Paul,
I am certainly familiar with 1 Nephi 13 and 2 Nephi 29 about “plain and precious truths” having been lost from the Bible that goes forth according to prophecy and is accepted as “sola scriptura” according to prophecy. There are also these verses:
2 Nephi 29:3 And because my words shall hiss forth—many of the Gentiles shall say: A Bible! A Bible! We have got a Bible, and there cannot be any more Bible.
4 But thus saith the Lord God: O fools, they shall have a Bible; and it shall proceed forth from the Jews, mine ancient covenant people. And what thank they the Jews for the Bible which they receive from them? Yea, what do the Gentiles mean? Do they remember the travails, and the labors, and the pains of the Jews, and their diligence unto me, in bringing forth salvation unto the Gentiles?
5 O ye Gentiles, have ye remembered the Jews, mine ancient covenant people? Nay; but ye have cursed them, and have hated them, and have not sought to recover them. But behold, I will return all these things upon your own heads; for I the Lord have not forgotten my people.
6 Thou fool, that shall say: A Bible, we have got a Bible, and we need no more Bible. Have ye obtained a Bible save it were by the Jews?
7 Know ye not that there are more nations than one? Know ye not that I, the Lord your God, have created all men, and that I remember those who are upon the isles of the sea; and that I rule in the heavens above and in the earth beneath; and I bring forth my word unto the children of men, yea, even upon all the nations of the earth?
8 Wherefore murmur ye, because that ye shall receive more of my word? Know ye not that the testimony of two nations is a witness unto you that I am God, that I remember one nation like unto another? Wherefore, I speak the same words unto one nation like unto another. And when the two nations shall run together the testimony of the two nations shall run together also.
9 And I do this that I may prove unto many that I am the same yesterday, today, and forever; and that I speak forth my words according to mine own pleasure. And because that I have spoken one word ye need not suppose that I cannot speak another; for my work is not yet finished; neither shall it be until the end of man, neither from that time henceforth and forever.
10 Wherefore, because that ye have a Bible ye need not suppose that it contains all my words; neither need ye suppose that I have not caused more to be written.
11 For I command all men, both in the east and in the west, and in the north, and in the south, and in the islands of the sea, that they shall write the words which I speak unto them; for out of the books which shall be written I will judge the world, every man according to their works, according to that which is written.
1 Nephi 13:38 And it came to pass that I beheld the remnant of the seed of my brethren, and also the book of the Lamb of God, which had proceeded forth from the mouth of the Jew, that it came forth from the Gentiles unto the remnant of the seed of my brethren.
39 And after it had come forth unto them I beheld other books, which came forth by the power of the Lamb, from the Gentiles unto them, unto the convincing of the Gentiles and the remnant of the seed of my brethren, and also the Jews who were scattered upon all the face of the earth, that the records of the prophets and of the twelve apostles of the Lamb are true.
40 And the angel spake unto me, saying: These last records, which thou hast seen among the Gentiles, shall establish the truth of the first, which are of the twelve apostles of the Lamb, and shall make known the plain and precious things which have been taken away from them; and shall make known to all kindreds, tongues, and people, that the Lamb of God is the Son of the Eternal Father, and the Savior of the world; and that all men must come unto him, or they cannot be saved.
41 And they must come according to the words which shall be established by the mouth of the Lamb; and the words of the Lamb shall be made known in the records of thy seed, as well as in the records of the twelve apostles of the Lamb; wherefore they both shall be established in one; for there is one God and one Shepherd over all the earth.
