Devil and His Armies Cast Out Eternally

Revelation 20:7-9; 7-9. Before the millennium, Gog and Magog—that combination of nations from the lands of the north, who opposed the Lord and his purposes and people—were overthrown by the coming of the God of Battles to reign personally upon the earth. (Ezek. 38 and 39.) After the millennium—plus a little season to allow the forces of evil to gather their numberless hosts, this time from the four quarters of the earth—Gog and Magog again shall array themselves against the Lord and his saints; and then shall come the final overthrow of the devil and all his evil devices.

Revelation 20:7-9; "When the thousand years are ended, and men again begin to deny their God, then will I spare the earth but for a little season; And the end shall come, and the heaven and the earth shall be consumed and pass away, and there shall be a new heaven and a new earth." (D&C 29:22-23.)

Revelation 20:7-9; "Satan shall be bound, that old serpent, who is called the devil, and shall not be loosed for the space of a thousand years. And then he shall be loosed for a little season, that he may gather together his armies. And Michael, the seventh angel, even the archangel, shall gather together his armies, even the hosts of heaven. And the devil shall gather together his armies; even the hosts of hell, and shall come up to battle against Michael and his armies. And then cometh the battle of the great God; and the devil and his armies shall be cast away into their own place, that they shall not have power over the saints any more at all. For Michael shall fight their battles, and shall overcome him who seeketh the throne of him who sitteth upon the throne, even the Lamb. This is the glory of God, and the sanctified; and they shall not any more see death." (D&C 88:110-116.)

Revelation 20:10; 10. "They who are righteous shall be righteous still, and they who are filthy shall be filthy still; wherefore, they who are filthy are the devil and his angels; and they shall go away into everlasting fire; prepared for them; and their torment is as a lake of fire and brimstone, whose flame ascendeth up forever and ever and has no end." (2 Nephi 9:16.)
