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 Dallin H. Oaks's talk, "The Light and Life of the World" from the October 1987 general conference:
We love the Lord Jesus Christ. He is the Messiah, our Savior and our Redeemer. His is the only name by which we can be saved (see Mosiah 3:17, Mosiah 5:8; D&C 18:23). We seek to serve him. We belong to his church, The Church of Jesus Christ of Latter-day Saints. Our missionaries and members testify of Jesus Christ in many nations of the world. As the prophet Nephi wrote in the Book of Mormon, “We talk of Christ, we rejoice in Christ, we preach of Christ, we prophesy of Christ, and we write according to our prophecies, that our children may know to what source they may look for a remission of their sins” (2 Ne. 25:26).
As we state in our first article of faith, “We believe in God, the Eternal Father, and in His Son, Jesus Christ, and in the Holy Ghost.” [A of F 1:1] God the Father, the great Elohim, the Almighty God, is the Father of our spirits, the framer of heaven and earth, and the author of the plan of our salvation (see Moses 1:31–33; Moses 2:1–2; D&C 20:17–21). Jesus Christ is his Only Begotten Son, Jehovah, the Holy One and God of Israel, the Messiah, “the God of the whole earth” (3 Ne. 11:14).
Watch this powerful testimony of Christ given by modern-day apostles.
