“The ‘redeemed of the Lord’ who were to ‘return, and come with singing unto Zion’ with ‘everlasting joy’ are identified in the Doctrine and Covenants as the Latter-day Saints (see D&C 45:71; 66:11; 101:18). The return has begun, but it will not be completed until the center place of Zion is built up ‘that the prophets might be fulfilled’ (D&C 101:19)” (Nyman, Great Are the Words of Isaiah, 196).
The Prophet Joseph Smith taught that during the Millennium, “the earth will be renewed and receive its paradisiacal glory” (Articles of Faith 1:10).
“During the Millennium, Satan will be bound. This means he will not have power to tempt those who are living at that time (see D&C 101:28). The ‘children shall grow up without sin unto salvation’ (D&C 45:58). ‘Because of the righteousness of [the Lord’s] 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’ (1 Nephi 22:26)” (Gospel Principles, 265–66).
