the Day of the Lord is nor one day but 1260 days, so you are spot on there. But Armageddon is simply the marriage supper back on earth, we revel in our victory, and Jesus defeats them by the presence of his coming, thus is no battle in reality.
1. The Antichrist summons all his allies to prepare for war, the Antichrist becomes world dictator at this time
The AC will not rule the whole world , I can back this up wit scriptures, no Beast over Israel ever ruled the whole earth, even though Daniel 2 says that Nebuchadnezzar & Greece was said to rule the whole earth, but why? Because these Beasts all arose out of the Great Sea (The Mediterranean Sea) and they are about a POWER that rules over Israel and a defined region around that lone sea. The earth being spoken of in each case is the land around the Mediterranean Sea. How is the AC (E.U. leader) going to rule over China & Russia who have n Nukes? The USA an d the New World imho, is the 1/3 that gets wiped out by the Rev. 8 Asteroid and Fires it brings, why would God destroy the Old World when Jesus is going to rule from Jerusalem for 1000 years? The New World has 1/3 of the worlds Landmass and the Pacific Ocean covers 1/3 of the earth. His lone goal is to kill every Jew proving God a liar.
2. They attack Babylon and it is destroyed
Babylon is a DEAD CITY, God uses Babylon for the WHOLE WORLD. I wrote a blog on this 8 or so years back, I was citing Rome as THAT CITY in vs. 18 (Rev. 17:18) and the holy spirit was like Ron, look again at only what John SAWEST !!, and once I did, I realized the vision was only 4 verses long (3-6) and the City Babylon was being used to describe "The Harlot" like this:
MYSTERY (Secret heretofore or question mark)
1.) Babylon the Great (Babylon was world renowned for
FALSE RELIGION)
2.) Mother of Harlots (
FALSE RELIGION was the original Harlotry against God)
3.) Abominations of the Earth (God is a jealous God and He hates all
FALSE RELIGION)
In vs. 7 the Angel says come and I will show you the MYSTERY of the Harlot (False Religions) and the [Government] Beasts she rides, its always been False Religion and False Governance cojoined at the hip until the Beast JUDGES the Harlot in Rev. 17:16 but why will it be different at that point in time? Because unlike the other Beasts who worshiped false gods, this man will think he is GOD!! Thus he will kill off all False Religions, be it Witch Craft, Islam, Buddhism, Hinduism, et al. as well as kill off those gentile Christians who repent after the Rapture.
In olden times a harlot was sent to the city square, and her clientele would look for a name tag on her forehead (highest point). Here, God TAGS this Harlot with Three Identifiers. We have to figure out what this mystery is pointing unto by the clues God gives us.
Rev. 18 is Babylon (whole world) being judged by God, you see False Religion is Judged in Rev. 17 via God using the AC and his 10 kings (EU) to do His biding, then God Himself judges Babylon. Rev. 16:19 identifies Babylon as the WHOLE WORLD, it says God remembered Babylon the Great when His wrath fell as Jesus wipes them all out, so Jesus wiped out Babylon, so who were they? Well, lets look back to Vial #6 where it says the Kings of the WHOLE WORLD prepared t go to battle against Almighty God. So, we know Babylon equals the WHOLE WORLD under Satan's Dark Kingdom of Babylon or Deception. In Rev. 18:2 we see Babylon(world) has fallen and become a habitation of DEVILS but why? Because Satan has been cast down to earth at the midway point and the demons from the pit released.
Getting log, better post and finish later.
