"I, Nephi … was taught somewhat in all the learning of my father; … yea, having had a great knowledge of the goodness and the mysteries of God, therefore I make a record of my proceedings in my days."
1 Nephi 1:1
“For behold, thus saith the Lord God: I will give unto the children of men line upon line, precept upon precept, here a little and there a little; and blessed are those who hearken unto my precepts, and lend an ear unto my counsel, for they shall learn wisdom; for unto him that receiveth I will give more; and from them that shall say, We have enough, from them shall be taken away even that which they have.”
2 Nephi 28:30
"Wherefore, the things which are pleasing unto the world I do not write, but the things which are pleasing unto God and unto those who are not of the world. Wherefore, I shall give commandment unto my seed, that they shall not occupy these plates with things which are not of worth unto the children of men."
1 Nephi 6:5–6
“Verily, verily, I say unto you, that this is my doctrine, and whoso buildeth upon this buildeth upon my rock, and the gates of hell shall not prevail against them.”
3 Nephi 11:39
