The Resurrection brings about the restoration of the mortal body to an immortal state. Elder Bruce R. McConkie provides the following details concerning the Resurrection:
This doctrine of a universal resurrection was known and taught from the beginning… . (see D. & C. 29:42–50; Moses 5:6–15.)
Christ was the firstfruits of the resurrection (1 Cor. 15:23), and because of his resurrection, “by the power of God,” all men shall come forth from the grave. (Morm. 9:13)… .
To those who lived before the resurrection of Christ, the day of his coming forth from the dead was known as the first resurrection. Abinadi and Alma, for instance, so considered it. (Mosiah 15:21–25; Alma 40.) To those who have lived since that day, the first resurrection is yet future and will take place at the time of the Second Coming. (D. & C. 88:96–102.) We have no knowledge that the resurrection is going on now or that any persons have been resurrected since the day in which Christ came forth excepting Peter, James, and Moroni, all of whom had special labors to perform in this day which necessitated tangible resurrected bodies.
Though all men are assured of a resurrection, all will not be resurrected at the same time, and there will be varying degrees of glory for immortal persons. All will come forth from the grave, “But every man in his own order” (1 Cor. 15:23), as Paul expresses it. Joseph Smith said: “In the resurrection, some are raised to be angels, others are raised to become gods.” (Teachings, p. 312.) (Mormon Doctrine, 2d ed. [Salt Lake City: Bookcraft, 1966], 638–639)
