Scriptures on The Coming forth of the Book of Mormon:
-The Lord told the Nephites of another sign: the Book of Mormon would come to their descendants (see 3 Nephi 21). In Old Testament times the prophets Isaiah and Ezekiel foresaw the coming of the Book of Mormon (seeIsaiah 29:4–18; Ezekiel 37:16–20)
-God knowing what was to happen on earth, the calamities and lack of faith, gave the world the Book of Mormon (D&C 1:17-23)
-The Book of Mormon proves that the scriptures are true, contains the fullness of the gospel, and was translated by the power of God via Joseph Smith (D&C 20:5-12)
-Process of the Book coming forth see Joseph Smith—History 1:27–64.
-3 Ne. 15: the people of the Book of Mormon were visited by Jesus Christ (in ancient America’s) and it’s of them that he spoke when he said John 10:16
16 And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
(see also D&C 10:59-60).
