But behold, there shall be many -- at that day when I shall proceed to do a marvelous work among them, that I may remember my covenants which I have made unto the children of men, that I may set my hand again the second time to recover my people, which are of the house of Israel;If the Book of Mormon were a mere forgery, there is no way that Joseph Smith or his associates could have actually known that the book would spread to the ends of earth, that even 175 years later in our day it would be translated into many dozens of languages and serve as the Church's primary missionary tool to act as a standard for gathering people into the Church. Could he also have known that the Book of Mormon would indeed be so strongly opposed by "the Gentiles"? Even to this very day, the primary response to the Book of Mormon of many in the nominally Christian world of "the Gentiles" is to repeat the words prophesied by Nephi, calling the Book of Mormon a "Bible" (we never call it that) and chanting the mantra that LDS missionaries are so familiar with: "We already have a Bible and there cannot be any more Bible."
 And also, that I may remember the promises which I have made unto thee, Nephi, and also unto thy father, that I would remember your seed; and that the words of your seed should proceed forth out of my mouth unto your seed; and my words shall hiss forth unto the ends of the earth, for a standard unto my people, which are of the house of Israel;
 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.
Sure, you can dismiss this as some kind of self-fulfilling prophecy, but 2 Nephi 29 is far more interesting than that.
For those who are tempted to dismiss the Book of Mormon out of hand because you believe the man-made argument that God has not spoken more, consider the further words of Nephi:
 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?Almost by reflex now, Rev. 22:18,19 will be cited, warning against tinkering with the text ("adding or subtracting"). John is absolutely correct: no mere man has authority to add or subtract from the word of God. In fact, this is an ancient principle that Moses taught in Deuteronomy 4:2:
 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?
 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.
 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.
 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.
Ye shall not add unto the word which I command you, neither shall ye diminish ought from it....Here are the related word of John in Rev. 22:18,19:
For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:In those verses, John, who is in exile on the Isle of Patmos, is obviously referring to the text before him -- the Book of Revelation and its prophecies, its descriptions of plagues, its discussion of the holy city, etc. -- and urges no one to change what he has written. The Bible as a collection of canonized books did not exist when he wrote those lines. In fact, several non-LDS authorities believe that Revelation was not the last book of the Bible to be written, but may have preceded other writings of John himself by a couple of years. Nevertheless, what John wrote is true: no man should change what God has spoken. Don't tinker with the text! However, God has the authority to speak what and when He wants. God spoke to other prophets after Moses (the injunction against men adding to the word in Deut. 4:2 not being applicable to the case of God adding to His words), and many of their divinely commissioned writings have been preserved in the Bible.
And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.
Among the many chosen prophets to whom God spoke anciently, there were some in the New World who were descendants from the House of Israel and who knew of the long-prophesied ministry of the Messiah that would occur in Israel. The Book of Mormon is a record written by such prophets in the New World, covering (with one more ancient exception) a time span of 600 B.C. to 400 A.D. This book, like the Bible, contains a record of God's dealings with a part of the House of Israel. It contains prophecies of Christ and also reveals how Christ, after his resurrection and ascension into heaven, later ministered to those who had waited for him in the New World.
How grateful we should be that God has provided another testament to confirm the reality of Jesus Christ and add more hope and knowledge in these dark and troubled days. Why should we murmur because of His grace in giving us more help, more light and more knowledge? Praise be to God for the divine truths revealed in the Bible and the Book of Mormon, companion volumes of scripture that the world desperately needs today to help all men come to Christ and find the joy that He alone offers.
