3 Nephi 17-19
The Book of Mormon confirms the teachings of the Old Testament. It confirms the teachings of the New Testament. It restores “many plain and precious things” (1 Ne. 13:28) lost or taken from them (see also 1 Ne. 13:20–42; 1 Ne. 14:23). It is in truth another testament of Jesus Christ.
This year we celebrate the 175th anniversary of the organization of the Church and the 200th anniversary of the birth of the Prophet Joseph Smith. In the Church, much will be written and said to honor him.
As usual, there will be much said and written to discredit him. There always were, are now, and ever will be those who stir into 200-year-old dust, hoping to find something Joseph is alleged to have said or done in order to demean him.
The revelations tell us of “those that shall lift up the heel against mine anointed, saith the Lord, and cry they have sinned when they have not sinned before me, saith the Lord, but have done that which was meet in mine eyes, and which I commanded them” (D&C 121:16). They face very stern penalties, indeed.
We do not have to defend the Prophet Joseph Smith. The Book of Mormon: Another Testament of Jesus Christ will defend him for us. Those who reject Joseph Smith as a prophet and revelator are left to find some other explanation for the Book of Mormon.
And for the second powerful defense: the Doctrine and Covenants, and a third: the Pearl of Great Price. Published in combination, these scriptures form an unshakable testament that Jesus is the Christ and a witness that Joseph Smith is a prophet.
And I join the millions of others who have that testimony, and bear it to you in the name of Jesus Christ, amen. (“The Book of Mormon:Another Testament of Jesus Christ—Plain and Precious Things,” Ensign, May 2005.)
