Ch. 53-54 Book of Mormon Stories and Discussion. After Mormon died, Moroni finished the records his father had given him. In this episode we learn how Moroni wrote many important things so that others could come to know Jesus Christ. Also, we learn about the promise that Moroni wrote. He told people to read the records, then ask Heavenly Father if they are true. If they ask sincerely, with faith in Christ, the Holy Ghost would help them know that the records are true.
