Unit 9: The Second Coming of Jesus Christ
Chapter 44: The Millennium
Concept 2: Who Will Be on Earth during the Millennium?
"Only righteous people will live on the earth during the Millennium. They will be those who have lived virtuous and honest lives. These people will inherit either the terrestrial or celestial kingdom
During the Millennium, mortals will still live on earth, and they will continue to have children as we do now (D&C 45:58 "And the earth shall be given unto them for an inheritance; and they shall multiply and wax strong, and their children shall grow up without sin unto salvation."). Joseph Smith said that immortal beings will frequently visit the earth. These resurrected beings will help with the government and other work. (See Teachings of the Prophet Joseph Smith, p. 268.)
Brigham Young taught that there will be nonmembers of The Church of Jesus Christ of Latter-day Saints living on earth as well as members. People will still have their agency, and for a time many will continue to believe their false religions and ideas. Eventually everyone will accept Jesus Christ as the Savior. (See Daniel h. Ludlow, ed., Latter-day Prophets Speak, pp. 261-62.)
During the Millennium, Jesus will "reign personally upon the earth" (Articles of Faith 1:10). Joseph Smith explained that Jesus and the resurrected Saints will probably not live on the earth all the time but will visit whenever they please or when necessary to help in the governing of the earth (see Teachings of the Prophet Joseph Smith, p. 268).
