3 But I, Nephi, have written what I have written, and I esteem it as of great worth, and especially unto my people. For I pray continually for them by day, and mine eyes water my pillow by night, because of them; and I cry unto my God in faith, and I know that he will hear my cry.
4 And I know that the Lord God will consecrate my prayers for the gain of my people. And the words which I have written in weakness will be made strong unto them; for it persuadeth them to do good; it maketh known unto them of their fathers; and it speaketh of Jesus, and persuadeth them to believe in him, and to endure to the end, which is life eternal.
5 And it speaketh harshly against sin, according to the plainness of the truth; wherefore, no man will be angry at the words which I have written save he shall be of the spirit of the devil.

I love Nephi’s finally explanation of why his writing is so valuable to his people. He describes the tears he shed in order to write that which would be of most value and he explains his confidence that God will consecrate his efforts.

His work is of value becuase it teaches his people to know of their heritage, speaks to them about Jesus and how we can follow him (through continual faith in him), and finally because it teaches man to avoid sin and therefore evade the snares of the devil.

These truly are the keys to salvation. We must first know who we are and our relationship to God. Next, we must find faith in Jesus Christ, repent, be baptized, by water and fire, and endure to the end. And to do so, we must understand that sin never leads to happiness. We must plainly understand  how to avoid the wiles of the Devil. In other words, Nephi has taught us the Gospel of Christ through his writings. He can therefore rest assured that his words will be consecrated for the good of his people.
