Christ says two important words here about how to be raised up at the last day—remember His words and do them.
He perceives that some of them are still confused about whether to keep the law of Moses or not, even though He has specifically spelled it out for them. But they’re entrenched in tradition. So, He clarifies once more.
Behold, I say unto you that the law is fulfilled that was given unto Moses. (4)
Behold, I am he that gave the law, and I am he who covenanted with my people Israel: therefore, the law in me is fulfilled, for I have come to fulfil the law; therefore it hath an end.” (5)
Do I ever let myself get so stuck in traditions I have grown up with, that I can’t see truth? That I can’t change when the Spirit whispers for me to do something different than the way I’ve always done it? These people had grown up for centuries with the law of Moses as their religious tradition. And suddenly, Jesus comes and says that law is done away in Him.
I think it’s important for us to work tirelessly to be humble, to ask hard questions of ourselves, so we don’t get stuck in ruts we can’t climb out of. Ask ourselves if we would do certain things (the hardest things we can think of that we would loathe to do) if God or our prophet asked us to do them. If we doubt our ability to change for God, we can work on humility more, repent more, exercise faith in Jesus Christ more. Those simple principles will keep us on a firm foundation, so we are enabled to give our wills to Christ, and do His will.
Jesus further clarifies why the law of Moses has an end in Him.
Behold, I am the law, and the light. Look unto me, and endure to the end, and ye shall live; for unto him that endureth to the end will I give eternal life.” (9)
Christ is everything to us. The light we need to see clearly. The law that pays our debt and brings us back into God’s presence. He is the One who gives eternal life. We can’t just earn our way back to God. Salvation is a gift we claim by following and trusting in Him.
He tells them about other people…”other sheep I have which are not of this fold; them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.” (17)
He is the Lord of all. Jew. Gentile. Bond. Free. All cultures. All races. All that are children of God. Jesus explains that the Nephites/Lamanites were “separated from among them [the Jews of Jerusalem] because of their [the Jews] iniquity.” (19)
The Israelites thought Jesus spoke of the Gentiles when He spoke of other sheep. But the Gentiles never heard or saw Christ in person after His resurrection. They were taught the gospel of Jesus Christ by the Jews, after Christ’s death and resurrection. The Gentiles would not hear Christ’s voice, “save it were by the Holy Ghost.” (23)
Whether we see and hear Christ in person or not, like the Nephites did, we can still be converted to Him through the Holy Ghost. The Spirit will help us remember Christ’s words and do them. And that will make us Christ’s people, heirs of eternal life.
