What does Revelation 12:10 mean?
Heaven cheers the expulsion of Satan and his angels from heaven. A loud voice from heaven proclaims the fact that the accuser of the believers has been cast down. The voice acknowledges that the accuser points out believers' faults and sins around the clock. Now he is cast out of heaven and God and Christ are exalted.Satan's expulsion brings Christ's millennial kingdom even closer. God will deliver His people from the Devil's tyranny. God's power and Christ's authority are about to be displayed. The end of the Devil's kingdom is certain! Although Jesus judged and defeated the Devil when Jesus was on earth (John 16:11), Jesus did not execute the sentence He pronounced on Satan. Someday, however, He will chain the Devil and cast him into the bottomless pit for a thousand years (Revelation 20:1–3), and finally He will consign the Devil and his followers to eternal punishment in the lake of fire (Revelation 20:7–10).
Revelation 12:7–12 describes a war in heaven which breaks out between Michael and his angels and the Devil. Prior to this expulsion, the Devil has access to heaven, where he accuses believers. Job 1 confirms this fact. However, he cannot prevail in his war on Christ and His followers. Genesis 3:15 prophesies his violent opposition to the virgin-born Son of God, and Revelation 20:1–10 reveals his ultimate defeat and eternal punishment. Revelation 13 unveils the Devil's two henchmen, the beast and the false prophet, who assist him in persecuting Israel.
This chapter relates several highly symbolic visions, which introduce figures critical to the end times. First is a woman, representative of Israel. Second is a red dragon, identified with Satan. Third is a male child, who is Jesus Christ. The red dragon seeks to devour the woman's male child, but God caught the child to His throne, referring to the ascension of Jesus after His resurrection. The passage then continues to describe a war in heaven between Michael and Satan—here Satan becomes the fourth key figure—which results in Satan's complete and total eviction from heaven. Satan attempts to destroy Israel, most likely through an armed invasion, which is supernaturally defeated by God through an earthquake. The fifth main figure is the collective ''offspring'' of the woman. These events are given further details in passages such as Ezekiel chapter 38.
