One of the most distinguishing features of The Church of Jesus Christ of Latter-days Saints is our acceptance of the Book of Mormon as a companion volume of scripture alongside the Bible. For millions of Latter-day Saints around the world, we revere the Book of Mormon as the word of God, a sacred scriptural text recorded by ancient prophets in the Western Hemisphere and preserved for our day as a second powerful witness to the Bible that Jesus is the Christ.
How the Book of Mormon came into existence is an incredible story: an uneducated farm boy in upstate New York, visitations from heavenly messengers, and plates of gold with engravings in an ancient language.
Reason #1: An undeniable witness from the Holy Ghost that the Book of Mormon is true.
Repeatedly in the New Testament, Jesus taught His disciples that they could know and understand truth through the witness of the Holy Ghost.
