From the Book of Mormon come other precious promises, including promises of peace, freedom, and blessings if we “will but serve the God of the land, who is Jesus Christ” (Ether 2:12).
From its pages comes the promise of “never-ending happiness” to “those that keep the commandments of God. For behold, they are blessed in all things, both temporal and spiritual” (Mosiah 2:41).
From its pages comes the promise of “incomprehensible joy” to those who become “instrument[s] in the hands of God” in rescuing His precious sons and daughters (Alma 28:8; 29:9).
From its pages comes the promise that scattered Israel will be gathered—a work in which we are engaged through our great worldwide missionary efforts (see 3 Nephi 16; 21–22).
From its pages comes the promise that as we pray unto the Father in the sacred name of Jesus Christ, our families will be blessed (see 3 Nephi 18:21).
From a study of its pages comes the fulfillment of the prophetic promise that “there will come into your lives and into your homes an added measure of the Spirit of the Lord, a strengthened resolution to walk in obedience to His commandments, and a stronger testimony of the living reality of the Son of God.”1
And from the pages of the Book of Mormon comes Moroni’s promise that through prayer, real intent, and faith in Christ, we may know the truth of these promises “by the power of the Holy Ghost” (see Moroni 10:4–5).
