UPDATE 20 September 2017: Up to this point Eschatology Today has deliberately concentrated on Revelation 12:1-2. The reasoning is simple. The sign in these first two in-progress verses are separate from the second, or "another" sign which follows in verse three. They are set apart and distinct signs in both time and place.
The first sign has been taking shape in the heavens over the past nine months and concludes this Saturday. This sign will not occur again in the future. Scripture tells us, as also already touched upon, that the heavens shall be shaken, heavenly bodies in space, planets and stars, will be moved from their places by the power of God. This appears to occur no later than the middle of the 70th Week.
Therefore, a near future occurrence of this very unique astronomical alignment in Leo and Virgo would be preempted from ever occurring again in the future. With this shaking and moving of the heavenly bodies the constellations themselves will likely be completely altered. The constellations only exist as seen from the earth in the night sky and nowhere else. It seems obvious that at the time of their shaking and moving they will have completely fulfilled the Lord's anointed purpose as signs. A new heaven will exist in the future. Therefore, first sign of Revelation 12:1-2 is entirely exclusive to the present time, right here, right now.
The second sign, Revelation 12:3, as mentioned briefly in previous posts, is a picture of the Antichrist in the form of his completed earthly kingdom, the fourth beast kingdom consisting of seven heads and ten horns. The second sign of Revelation 12:3 then is clearly a picture of an earthly realm as is made crystal clear by reading in context the entirety of Daniel 7.
In Daniel 7 we read that the fourth and final beast begins as ten, but is reduced to seven when Antichrist, the eleventh rising little horn among them, subdues three of the kings (horns) among the ten, rips their horns out by the roots to place them upon his own head. Therefore verse three is a literal event which occurs at the start of the 70th Week. Without question the Bride of Christ will have been taken from this earth prior to the occurrence of the sign of Revelation 12:3. As can be seen in Revelation 12:6 this period of time is without any doubt the second half of the 70th Week, the great Tribulation as some refer to it; the Megas Thlipsis as Jesus referred to it in His discourse on the Mount of Olives.
We may as well also now look at Revelation 12:7-17. These verses are a type of recap of the events described in the sum of the previous verses. Give great attention to verse seventeen as it describes the woman from verse one as also having other offspring. At this period of time during the Megas Thlipsis these other offspring of the woman can only be the innumerable Saints of the 70th Week - those who have received Salvation by the Blood of the Lamb through the testimony of the 144,000 Jewish priests who had the seal of the living God placed upon their foreheads in Revelation 7.
