The Lord revealed to the Prophet Joseph Smith that he “should translate … the engravings of Nephi, and send forth … this work [which contains] all those parts of my gospel which my holy prophets … desired in their prayers should come forth unto this people. And I said unto them, that it should be granted unto them according to their faith in their prayers” (D&C 10:45–47; see also D&C 3:16–20).
How has the Book of Mormon fulfilled the faith and prayers of its writers? How does knowing the Lord will fulfill His promises increase your faith in what you pray for?
