John sees an angel coming down from heaven with the key to the abyss and a great chain. He seizes the dragon, the ancient serpent, who is the devil and Satan, binds him for a thousand years, throws him into the abyss, shuts it and seals it so that he might not deceive the nations until the thousand years are ended. After that he must be released for a little while (vv. 1-3).
John sees thrones, with those seated on them who were given authority to judge, and the souls of those beheaded for the testimony of Jesus and of those who had not worshiped the beast or received its mark. They came to life and reigned with Christ for a thousand years. The rest of the dead did not come to life until the thousand years were ended. This is the first resurrection. Blessed is the one who shares in it: the second death has no power over them, they will be priests of God and of Christ, and they will reign with him (vv. 4-6).
When the thousand years are ended, Satan is released and goes out to deceive the nations, Gog and Magog, to gather them for battle; they are like the sand of the sea. They surround the camp of the saints and the beloved city, but fire comes down from heaven and consumes them. The devil is thrown into the lake of fire and sulfur, where the beast and the false prophet are (vv. 7-10).
John sees a great white throne and the one seated on it, from whose presence earth and sky flee away. The dead, great and small, stand before the throne, books are opened, and another book, the book of life, and they are judged according to their deeds. The sea, Death and Hades give up their dead. Death and Hades are thrown into the lake of fire, which is the second death, and so is anyone not found written in the book of life (vv. 11-15).
