A pair of missionaries in Santiago, Chile, wrote to their president about a woman they were teaching: “She started reading the Book of Mormon, and she got to the part where Nephi killed Laban. She didn’t understand how God could command someone to kill another. It bothered her, and she went to bed with that doubt. During the night a bolt of lightning woke her up, and she immediately thought of David and Goliath. She thought that if God could command David to kill Goliath, then why not Nephi? Then, she said, a feeling of peace and tranquility came over her.”
