2Nephi 11: 5
In the previous chapter, Nephi's brother Jacob ends with the admonition to choose eternal life or everlasting death. The chapter then states that we must reconcile ourselves to the will of God. It goes on to point out that even doing so still requires the grace of God to be saved. 2Nephi 10: 23-25 emphasis added.
The elements required for "...the eternal plan of deliverance from death" (i.e. salvation) that was received by covenant of the Lord (i.e. Christ see 3Nephi 15:5) to the fathers are His grace, justice, power, and mercy. All of these come by the mission of Christ.
The order in which Nephi arranges these elements is interesting. If I were writing this, I would have put "power" first and "grace" last. I, obviously, am not a prophet who is intimate with Christ, as Nephi and Jacob were. On reflection, none of the elements are either relevant or possible without the grace of Christ. It should come first.
Grace: His grace is the result of the atonement of Christ. Without the atoning sacrifice, justice could never be satisfied, His power would be limited; certainly not adequate to save, and mercy would not be brought to pass. The incomprehensible act brought to us the possibility of life eternal. Because of it justice, an immutable law requiring eternal consequences for every breach of God's laws, could be satisfied by proxy, that is by Christ's suffering for us, then dying and being resurrected.
Power: His power certainly included the power to lay down his life and to take it up again (John 10:18). It was even more, however, because, as is pointed out in 3Nephi 15: 5, for example, He states that He has the power to "...give eternal life."
Mercy: Mercy can now be extended to the faithful who accept the saving ordinances and abide by the associated covenants. Always? We will fall short, of course, but mercy allows for us to repent and by so doing return to the path that leads to eternal life.
Therefore, Nephi goes back to the first element in verse 6, and states that without Christ (implying His willingly accepting the atonement) all men must perish.
Elder Patrick Kearon in our recent Stockholm Stake Conference stated that Christ gives us opportunities for another chance again and again. Then he said, "We must claim them!"
I have heard the advice to claim blessings and have been somewhat uncomfortable with the idea. It seems to imply that because of some degree of personal righteousness we can demand some blessing from God. King Benjamin points out that no matter how righteous we become, we will still be indebted to God because of the blessings received without even qualifying for them.(Mosiah 2:21-25).
Elder Kearon's perspective rings true. There is no greater blessing than repentance because it allows us to obtain eternal life which is the greatest gift of God. I pray for that increased commitment to overcome the lazy, natural man that holds me back from all the promised blessings.
