JC - Chapter 3

As one ponders this chapter, the more one appreciates the Savior, His atonement, and His willingness to do the will of the Father -

"For I came down from heaven, not to do mine own will, but the will of him that sent me."  (New Testament | John 6:38)

"I can of mine own self do nothing: as I hear, I judge: and my judgment is just; because I seek not mine own will, but the will of the Father which hath sent me."  (New Testament | John 5:30)

I note He was willing and only one worthy to make a covenant and take the book (plan of salvation) from the Father as John saw (Revelation 5).

Elder Talmage testified that the Savior was the only being capable to satisfy the requirements of redemption -

"1—As the one and only sinless Man;
2—As the Only Begotten of the Father and therefore the only Being born to earth possessing in their fulness the attributes of both Godhood and manhood;
3—As the One who had been chosen in the heavens and foreordained to this service."

Elder Talmage provides much scriptural references concerning the power of redemption to overcome physical death (for all) and spiritual death (unable to return to the presence of God"  I will only include one that I feel most revealing and truthful -

"...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.
6 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 by 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.
7 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 to crumble to its mother earth, to rise no more.
8 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.
9 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 our God, and to remain with the father of lies, in misery, like unto himself; yea, to that being who beguiled our first parents, who transformeth himself nigh unto an angel of light, and stirreth up the children of men unto secret combinations of murder and all manner of secret works of darkness.
10 O how great the goodness of our God, who prepareth a way for our escape from the grasp of this awful monster; yea, that monster, death and hell, which I call the death of the body, and also the death of the spirit.
11 And because of the way of deliverance of our God, the Holy One of Israel, this death, of which I have spoken, which is the temporal, shall deliver up its dead; which death is the grave.
12 And this death of which I have spoken, which is the spiritual death, shall deliver up its dead; which spiritual death is hell; wherefore, death and hell must deliver up their dead, and hell must deliver up its captive spirits, and the grave must deliver up its captive bodies, and the bodies and the spirits of men will be restored one to the other; and it is by the power of the resurrection of the Holy One of Israel.
13 O how great the plan of our God! For on the other hand, the paradise of God must deliver up the spirits of the righteous, and the grave deliver up the body of the righteous; and the spirit and the body is restored to itself again, and all men become incorruptible, and immortal, and they are living souls, having a perfect knowledge like unto us in the flesh, save it be that our knowledge shall be perfect."  (Book of Mormon | 2 Nephi 9:5 - 13)
