The Book of Mormon is a sacred text of the Latter-day Saint movement, published in 1830 by Joseph Smith. It is considered by adherents to be a record of ancient American civilizations and their dealings with God. The book is divided into smaller books, each detailing the history, prophecies, and teachings of various prophets. The narrative primarily follows the journey of a family, the Nephites, who fled Jerusalem around 600 B.C. and settled in the Americas. It also includes the account of the Lamanites, their descendants, and the teachings of Jesus Christ after His resurrection. The book emphasizes faith, repentance, and the importance of following God's commandments.
