Mormon’s Calling and Election Is Made Sure
Mormon 2:19
19 And 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.
Elder Bruce R. McConkie wrote:
“Those members of the Church who devote themselves wholly to righteousness, living by every word that proceedeth forth from the mouth of God, make their calling and election sure. That is, they receive the more sure word of prophecy, which means that the Lord seals their exaltation upon them while they are yet in this life. . . . ‘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).”
