Revelation 20

Revelation 20 describes an angel binding Satan for a thousand years, during which time martyrs and faithful saints reign with Christ in the first resurrection. After this millennium, Satan is briefly loosed to deceive nations, leading to a final battle where he and his followers are destroyed by divine fire. The chapter concludes with the Great White Throne Judgment, where all the dead are judged according to their works, and those not found in the Book of Life are cast into the lake of fire, which is the second death.

An angel descends, binding Satan, the ancient serpent, for a thousand years in the bottomless pit, preventing him from deceiving the nations. During this period, those martyred for Christ and those who rejected the beast's mark are resurrected in the "first resurrection" and reign with Christ for a millennium. Upon the completion of these thousand years, Satan is released for a brief season, gathering vast armies from the nations, identified as Gog and Magog, to attack the camp of the saints and the beloved city. Divine fire consumes these forces, and Satan himself is cast into the lake of fire, joining the beast and false prophet for eternal torment. Following this, the Great White Throne Judgment commences, where the heavens and earth flee from God's presence. All the dead, from every place, are resurrected and judged according to their deeds recorded in books, with the Book of Life also being opened. Finally, death and hell are cast into the lake of fire, which is the "second death," and anyone whose name is not found in the Book of Life suffers the same fate.

The twentieth chapter of Revelation opens with the vision of a mighty angel descending from heaven, holding the key to the bottomless pit and a great chain. This angel seizes the dragon, identified as the old serpent, the Devil, and Satan, binding him for a period of a thousand years. He is then cast into the bottomless pit, sealed away to prevent him from deceiving the nations until the thousand years are fulfilled, after which he is destined to be loosed for a short season. Following this, the apostle John beholds thrones upon which individuals are seated, to whom judgment is committed. He specifically sees the souls of those who were beheaded for their testimony of Jesus and the word of God, and those who had not worshipped the beast or its image, nor received its mark. These individuals are described as living and reigning with Christ for a thousand years, marking what is termed the "first resurrection." The text explicitly states that the rest of the dead do not live again until the thousand years are finished. A blessing is pronounced upon those who participate in this first resurrection, declaring that the second death has no power over them, and they shall serve as priests of God and of Christ, reigning with Him for the full millennium. Upon the expiration of the thousand years, Satan is loosed from his prison, immediately going forth to deceive the nations across the earth, specifically Gog and Magog, gathering them for a final battle. Their number is vast, likened to the sand of the sea. They ascend upon the breadth of the earth and surround the camp of the saints and the beloved city, but fire descends from God out of heaven and devours them. The devil, who orchestrated this deception, is then cast into the lake of fire and brimstone, where the beast and the false prophet already reside, to be tormented day and night for ever and ever. The vision then shifts to the Great White Throne Judgment. John sees a majestic white throne and Him who sits upon it, from whose presence the earth and heaven flee away, leaving no place for them. All the dead, both small and great, are seen standing before God. Books are opened, and another book, the Book of Life, is also opened. The dead are judged according to their works as recorded in these books. The sea, death, and hell surrender their dead, and every person is judged according to their deeds. Finally, death and hell themselves are cast into the lake of fire, which is explicitly identified as the "second death." The chapter concludes with the solemn declaration that whosoever's name was not found written in the Book of Life was also cast into the lake of fire.
