The Divine Mission of Jesus Christ: Light of the World
As we come to understand that Jesus Christ is the Light of the World, we will increase our faith in Him and become a light to others. Christ testified of His role as “the true light that lighteth every man [and woman] that cometh into the world” (D&C 93:2) and asked that we “hold up [His] light that it may shine unto the world” (3 Nephi 18:24).
Elder Quentin L. Cook of the Quorum of the Twelve Apostles said of our being a light to the world: “We need to protect our families and be at the forefront together with all people of goodwill in doing everything we can to preserve light, hope, and morality in our communities.”
Supplement: Read the following excerpt from Elder Dallin H. Oaks's talk "The Light and Life of the World," from the October 1987 general conference.
Jesus Christ is the light of the world because he is the source of the light which “proceedeth forth from the presence of God to fill the immensity of space” (D&C 88:12). His light is “the true light that lighteth every man that cometh into the world” (D&C 93:2; see also D&C 84:46). The scriptures call this universal light “the light of truth” (D&C 88:6), “the light of Christ” (D&C 88:7; Moro. 7:18), and the “Spirit of Christ” (Moro. 7:16). This is the light that quickens our understanding (see D&C 88:11). It is “the light by which [we] may judge” (Moro. 7:18). It “is given to every man, that he may know good from evil” (Moro. 7:16).
Jesus Christ is also the light of the world because his example and his teachings illuminate the path we should walk to return to the presence of our Father in Heaven.
