“Even as Jesus himself is the light of the world, so he expects his saints to set perfect examples of righteousness so that they too shall shine forth as lights to their fellow men. ‘Behold I am the light; I have set an example for you,’ he says, and then commands: ‘Hold up your light that it may shine unto the world. Behold I am the light which ye shall hold up—that which ye have seen me do’ (3 Nephi 18:16, 24)” (Bruce R. McConkie, Doctrinal New Testament Commentary, 3 vols. [Salt Lake City: Bookcraft, 1965–1973], 1:218).
