Ezra Taft Benson:
"The Book of Mormon brings men to Christ through two basic means. First, it tells in a plain manner of Christ and his gospel. It testifies of his divinity and of the necessity for a Redeemer and the need of our putting trust in him. It bears witness of the Fall and the Atonement and the first principles of the gospel, including our need of a broken heart and a contrite spirit and a spiritual rebirth. It proclaims we must endure to the end in righteousness and live the moral life of a Saint.
Second, the Book of Mormon exposes the enemies of Christ. It confounds false doctrines and lays down contention. (See 2 Ne. 3:12 below.) It fortifies the humble followers of Christ against the evil designs, strategies, and doctrines of the devil in our day. The type of apostates in the Book of Mormon are similar to the type we have today. God, with his infinite foreknowledge, so molded the Book of Mormon that we might see the error and know how to combat false educational, political, religious, and philosophical concepts of our time.
Now God expects us to use the Book of Mormon in several ways. We are to read it ourselves—carefully, prayerfully—and ponder as we read, as to whether this book is the work of God or of an unlearned youth. And then when we are finished reading the things in the book, Moroni exhorts us to put them to the test in these words:“And when ye shall receive these things, I would exhort you that ye would ask God, the Eternal Father, in the name of Christ, if these things are not true; and if ye shall ask with a sincere heart, with real intent, having faith in Christ, he will manifest the truth of it unto you, by the power of the Holy Ghost.” (Moro. 10:4.) I have done as Moroni exhorts, and I can testify to you that this book is from God and so is verily true." Ezra Taft Benson, “The Book of Mormon Is the Word of God,” Ensign, May 1975, 63
2 Nephi 3:12
12 Wherefore, the fruit of thy loins shall write; and the fruit of the loins of Judah shall write; and that which shall be written by the fruit of thy loins, and also that which shall be written by the fruit of the loins of Judah, shall grow together, unto the confounding of false doctrines and laying down of contentions, and establishing peace among the fruit of thy loins, and bringing them to the knowledge of their fathers in the latter days, and also to the knowledge of my covenants, saith the Lord.
