Mormon was called of God to serve as chief administrator in finalizing the ultimate structure and content of the Book of Mormon. With the help of his son, Moroni, he completed his assigned mission—“even a marvellous work and a wonder” as foretold by prophecy. Because of their organizational skills, and through the sustaining power of the Spirit of the Lord, Mormon and Moroni were able to bring forth for the latter days God’s plan of salvation and exaltation, which is a book of prayer, a book of fasting, a book of faith, a book of learning, a book of glory, a book of order, a book of God —even “Another Testament of Jesus Christ.”
Mormon’s compilation included the contents of the smaller plates of Nephi in unabridged format.
Mormon’s character is confirmed in the scriptures. Ammaron, the archivist of the sacred records, came to him when Mormon was ten years old and said, “I perceive that thou art a sober child and quick to observe”. Ammaron promised Mormon that he would be commissioned to take over the task of record-keeper when he attained the age of around twenty-four. The following year, when violent conflict was erupting between the Nephites and Lamanites, Mormon was taken by his father, also Mormon, to Zarahemla. It was there, several years later, that the youth received a heavenly manifestation. “And I, being fifteen years of age and being somewhat of a sober mind, therefore I was visited of the Lord, and tasted and knew of the goodness of Jesus”. Shortly thereafter, in his sixteenth year, Mormon, being large in stature, was appointed commander of the armies of the Nephites. The remainder of his years were spent balancing the demands of military service with the commission to guard and preserve the sacred records and complete his assignment as compiler and abridger. He loved his people—despite their wickedness—and this allowed him to rise to their defense.
Behold, I had led them, notwithstanding their wickedness I had led them many times to battle, and had loved them, according to the love of God which was in me, with all my heart; and my soul had been poured out in prayer unto my God all the day long for them; nevertheless, it was without faith, because of the hardness of their hearts.
Mormon’s love for the Lord, and his understanding of the significance of the manner in which the sacred record would bless future lives, propelled him always forward.
And he hath brought to pass the redemption of the world, whereby he that is found guiltless before him at the judgment day hath it given unto him to dwell in the presence of God in his kingdom, to sing ceaseless praises with the choirs above, unto the Father, and unto the Son, and unto the Holy Ghost, which are one God, in a state of happiness which hath no end.
Therefore repent, and be baptized in the name of Jesus, and lay hold upon the gospel of Christ, which shall be set before you, not only in this record but also in the record which shall come unto the Gentiles from the Jews, which record shall come from the Gentiles unto you.
For behold, this the Book of Mormon] is written for the intent that ye may believe that [the Bible]; and if ye believe that ye will believe this also; and if ye believe this ye will know concerning your fathers, and also the marvelous works which were wrought by the power of God among them.
History: Mormon was born around AD 310. He commanded the Nephite forces from the time he was sixteen until the final battle at [Cumorah in which he witnessed the destruction of nearly a half million of his people. Nevertheless, Mormon himself kept his eye single to the glory of God and remained faithful to the end, eventually turning over the sacred commission as record keeper to his son Moroni. Both prophets were administered to by the tarrying disciples of Christ until even these were withdrawn by the Lord because of the universal wickedness of the people. Mormon was finally killed by the warring Lamanites around AD 385 , leaving Moroni alone to finish the work of the Lord.
