The Antichrist that is coming to fulfill the prophecy of 2 Thess.2, Rev.13:11 forward, Matt.24 and Mark 13, is going to be Satan himself, on earth in person, de facto. It matters not what the world's religions will call him.
Rev 12:7-17
7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
8 And prevailed not; neither was their place found any more in heaven.
That war in Heaven is the Daniel 12:1 event when Michael stands up, and a time of trouble on earth begins that the world has never seen the likes of before, nor will even again. Christ called that time the "great tribulation" in Matt.24. The reason why that time will be one this world has never seen the likes of before, is because Satan de facto, in person, will be cast down to this earth in OUR material dimension. When his place is no longer found in heaven, it means the heavenly dimension. This event has not happened yet, it's still sometime in our near future.
9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
That "dragon" title is specifically a title for Satan himself, and not any other. This was not about his first rebellion against God, because of the tribulation links to this casting down to earth. Not only will he be cast down to this earthly dimension, but his angels will be cast down here also. This is why Rev.11 reveals the beast that ASCENDETH out of the bottomless pit will kill God's two witnesses in Jerusalem after 1260 days. That beast will be Satan himself. His ascension out of the bottomless pit is symbolic for this Rev.12 event of his being cast out of the Heavenly dimension to our earthly dimension. As of right now, his place is the bottomless pit which is IN the Heavenly dimension.
10 And I heard a loud voice saying in heaven, "Now is come salvation, and strength, and the kingdom of our God, and the power of His Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
This verse is how we can be sure this event has yet to happen. When Satan first rebelled, Christ had not yet come to die on the cross. The power of Christ as The Saviour had not yet come back when Satan first rebelled against God. But at this point in time when Satan is cast out of the pit in the Heavenly, down to our earthly dimension, then in Heaven that will be said. Until then, Satan is still in the Heavenly dimension today accusing us before God. His spirit has power to work on this earth today, but he is not here on earth in person, yet. But he is coming, along with his angels.
11 And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
This is yet another time marker for this casting out being specifically for the great tribulation time, and not any other time. This prophecy about those who refuse the image of the beast, and his mark, etc., involves Christ's elect giving a Testimony during the tribulation, and some of them are beheaded for it.
12 Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
Those in the Heavenly will rejoice when Satan is cast out of the Heavenly dimension to the earth. But WOE to the inhabitors of the earth and of the sea. Why? Because Satan is going to come here in person to deceive as many as will, and he knows he has only a short time to do it in, the tribulation time frame. He is the seventh beast king John was shown in Rev.17 that had not come yet. The final Antichrist will be... Satan himself, revealed on earth in our dimension, working great signs and wonders to deceive with.
13 And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child.
14 And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.
When Satan sees that he has been cast to our earthly dimension, he will specifically go after the symbolic 'woman' that represents God's people. God's people will be under His protection for that time, until the time for the delivering up to give a Testimony for Christ.
15 And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood.
16 And the earth helped the woman, and the earth opened her mouth, and swallowed up the flood which the dragon cast out of his mouth.
The water as a flood coming out of that dragon's mouth mean lies to cause deception. This is a metaphor for the deception Satan is going to cause upon the deceived as the "another Jesus" Paul mentioned in 2 Cor.11.
17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
(KJV)
Only a small remnant of faithful believers on Christ Jesus will resist Satan's attempt to destroy them by the false worship of the image of the beast he is going to setup over all the world.
The majority that don't understand this will understand it when Christ returns and they discover who it really was that they bowed in ignorance to.
