While studying in the book of Revelation, our class read about how during the millenium, Satan will be bound.
1 And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.
2 And he laid hold on the dragon, that old serpent, which is the Devil and Satan, and bound him a thousand years,
3 And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
We talked about how Satan might be bound. We all agreed that the power of God would be able to bind him. But as we studied further, we found some other ways that Satan could be bound.
1 Nephi 22:26
26 And because of the righteousness of his people, Satan has no power; wherefore, he cannot be loosed for the space of many years; for he hath no power over the hearts of the people, for they dwell in righteousness, and the Holy One of Israel reigneth.
Satan only has power over us if we permit him. If we do not give in to his temptations, he will be powerless.
Elder Spencer W. Kimball, then a member of the Quorum of the Twelve said:
"When Satan is bound in a single home—when Satan is bound in a single life—the Millennium has already begun in that home, in that life" ( The Teachings of Spencer W. Kimball, 172).
