“Resurrection is the reuniting of the spirit with the body in a perfect, immortal state, no longer subject to disease or death (see Alma 11:42–45)” (True to the Faith, 139).
“From the day of the resurrection, the body will develop until it reaches the full measure of the stature of its spirit, whether it be male or female” (Smith, Gospel Doctrine, 24). President Smith also records that “the body will come forth as it is laid to rest, for there is no growth nor development in the grave. As it is laid down, so will it arise” (Smith, Gospel Doctrine, 449).
“President Brigham Young taught that when individuals die they ‘all pass through the veil from this state and go into the world of spirits; and there they dwell waiting for their final destiny’ (Discourses of Brigham Young, p. 376). This world of spirits, as taught by President Young, is very close:
“‘It is not beyond the sun, but is on this earth that was organized for the people that have lived and that do and will live upon it … .
“‘Where is the spirit world? It is right here. Do the good and evil spirits go together? Yes, they do. Do they both inhabit one kingdom? Yes, they do. Do they go to the sun? No. Do they go beyond the boundaries of the organized earth? No, they do not.’ (Discourses of Brigham Young, p. 376; italics added.) …
“The wicked and the righteous live together in the spirit world much the same as they do in mortality, not that the righteous do the things of wickedness, nor that the wicked enjoy the blessings bestowed on the righteous, but that the righteous may preach the gospel to the wicked. If they accept it, they too may lay claim upon the blessings of the Lord through the Atonement. Elder Bruce R. McConkie wrote:
“‘Although there are two spheres within the one spirit world, there is now some intermingling of the righteous and the wicked who inhabit those spheres; and when the wicked spirits repent, they leave their prison-hell and join the righteous in paradise. Hence, we find Joseph Smith saying: “Hades, sheol, paradise, spirits in prison, are all one: it is a world of spirits. The righteous and the wicked all go to the same world of spirits until the resurrection.” (Teachings, p. 310.)’ (Mormon Doctrine, p. 762)” (Doctrine and Covenants Student Manual, 2001, 445).
