"We are back at the birth of Christ" they will say. I no longer agree with that assumption, but even if John is seeing Signs that represent some already past events. I believe these Signs will one day be seen in the Heavens, not just by John but by everyone. Luke 21:25 foretells "And there shall be signs in the sun, and in the moon, and in the stars".
Matthew and Mark has Jesus refer to "The Sign of The Son of Man" being seen in the Heavens. I have two theories on what that correlates to in Revelation. One I've said before is the Ark being seen in the Heavenly Temple in Revelation 11. But another option is perhaps the Signs John sees in Revelation 12, the Birth of the Son of Man/Seed of The Woman.
Again, both the Chapter and Verse divisions are not in the original text. If you read Revelation from the sounding of the 7th Trumpet on till when The Dragon is cast down without letting the man made divisions effect your perception, I don't think it's possible to fail to see they're all one continuous sequence of events. I will provide an easy way to do that at the end of this post.
Revelation 12:1 in the Greek text begins with Kai, Kai is translated in the KJV "and there" but in fact "and then" would be more accurate here, the word is translated "then" elsewhere in the KJV often. It's also the exact same word that begins 12:3. That word is how many verses in Revelation begin, including the last to chapter 11 and all of them in chapter 12 and most in 12.
Some defending the idea of Revelation starting over and showing us the same events from a "different angle" mention that we have Four Gospels, and that Chronicles repeats much of the history from Samuel and Kings.
Those are different books. And when we do see different events from different angles within the same book on the subject of prophecy they're defined as distinct separate visions, usually given at different times. Like the many visions Daniel has (or interprets for others). And I indeed do believe we see most of what's in Revelation from different angles in other Prophetic books.
Revelation however is one continuous vision. John was taken out of the Earth to the Heavenly Throne Room and is walked through everything that will happen step by step. Revelation ceases to be confusing when people just accept that and interpret other Bible Prophecies chronology based on where John explicitly identifies them in Revelation. Including that when the Son of Man comes on a cloud is in Revelation 14.
Even if some start over were the case, we're clearly caught up to the midway point and the Abomination of Desolation when The Woman flees as synchronization with Matthew 24 shows. Her time in the wilderness is clearly the second half not the first. It's generally the desire to justify putting the Trumpets in the second half that comes from this specific start over theory. I've dealt elsewhere with why the Trumpets and Bowls being concurrent doesn't work.
The second woe is past; and, behold, the third woe cometh quickly.
And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever. And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God, saying, "We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned. And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth." And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
And then a great wonder appeared in heaven; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars: And she being with child cried, travailing in birth, and pained to be delivered. And then appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads. And his tail drew the third part of the stars of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born. And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne. And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days.
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."
