May Christ lift thee up also has a meaning beyond mortality. Through the atonement of Jesus Christ, righteous men and women will be “lifted up” to meet the Savior at his glorious second coming (see D&C 45:45; D&C 88:96-97) and are “lifted up” by Jesus to an inheritance of exaltation and eternal life (see 3 Nephi 27:13-21; Mosiah 23:22; Alma 13:29; D&C 5:35; D&C 9:14; D&C 52:43-44).
“May Christ Lift Thee Up”
There appears to be a double meaning in this phrase. Mormon is worried that his descriptions of the horrible wickedness and bloodshed among the Nephites and the Laminates will cause Moroni to become so despondent and discouraged that he is “weighed down unto death.” Mormon’s hope that Christ will lift his son up refers to a lifting of Moroni’s emotions and spirit. Amidst adversity arid affliction Christ can and does lift our spirits and gives its hope and strength to carry on (see 1 Peter 5:7; Matthew 11:28-30).
