The Book of Mormon plays an important part in the conversion of many people. Moroni specifically mentioned the benefit that would come to the Lamanites in the latter days as a result of the Book of Mormon. One of the earliest missionary calls in this dispensation was to Oliver Cowdery and his companions to teach the Lamanites living on the western frontier (Missouri) of early America (see D&C 28:8–10). Today the Church takes the gospel message to everyone, including the descendants of Lehi, who are scattered throughout the world.
