Their Scornful Reaction Is, In Reality, Guilt Trying to Reassure Itself

Prophets through the ages have always come under attack by the finger of scorn. Why? According to the scriptures, it is because “the guilty taketh the truth to be hard, for it cutteth them to the very center” (1 Nephi 16:2), or as President Harold B. Lee observed, “The hit bird flutters!”2 Their scornful reaction is, in reality, guilt trying to reassure itself, just as with Korihor, who finally admitted, “I always knew that there was a God” (Alma 30:52). Korihor was so convincing in his deception that he came to believe his own lie (see Alma 30:53).
