2 Nephi 15

But behold, there are many that harden their hearts against the holy spirit, that it hath no place in them. Wherefore, they cast many things away which are written and esteem them as things of naught. 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, and I know that the Lord God will consecrate my prayers for the gain of my people. And the word which I have written in weakness will he make strong unto them, for it persuadeth men to do good.
