The Casting of Satan Out of Heaven To Earth Among Us:
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.
Did you know Satan's and his angel's place is in heaven until this event happens in our near future? Per this event, he is being cast out of heaven down to this earth. What this means about his place not being found in the heavenly anymore is that he is coming to our dimension, here on earth. And I mean 'in person'. He will manifest on earth with the appearance of man, since that's the image God also created the angels with.
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.
Those titles, the Devil, the great dragon, that old serpent, are simply other names for Satan. He has other names than that too, like Abaddon and Apollyon of Rev.9 which means the Destroyer. Not only he, but his angels... are to be cast out with him! Remember Rev.6 about Death on a pale horse and Hell followed with him? "Death" is yet another title for Satan. Hell following with him is symbolic of his angels coming here on earth with him.
If you believe this is just too... fantastic sounding to believe as it is literally written here, then you're already in trouble and are not prepared for what is soon coming upon this earth, and most likely will... be deceived. This is not difficult to understand what our Lord Jesus showed John here. The reader just needs to make up their mind whether they are going to believe it as written or not.
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."
Remember the time of Job, when Satan and his angels appeared before God's Throne in Heaven? Until this event of Satan being cast out of heaven, he presently can come before God's Throne and accuse us like he did Job. Once he is cast out though, that's why this will be said, because he won't be able to do that anymore in heaven. Because this says Salvation is come, and the "power of His Christ", that definitely reveals this event is still future, and did not happen some time back in history. There will be other time markers like later here, like the next verse.
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.
That is a 5th Seal time marker, those that God tells the souls under the altar to wait until they likewise are killed as they were. That is a great tribulation time marker. That even more so let's us know what timing this casting out even is for.
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.
Our Lord Jesus made this plain, "the devil is come down unto you, having great wrath". That's not hard to understand. That "wrath" will be against us in Christ Jesus, His Church. We are not going anywhere before this event; we will... be here. The previous verse was about the overcomers who overcome the Devil by the power of Jesus Christ. That's what our Lord Jesus expects us to do during the tribulation, to overcome it.
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.
Who is this woman? The symbols given at first are about Israel. But later on it's about those who have the Testimony of Jesus Christ, meaning The Gospel, so who do you think that means? That's right, us, Christ's Church. Who is the "dragon" again? The Devil, Satan. During the first part of the symbolic "one week" of Dan.9:27, God's people are protected from Satan's wrath. That's what this verse represents.
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.
This is not a literal flood of water, it's symbolic for LIES that come out of Satan's mouth towards the woman (God's people). But the earth swallowed up the flood out of the dragon's MOUTH. This is all symbolic for Satan coming as the pseudochristos of Matt.24 to play Messiah in Jerusalem. That's the main lie that will come out of his mouth. And that is how... he will do the great signs and miracles in the sight of men, which is about a supernatural working no flesh man could do.
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
In the Book of Daniel, and in Rev.13, we were shown how the Antichrist will go to make war with the saints, and how we will be given into his hand for a short time. This is about the time of "great tribulation" our Lord Jesus warned us about, which are the 7 signs He covered in Matt.24, Mark 13, and in His Book of Revelation.
