The Lord said to “teach the principles of my gospel, which are in the Bible and the Book of Mormon, in the which is the fulness of the gospel” (Doctrine & Covenants Section 42:12)
The Bible and Book of Mormon complement and enrich each other (see Ezekiel 37:16–17; 1 Nephi 13:40; Mormon 7:8–9). Both volumes of scripture are compilations of teachings recorded by ancient prophets. The Bible tells of God’s interactions with people in the Eastern Hemisphere for thousands of years. The Book of Mormon tells of God’s interactions with people in the ancient Americas for more than a thousand years.
The central purpose of the Book of Mormon is to testify of Jesus Christ. It affirms the reality of His life, mission, resurrection, and power. It teaches true doctrine about Christ and His Atonement.
As people read and pray about the Book of Mormon, they will come to know the Savior better and experience His love. They will grow in their testimony of Him. They will know how to come unto Him and be saved.
