I would disagree on that. I say the war in Rev 12 is past. Jesus saw satan falling from heaven in the gospel of John, which matches the description in Rev 12.
Plus Rev 12 has the birth of Jesus being described, its clearly 1st century history, which continues on as the dragon wages war upon the saints even till this day.
The heavenly war described in Revelation chapter 12 is definitely not past. Again, when it takes place, it will be the fulfillment of what Daniel prophesied here.
Dan 12:1
And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.
Dan 12:2
And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame
and everlasting contempt.
Dan 12:3
And they that be wise shall shine as the brightness of the firmament; and they that turn many to righteousness as the stars for ever and ever.
Dan 12:4
But thou, O Daniel, shut up the words, and seal the book,
even to the time of the end: many shall run to and fro, and knowledge shall be increased.
Dan 12:5
Then I Daniel looked, and, behold, there stood other two, the one on this side of the bank of the river, and the other on that side of the bank of the river.
Dan 12:6
And
one said to the man clothed in linen, which
was upon the waters of the river, How long
shall it be to the end of these wonders?
Dan 12:7
And I heard the man clothed in linen, which
was upon the waters of the river, when he held up his right hand and his left hand unto heaven,
and sware by him that liveth for ever that it shall be for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these
things shall be finished.
In verse 1, we see the archangel Michael, the great prince who stands for the children of Israel, stand up, and at that time, there will be a time of trouble (the great tribulation) such as never was since there was a nation, even to that same time. Furthermore, in verse 7, Daniel is told the duration of the great tribulation, and it is for a time, times, and an half, or it is a timeframe of 3 1/2 years, and this is precisely the timeframe that is being described in relation to the war in Revelation chapter 12.
Rev 12:6
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.
Rev 12:7
And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
Rev 12:8
And prevailed not; neither was their place found any more in heaven.
Rev 12:9
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.
Rev 12:10
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.
Rev 12:11
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.
Rev 12:12
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.
Rev 12:13
And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man
child.
Rev 12:14
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.
In verse 7, we see the same archangel Michael standing up for the children of Israel (the woman in verses 6, 13, and 14) that we saw standing up in Daniel 12:1.
In verses 6, 12, and 14, we see the same exact "short time" of great tribulation, or the same exact "short time" of Satan's great wrath, and it is a timeframe of "a thousand two hundred and threescore days" (3 1/2 years), or "a time, and times, and half a time" (3 1/2 years), or the same exact "time, times, and an half" (3 1/2 years) that we read about in Daniel 12:7.
What Jesus described in Luke 10:18 (not in the gospel of John), has absolutely nothing to do with what I just accurately described here.
