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 Ezra Taft Benson's talk, "Jesus Christ: Our Savior and Redeemer" from the October 1983 general conference:
His unique heredity made Him heir to the honored title—The Only Begotten Son of God in the flesh. As the Son of God, He inherited powers and intelligence which no human ever had before or since. He was literally Immanuel, which means “God with us.” (See Matt. 1:23.)
Even though He was God’s Son sent to earth, the divine plan of the Father required that Jesus be subjected to all the difficulties and tribulations of mortality. Thus He became subject to “temptations, . . . hunger, thirst, and fatigue.” (Mosiah 3:7.)
To qualify as the Redeemer of all our Father’s children, Jesus had to be perfectly obedient to all the laws of God. Because He subjected Himself to the will of the Father, He grew “from grace to grace, until he received a fulness” of the Father’s power. Thus He had “all power, both in heaven and on earth.” (D&C 93:13, 17.)
