2 Nephi 33:1-5

1And now I, Nephi, cannot write all the things which were taught among my people; neither am I mighty in writing, like unto speaking; for when a man speaketh by the power of the Holy Ghost the power of the Holy Ghost carrieth it unto the hearts of the children of men.

2But 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.

3But 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.

4And 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.

5And 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.
