There is a universal promise from the Father that we can enjoy the blessing of miracles in our lives. When we ask in faith, “doubting nothing” (verse 21), our prayers will be answered and our requests granted. Does this apply to a select circle of believers? No. The promise is made “even unto the ends of the earth” (verse 21). The gospel of miracles is to be preached “to every creature” (verse 22). And what are these miracles? Principally the wondrous effects of the infinite Atonement in our lives—that we can be transformed into new beings through repentance and the grace and mercy of the Redeemer. Other miracles follow in the lives of the faithful and obedient through the blessings and gifts of the Holy Spirit—including the miracle of testimony within our hearts, for “no man can say that Jesus is the Lord, but by the Holy Ghost” (1 Corinthians 12:3). Moroni soon adds to the record, under inspiration, what is probably the most famous of all the statements from the Book of Mormon: “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. And by the power of the Holy Ghost ye may know the truth of all things” (Moroni 10:4–5). Except for the Atonement itself, what could be a greater miracle than this—to know all things through the Spirit of God?
God is, and was, and always will be a God of miracles. This is the message of Moroni and his father at the end of the Book of Mormon. Their joint declarations encapsulate the essence of the gospel of Jesus Christ and constitute a prophetic summary of the covenant promises and a profoundly moving exhortation for all modern readers to receive the message of truth and prepare for the day of judgment through faith and righteous obedience. All the prophets of God have preached the same universal message. Here is an example from President George Albert Smith:
All who believe in Christ must be baptized. It is the gospel of Jesus Christ that we bear. It is the desire to save the souls of the children of men that burns in our hearts. It is not that we may build ourselves up and become a mighty people financially; it is not that we may have our names glorified in the earth for our accomplishments; but it is that the sons and daughters of God, wherever they may be, may hear this gospel, which is the power of God unto salvation to all those who believe and obey its precepts. And those who believe will follow the pattern given by the Savior when he said to his disciples, “He that believeth and is baptized shall be saved; but he that believeth not shall be damned” (Mark 16:16).
