Andrew Skinner notes that Mormon suffered greatly because of the wickedness of his people. However, he was buoyed up and received some comforting in the sure knowledge that he would be lifted up at the last day just as the Savior had promised. (3 Nephi 27:14) Said Mormon, “Wo is me because of their wickedness; for my heart has been filled with sorrow because of their wickedness, all my days; nevertheless, I know that I shall be lifted up at the last day” (Mormon 2:19).
Mormon’s knowledge was well founded. He had received the Second Comforter (D&C 88:3-4, 67-68) and possessed the more sure word of prophecy, as did other Nephite prophets including Alma (Mosiah 26:20), Enos (Enos 1:27), and the Twelve on the American continent (3 Nephi 28:3). Modern revelation teaches: “The more sure word of prophecy means a man’s knowing that he is sealed up unto eternal life, by revelation and the spirit of prophecy, through the power of the Holy Priesthood” (D&C 131:5). Such was the anchor to Mormon’s soul in the face of the worst kind of calamity. [Andrew C. Skinner, “The Course of Peace and Apostasy,” in Studies in Scripture: Book of Mormon, Part 2, pp. 227-228]
