Bible: Revelation 20:1-9
The Thousand Year Reign
20:1 Then 1 I saw an angel descending from heaven, holding 2 in his hand the key to the abyss and a huge chain. 20:2 He 3 seized the dragon – the ancient serpent, who is the devil and Satan – and tied him up for a thousand years. 20:3 The angel 4 then 5 threw him into the abyss and locked 6 and sealed it so that he could not deceive the nations until the one thousand years were finished. (After these things he must be released for a brief period of time.)
20:4 Then 7 I saw thrones and seated on them were those who had been given authority to judge. 8 I also saw the souls of those who had been beheaded because of the testimony about Jesus and because of the word of God. These 9 had not worshiped the beast or his image and had refused to receive his mark on their forehead or hand. They 10 came to life 11 and reigned with Christ for a thousand years. 20:5 (The rest of the dead did not come to life until the thousand years were finished.) 12 This is the first resurrection. 20:6 Blessed and holy is the one who takes part 13 in the first resurrection. The second death has no power over them, 14 but they will be priests of God and of Christ, and they will reign with him for a thousand years.
Satan’s Final Defeat
20:7 Now 15 when the thousand years are finished, Satan will be released from his prison 20:8 and will go out to deceive 16 the nations at the four corners of the earth, Gog and Magog, 17 to bring them together for the battle. They are as numerous as the grains of sand in the sea. 18 20:9 They 19 went up 20 on the broad plain of the earth 21 and encircled 22 the camp 23 of the saints and the beloved city, but 24 fire came down from heaven and devoured them completely. 25
