In speaking of the Millennium, Nephi explained that “because of the righteousness of [God’s] people, Satan has no power; … for they dwell in righteousness, and the Holy One of Israel reigneth” (1 Nephi 22:26). Moroni stated that one purpose of revealing Satan’s tactics is to do away with evil while looking forward to the time to come when “Satan may have no power upon the hearts of the children of men, but that they may be persuaded to do good continually” (Ether 8:26).
The Prophet Joseph Smith (1805–44) declared: “The devil has no power over us only as we permit him; the moment we revolt at anything which comes from God, the devil takes power” (Teachings of Presidents of the Church: Joseph Smith [2007], 214).
