While the BOM is not what most Christians would consider as "the Word of God", we should be fair in saying that the Gospel is presented in the BOM in several places. However, it would appear that this book was created after reading the Gospel narratives in the Bible. I could quote many other passages but these three should suffice. However, Mormon doctrine goes way beyond Bible truth.
And he also spake concerning the prophets, how great a number had testified of these things, concerning this Messiah, of whom he had spoken, or this Redeemer of the world. (1 Nephi 10:5)
And after he had baptized the Messiah with water, he should behold and bear record that he had baptized the Lamb of God, who should take away the sins of the world. (1 Nephi 10:10)
And I looked and beheld the Redeemer of the world, of whom my father had spoken; and I also beheld the prophet who should prepare the way before him. And the Lamb of God went forth and was baptized of him; and after he was baptized, I beheld the heavens open, and the Holy Ghost come down out of heaven and abide upon him in the form of a dove. (1 Nephi 11:27).
