How do we know that Lamoni was converted and had a change of heart?

Thomas R. Valletta

“His determination not to kill his best friend reveals to our senses the real change that had come into Lamoni’s heart. He was willing to incur his father’s wrath to protect the innocent. Before Ammon’s visit, Lamoni exhibited all those qualities which mark the savage breast, or which fixed a life without God. He was proud and haughty, cruel and overbearing, superstitious and irrational; his word was law. But now he was gentle and considerate, firm in keeping the commandments of God” (Reynolds and Sjodahl, Commentary on the Book of Mormon, 3:284–85).
