In his grand vision, Nephi witnesses the birth of the Savior in the meridian of time by means of which the Redeemer, by choice, takes upon Himself mortality, an event referred to by the guiding angel as the “condescension of God” (1 Nephi 11:16, 26). The following passage by gospel scholar Kent P. Jackson may shed additional light on this doctrine:
The condescension of God includes the condescension of Jehovah, Christ, the God of the world, who came down from his divine station to become flesh, to minister in mortality, and to suffer and die for the sins of the world. [He then quotes Mosiah 3:5, 7–9.] …
Elder Bruce R. McConkie wrote: “The condescension of God (meaning the Son) consists in the fact that though he himself is the Lord Omnipotent, the very Being who created the earth and all things in it, yet being born of mortal woman, he submitted to all the trials of mortality, suffering ‘temptations, and pain of body, hunger, thirst, and fatigue, even more than man can suffer, except it be unto death’ (Mosiah 3:5–8), finally being put to death in a most ignominious manner.” (Kent P. Jackson, ed., Studies in Scripture, Vol. 7: 1 Nephi to Alma 29 [Salt Lake City: Deseret Book, 1987], 41)
