The Book of Mormon is “Another Testament of Jesus Christ.” It is a dynamic and vibrant witness for the mission of the Savior and the efficacy of His atoning sacrifice. It is a roadmap of security and covenant honor for the latter days. As Moroni closes this sacred record, the most correct of any book, he issues the clarion call to come unto Christ, which process is the very objective and mission of The Church of Jesus Christ of Later-day Saints, the kingdom of God here upon the earth. The Lord issues the same call: “Come unto me” (see Matthew 11:28; John 7:37; 2 Nephi 26:25; Alma 5:34–35; 3 Nephi 18:25; Moroni 7:34; D&C 45:5). The Lord truly wants all to come unto him: “He inviteth them all to come unto him and partake of his goodness; and he denieth none that come unto him, black and white, bond and free, male and female; and he remembereth the heathen; and all are alike unto God, both Jew and Gentile” (2 Nephi 26:33). When we come unto Christ with full purpose of heart, even with a broken heart and contrite spirit, and deny ourselves of all ungodliness (anything that is contrary to God and His commandments), He will, by the grace of God, make us perfect in and through Him, who is mighty to save, after all we can do (see 2 Nephi 25:23). We will be just men and women made perfect (see D&C 76:69). It is by the grace of God that we can be made perfect in Christ. All blessings come by the grace of God—for that is the only way we can become sanctified, made clean and pure, worthy to be admitted into the rest of God, “which rest is the fullness of his glory” (D&C 84:24).
Elder Russell M. Nelson confirms this transcendent doctrine: “Moroni taught how to gain this glorious objective. His instruction stands in any age as an antidote for depression and a prescription for joy. I echo his plea: ‘Come unto Christ, and be perfected in him, and deny yourselves of all ungodliness; … love God with all your might, mind and strength, then … ye may be perfect in Christ … holy, [and] without spot.’ (Moroni 10:32–33)” (Perfection Pending, and Other Favorite Discourses [Salt Lake City: Deseret Book, 1998], 9).
