Second Nephi 25:26

And we talk of Christ, we rejoice in Christ, we preach of Christ, we prophesy of Christ, and we write according to our prophecies, that our children may know to what source they may look for a remission of their sins.

Nephi and his followers focused their attention on Christ and his central role in the Plan of Salvation. They kept their eyes fixed on the Son of God. We might say that their eye was single (see Matthew 6:22).  It was not that they were not interested in all aspects of the gospel. But they recognized that everything in the gospel pointed them back to Christ.

This is a truth that the Jews missed. They studied and kept the Law of Moses for the law's sake. They failed to see that the law was merely a means to an end, the end being the salvation through Christ. They thought that they could save themselves through strict obedience. They missed the fact that perfect obedience is an illusion for mortal man.

Latter-day Saints sometimes fall into the same trap. We emphasize keeping the commandments, and there are lots of commandments to keep. We cannot afford to miss the fact that we all fall short of the glory of God (see Romans 3:23). We miss the fact that we keep the commandments not to earn our way into heaven, but to practice being like Christ so that we can be comfortable in his presence. It is the Christ and his Atonement, and not our imperfect works, that will save us in the Kingdom of God.
