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 President Henry B. Eyring's talk, "An Enduring Testimony of the Mission of the Prophet Joseph" from the October 2003 general conference:
The Prophet Joseph is an example and a teacher of enduring well in faith. I do not worship him, but I thank and love him as the Lord’s prophet of the Restoration. He has helped me pray with the intent to obey. I am better able to feast in the word and the love of God. Because of him I feel the Holy Ghost more often in the moments when I try to build the faith of a person in the Lord’s kingdom. And because of what I know of the Prophet Joseph and the scriptures which were revealed through him, I more often feel the love of God for His children and of His for me when I reach down to lift someone up.
