There is a lot of eschatological events rolled up in this one chapter of Revelation. We start at the second coming of Christ and Satan being bound and placed in the bottomless pit for 1,000 years during Christ’s perfect reign where there will be no direct demonic intervention in the world. Then we have the resurrection of believers who will reign with Christ in the Millennial kingdom. Following the Millennial reign of Christ, Satan is released to bring together the descendants of the believers that survived the tribulation period, who are refusing to believe in Jesus, to fight against Christ and His children in Jerusalem, only to be wiped out by fire from heaven. Worth noting this is God’s final act of wiping out sin from the earth. After this the earth and this universe are destroyed by fire and the unbelievers are resurrected facing the white throne judgement, being cast out into the Lake of Fire forever, the second death, along with Satan. The message is that even without demons, man’s sinful heart wants to rebel against God his Creator to do what is right in his own eyes, and will suffer eternal punishment for it. How blessed are we who realized our humble estate before our God, now called and saved through our faith, believing all that he has told us with our transgressions wiped clean, covered by the blood of His son shed on our behalf. Maranatha!
2 Peter 3:12–13
[12] waiting for and hastening the coming of the day of God, because of which the heavens will be set on fire and dissolved, and the heavenly bodies will melt as they burn! [13] But according to his promise we are waiting for new heavens and a new earth in which righteousness dwells. (ESV)
Revelation 20
The Thousand Years
[1] Then I saw an angel coming down from heaven, holding in his hand the key to the bottomless pit and a great chain. [2] And he seized the dragon, that ancient serpent, who is the devil and Satan, and bound him for a thousand years, [3] and threw him into the pit, and shut it and sealed it over him, so that he might not deceive the nations any longer, until the thousand years were ended. After that he must be released for a little while.
[4] Then I saw thrones, and seated on them were those to whom the authority to judge was committed. Also I saw the souls of those who had been beheaded for the testimony of Jesus and for the word of God, and those who had not worshiped the beast or its image and had not received its mark on their foreheads or their hands. They came to life and reigned with Christ for a thousand years. [5] The rest of the dead did not come to life until the thousand years were ended. This is the first resurrection. [6] Blessed and holy is the one who shares in the first resurrection! Over such the second death has no power, but they will be priests of God and of Christ, and they will reign with him for a thousand years.
The Defeat of Satan
[7] And when the thousand years are ended, Satan will be released from his prison [8] and will come out to deceive the nations that are at the four corners of the earth, Gog and Magog, to gather them for battle; their number is like the sand of the sea. [9] And they marched up over the broad plain of the earth and surrounded the camp of the saints and the beloved city, but fire came down from heaven and consumed them, [10] and the devil who had deceived them was thrown into the lake of fire and sulfur where the beast and the false prophet were, and they will be tormented day and night forever and ever.
Judgment Before the Great White Throne
[11] Then I saw a great white throne and him who was seated on it. From his presence earth and sky fled away, and no place was found for them. [12] And I saw the dead, great and small, standing before the throne, and books were opened. Then another book was opened, which is the book of life. And the dead were judged by what was written in the books, according to what they had done. [13] And the sea gave up the dead who were in it, Death and Hades gave up the dead who were in them, and they were judged, each one of them, according to what they had done. [14] Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. [15] And if anyone’s name was not found written in the book of life, he was thrown into the lake of fire. (ESV)
