The word of God is priceless, for it conveys the law that God would have us follow. Nephi’s inward conviction about the essential nature of the scriptures points us forward several centuries to the time that King Benjamin, holding in his hands the very plates of brass brought by Nephi under commandment of the Lord, instructs his sons on these same principles:
And he also taught them concerning the records which were engraven on the plates of brass, saying: My sons, I would that ye should remember that were it not for these plates, which contain these records and these commandments, we must have suffered in ignorance, even at this present time, not knowing the mysteries of God.
For it were not possible that our father, Lehi, could have remembered all these things, to have taught them to his children, except it were for the help of these plates; for he having been taught in the language of the Egyptians therefore he could read these engravings, and teach them to his children, that thereby they could teach them to their children, and so fulfilling the commandments of God, even down to this present time.
I say unto you, my sons, were it not for these things, which have been kept and preserved by the hand of God, that we might read and understand of his mysteries, and have his commandments always before our eyes, that even our fathers would have dwindled in unbelief, and we should have been like unto our brethren, the Lamanites, who know nothing concerning these things, or even do not believe them when they are taught them, because of the traditions of their fathers, which are not correct.
O my sons, I would that ye should remember that these sayings are true, and also that these records are true. And behold, also the plates of Nephi, which contain the records and the sayings of our fathers from the time they left Jerusalem until now, and they are true; and we can know of their surety because we have them before our eyes.
And now, my sons, I would that ye should remember to search them diligently, that ye may profit thereby; and I would that ye should keep the commandments of God, that ye may prosper in the land according to the promises which the Lord made unto our fathers (Mosiah 1:3–7).
