2. The Binding of Satan

World Scripture

Then I saw an angel coming down from heaven, holding in his hand the key of the bottomless pit and a great chain. And he seized the dragon, that ancient serpent, who is the Devil and Satan, and bound him for a thousand years, and threw him into the pit, and shut it and sealed it over him, that he should deceive the nations no more.
Then I saw a great white throne and him who sat upon it; from his presence earth and sky fled away, and no place was found for them. And I saw the dead, great and small, standing before the throne, and books were opened. Also another book was opened, which is the book of life. And the dead were judged by what was written in the books, by what they had done.
And the sea gave up the dead in it, Death and Hades gave up the dead in them, and all were judged by what they had done. Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire; and if any one’s name was not found written in the book of life, he was thrown into the lake of fire.
Revelation 20.1-15

Teachings of Sun Myung Moon

The Kingdom of Heaven on earth is a restored world in which Satan can no longer instigate any activity. To realize this world, it is necessary for all humanity to eliminate their common base with Satan, restore their common base with God, and engage in give and take action with Him. The prophecy that in the Last Days God will confine Satan in a bottomless pit (Rev. 20.1- 3) signifies that Satan will be utterly incapable of any activity, since there will no longer be any counterpart with whom Satan can relate. In order to eliminate our common base with Satan and be capable of judging him, we must understand the identity and crime of Satan and accuse him before God.
However, God endowed human beings and angels with freedom; therefore, He cannot restore them by force. Of their own free will, human beings are to bring Satan to voluntary submission by upholding the Word of God through fulfilling their responsibility. Only in this way can we be restored to the original ideal purposed by God at the creation.
