Those Rev.12:7-17 verses DID NOT HAPPEN at the cross. Those events ARE STILL FUTURE, and very soon to come at the end of this world.
Not true. Revelation 12 places the defeat of Satan at the resurrection/ascension:
"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."
Previous to Satan's eviction, God was Israel's God, not the Gentiles God. Satan ruled the nations. But through this casting out of Satan, after man's penalty had been paid in full, he no longer had anything to accuse the elect over. It was indeed finished! The powerful spread of the Gospel to the Gentiles lifting the deception that kept them bound. Satan was now bound. The boot was on the other foot. With the global expanse of the great commission the Gentiles now are without excuse. The ignorance is gone. The veil is lifted. The means by which God lifts deception is the preaching of the Word of God. This has now been successfully ongoing throughout the nations for 2000 years.
Satan's defeat came through His sinless life, His atoning death and His glorious resurrection. Here is when He got His eviction notice, and here is "when" salvation came to the "whole world" - not just one nation Israel. The deception enveloping the Gentiles was lifted - praise God. They are now without excuse, just like those in the OT that rejected salvation. Salvation has now come to the nations. But Satan had to first be cast down. He had to be defeated. Christ’s life, death and resurrection safely secured that. As a result, the Church becomes a militant overcoming organism.
Christ predicted shortly before He destroyed the power of Satan at the cross, in John 12:30-33:
“Now is the judgment of this world: now shall the prince of this world be cast out. And I, if I be lifted up from the earth, will draw all men unto me. This he said, signifying what death he should die.”
Christ’s death, burial and resurrection were the decisive blows against Satan. His defeat has already been wrought. This passage plainly shows the powerful result of Calvary and the deep impact it had upon Satan. It shows us that Satan is now under Christ’s feet and is now subject to His Sovereign will. Satan and his minions are barred from heaven. They have been banished after they were defeated 2,000 years ago.
Before being cast out of heaven through Christ’s victorious assault on his kingdom the devil had access to both heaven and earth. He had the ability to come before God to accuse the brethren of their sins. When he was cast down he no longer had access to heaven but only to earth.
Revelation 12:11 tells us that
“they (the Church)
overcame him (Satan)
by the blood of the Lamb, and by the word of their testimony.” Satan can be overcome in this life.
Satan is curtailed when the Church operates in and under the anointing and authority of the Lord Jesus Christ. Christ’s life, death and resurrection have opened the door and bust the devil aside. As ambassadors of another nation (a more powerful heavenly nation), we have been given authority over the devices of the enemy. We can defeat in our lives and through the spread of the Gospel.
