Revelation 12:7-9

Verse 7-9 "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"

Now (in this "string on the guitar" or history of the conflict between Israel/Christ and Satan) we have reached the midpoint of the 70th week where the woman flees, as the armies encompass Jerusalem. Simultaneously while this and the abomination of desolation are happening on earth, we see that war breaks out in heaven. Michael and his angels war with Satan and his fallen angels, and Satan and his group get thrown out of heaven. Most people do not realize that they still have access to heaven. One only needs to read the book of Job to see that Satan spends a great deal of time there accusing us before God. As he is not the only one doing the accusing (he is not omnipresent to know what everyone is doing), others of his followers must be doing the same. Now they are cast out of heaven once and for all. They will never be allowed access to heaven again. In Daniel 12 we read that Michael stood up and there was a time of trouble such as the world had never seen before. At that time it was seen from the definition, that he stands back and does nothing during the tribulation. However, before he stands back and just has to watch Satan take out his wrath on mankind, Michael (who is Satan's adversary in the angelic realm) gets very active and fights Satan. Once this rabble is thrown out of heaven, Michael has to stand back and just watch what happens next. Satan is thrown out of heaven and down to the earth. This is bad news for the earth. He is mad and he is going to get even. This is why this time of great tribulation is going to be unparalleled in all of history. It will be Satan with the restrainer removed from hindering him. It will be his last hurrah. He will do his best to eliminate all of mankind, and eliminate the planet entirely if it were possible. It is his last ditch attempt to render God incapable of fulfilling his promise of a kingdom on earth with Israel as the reigning nation, which would make Satan the winner, if he could do it. Of course he cannot, but the damage will be beyond comprehension.
