And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years. Revelation 20:1, 2
The revelator foretells the banishment of Satan and the condition of chaos and desolation to which the earth is to be reduced, and he declares that this condition will exist for a thousand years. After presenting the scenes of the Lord's second coming and the destruction of the wicked, the prophecy continues: "I saw an angel come down from heaven, having the key of the bottomless pit."...
Here is to be the home of Satan with his evil angels for a thousand years. Limited to the earth, he will no have access to other worlds to tempt and annoy those who have never fallen. It is in this sense that he is bound: there are none remaining, upon whom he can exercise his power. He is wholly cut off from the work of deception and ruin which for so many centuries has been his sole delight....
For six thousand years, Satan's work of rebellion has "made the earth to tremble." He had "made the world as a wilderness, and destroyed the cities thereof." And he "opened not the house of his prisoners." For six thousand years his prison house has received God's people, and he would have held them captive forever; but Christ had broken his bonds and set the prisoners free. (The Great Controversy, 658, 659)
Reflection: There will have been six thousand years of sin, and now Satan must contemplate during the seventh millennium his work of deception.
