“And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.
And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, And prevailed not; neither was their place found any more in heaven. 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.
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. 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. 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.
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.”
Revelation 12:3, 7-12, 17
notice the dragon from heaven ( spiritual ) manifests himself in the beast
“And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.”
Revelation 12:3 KJV
“And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy.”
Revelation 13:1 KJV
Later , the beast we see is also colored scarlet ,
“So he carried me away in the spirit into the wilderness: and I saw a woman sit upon a scarlet coloured beast, full of names of blasphemy, having seven heads and ten horns.
...And there are seven kings:
five are fallen,
and one is,
and the other is not yet come;
and when he cometh, he must continue a short space.
And the beast that was, and is not, even he is the eighth, and is of the seven, and goeth into perdition.
And the ten horns which thou sawest are ten kings, which have received no kingdom as yet; but receive power as kings one hour with the beast. These have one mind, and shall give their power and strength unto the beast.”
Revelation 17:3, 10-13
the eighth is in my thinking the one paul was talking about and this really is what I believe we’re seeing in revelation the spiritual view of this subject matter
“Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
Remember ye not, that, when I was yet with you, I told you these things?
For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:
Even him, whose coming is after the working of Satan with all power and signs and lying wonders, And with all deceivableness of unrighteousness in them that perish;
because they received not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, that they should believe a lie:
That they all might be damned who believed not the truth, but had pleasure in unrighteousness.”
2 Thessalonians 2:3-5, 7-12
I believe the dragon , the anti christ ( eighth king ) and the false Church or prophet which some say the other beast who comes from the earth. Is the strong delusion in the world because people refuse to accept and find a love in the gospel
Myself I look at revelation much differently than most people I have discussed it with but again it’s only my own way of thinking
