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 Thomas S. Monson's talk, "The Prophet Joseph Smith: Teacher by Example" from the October 2005 general conference:
In the 135th section of the Doctrine and Covenants we read the words of John Taylor concerning the Prophet Joseph: “Joseph Smith, the Prophet and Seer of the Lord, has done more, save Jesus only, for the salvation of men in this world, than any other man that ever lived in it.”
I love the words of President Brigham Young, who said, “I feel like shouting Hallelujah, all the time, when I think that I ever knew Joseph Smith, the Prophet whom the Lord raised up and ordained, and to whom He gave keys and power to build up the kingdom of God on earth.”
