Christ spoke of the inability of the wicked to “understand with their heart” (Matthew 13:15), while the righteous “understood in their hearts” things too marvelous to utter (3 Nephi 19:33-34). Describing the spirit of revelation for Joseph Smith, the Lord said, “I will tell you in your mind and in your heart, by the Holy Ghost, which shall come upon you and which shall dwell in your heart” (D&C 8:2). Because of their wickedness, such understanding was lost to Nephi’s rebellious brothers.
