Note: As the Church has said, the manual has been prepared as the primary source of lesson material. These supplements, from general conference addresses, are meant only as a complement to your study on this lesson’s topic.
Supplement is from Elder Bruce D. Porter's talk, "Saftey for the Soul" from the October 2009 general conference:
Now, I did not sail with the brother of Jared in crossing an ocean, settling in a new world. I did not hear King Benjamin speak his angelically delivered sermon. I did not proselyte with Alma and Amulek nor witness the fiery death of innocent believers. I was not among the Nephite crowd who touched the wounds of the resurrected Lord, nor did I weep with Mormon and Moroni over the destruction of an entire civilization. But my testimony of this record and the peace it brings to the human heart is as binding and unequivocal as was theirs. Like them, “[I] give [my name] unto the world, to witness unto the world that which [I] have seen.” And like them, “[I] lie not, God bearing witness of it.”
I ask that my testimony of the Book of Mormon and all that it implies, given today under my own oath and office, be recorded by men on earth and angels in heaven. I hope I have a few years left in my “last days,” but whether I do or do not, I want it absolutely clear when I stand before the judgment bar of God that I declared to the world, in the most straightforward language I could summon, that the Book of Mormon is true, that it came forth the way Joseph said it came forth and was given to bring happiness and hope to the faithful in the travail of the latter days.
