7 And when the thousand years are ended, Satan will be let loose out of his prison, 8 And will go out to put in error the nations which are in the four quarters of the earth, Gog and Magog, to get them together to the war, the number of whom is like the sands of the sea. 9 And they went up over the face of the earth, and made a circle about the tents of the saints, and the well loved town: and fire came down out of heaven for their destruction. 10 And the Evil One who put them in error was sent down into the sea of ever-burning fire, where the beast and the false prophet are, and their punishment will go on day and night for ever and ever.

The Judgment at the Great White Throne

11 And I saw a great white seat, and him who was seated on it, before whose face the earth and the heaven went in flight; and there was no place for them. 12 And I saw the dead, great and small, taking their places before the high seat; and the books were open, and another book was open, which is the book of life; and the dead were judged by the things which were in the books, even by their works. 13 And the sea gave up the dead which were in it; and death and Hell gave up the dead which were in them; and they were judged every man by his works. 14 And death and Hell were put into the sea of fire. This is the second death, even the sea of fire. 15 And if anyone's name was not in the book of life, he went down into the sea of fire.

Matthew Henry's Commentary on Revelation 20:7-15

Commentary on Revelation 20:7-10

(Read Revelation 20:7-10)

While this world lasts, Satan's power in it will not be wholly destroyed, though it may be limited and lessened. No sooner is Satan let loose, than he again begins deceiving the nations, and stirring them up to make war with the saints and servants of God. It would be well if the servants and ministers of Christ were as active and persevering in doing good, as his enemies in doing mischief. God will fight this last and decisive battle for his people, that the victory may be complete, and the glory be to himself.

Commentary on Revelation 20:11-15

(Read Revelation 20:11-15)

After the events just foretold, the end will speedily come; and there is no mention of any thing else, before the appearing of Christ to judge the world. This will be the great day: the Judge, the Lord Jesus Christ, will then put on majesty and terror. The persons to be judged are the dead, small and great; young and old, low and high, poor and rich. None are so mean, but they have some talents to account for; and none so great, as to avoid having to account for them. Not only those alive at the coming of Christ, but all the dead. There is a book of remembrance both for good and bad: and the book of the sinner's conscience, though formerly secret, will then be opened. Every man will recollect all his past actions, though he had long forgotten many of them. Another book shall be opened, the book of the Scriptures, the rule of life; it represents the Lord's knowledge of his people, and his declaring their repentance, faith, and good works; showing the blessings of the new covenant. By their works men shall be justified or condemned; he will try their principles by their practices. Those justified and acquitted by the gospel, shall be justified and acquitted by the Judge, and shall enter into eternal life, having nothing more to fear from death, or hell, or wicked men; for these are all destroyed together. This is the second death; it is the final separation of sinners from God. Let it be our great concern to see whether our Bibles justify or condemn us now; for Christ will judge the secrets of all men according to the gospel. Who shall dwell with devouring flames?
