Jacob teaches his people (at around 559-545 B.C. in the Americas) about the Resurrection being an answer to the Fall.
“…Our flesh must waste away and die; nevertheless, in our bodies we shall see God. Yea, I know that…in the body he shall show himself unto those at Jerusalem, from whence we came; for it is expedient that it should be among them; for it behooveth the great Creator that he suffereth himself to become subject unto man in the flesh, and die for all men, that all men might become subject unto him. For as death hath passed upon all men, to fulfil the merciful plan of the great Creator, there must needs be a power of resurrection, and the resurrection must needs come unto man be reason of the fall; and the fall came by reason of transgression; and because man became fallen they were cut off from the presence of the Lord.” (2 Nephi 9:5-6)
“Wherefore, it must needs be an infinite atonement—save it should be an infinite atonement this corruption could not put on incorruption. Wherefore the first judgment which came upon man must needs have remained to an endless duration. And if so, this flesh must have laid down to rot and crumble to its mother earth to rise no more. O the wisdom of God, his mercy and grace! For behold, if the flesh should rise no more our spirits must become subject to that angel who fell from before the presence of the Eternal God, and became the devil, to rise no more. And our spirits must have become like unto him, and we become devils, angels to a devil, to be shut out from the presence of God, and to remain with the father of lies, in misery, like unto himself…” (2 Nephi 9:7-9)
-What does Jacob mean when he says that Jesus Christ’s Atonement had to be infinite? (for an excellent exploration of this topic read The Infinite Atonement by Tad R. Callister)
-How is being Resurrected with a physical immortal body part of saving our souls from the powers of hell?
-Would remaining as spirits for the eternities after death allow us to reach our full potential as God’s children? In this scenario, could we achieve the same power of spiritual and physical perfection that our Father and Jesus Christ currently have?
-Will the resurrection to a perfected body permanently seal off further spiritual influence from those who will spend eternity without bodies (i.e. Satan and those who followed him in the pre-mortal world)?
-What does it mean to be a subject of Jesus Christ?
Teachings of Latter-day Prophets, Seers, and Revelators:
“If our separation from God and our physical death were permanent, moral agency would mean nothing. Yes, we would be free to make choices, but what would be the point? The end result would always be the same no matter what our actions: death with no hope of resurrection and no hope of heaven. As good or as bad as we might choose to be, we would all end up ‘angels to a devil’ [2 Nephi 9:9]” (D. Todd Christofferson, “Moral Agency,” Ensign, June 2009, 50).
“His Atonement is infinite—without an end. [See 2 Nephi 9:7; 25:16; Alma 34:10, 12, 14.] It was also infinite in that all humankind would be saved from never-ending death. It was infinite in terms of His immense suffering. It was infinite in time, putting an end to the preceding prototype of animal sacrifice. It was infinite in scope—it was to be done once for all. [See Hebrews 10:10.] And the mercy of the Atonement extends not only to an infinite number of people, but also to an infinite number of worlds created by Him. [See D&C 76:24; Moses 1:33.] It was infinite beyond any human scale of measurement or mortal comprehension.
“Jesus was the only one who could offer such an infinite atonement, since He was born of a mortal mother and an immortal Father. Because of that unique birthright, Jesus was an infinite Being” (Russell M. Nelson, “The Atonement,” Ensign, Nov. 1996, 35).
“According to eternal law, that atonement required a personal sacrifice by an immortal being not subject to death. Yet He must die and take up His own body again. The Savior was the only one who could accomplish this. From His mother He inherited power to die. From His Father He obtained power over death” (Russell M. Nelson, “Constancy amid Change,” Ensign, Nov. 1993, 34).
“Just as death would doom us and render our agency meaningless but for the redemption of Christ, even so, without His grace, our sins and bad choices would leave us forever lost. There would be no way of fully recovering from our mistakes, and being unclean, we could never live again in the presence of [God].
“… We need a Savior, a Mediator who can overcome the effects of our sins and errors so that they are not necessarily fatal. It is because of the Atonement of Christ that we can recover from bad choices and be justified under the law as if we had not sinned” (D. Todd Christofferson, “Moral Agency,” Ensign, June 2009, 50).
