I delivered something similar to this to my ward a couple of weeks ago.
Some years ago I took [my son] with me while working in upstate New York. We visited Seneca Falls, Fayette, and Palmyra. I was delighted that some of the history nerdiness that saturates our household had permeated him as demonstrated by his cheerful responses to the missionaries and his piercing questions. I keep my favorite memory of those days from the Grandin printing office. After walking through the exhibits demonstrating the publication methods of the Book of Mormon, the missionaries directed us to a hanging copy of “Moroni’s Promise.” One sister earnestly explained it to [my son] and asked if he had ever followed its exhortation. “No,” he responded, and the missionary’s eyes flashed with the opportunity. “I don’t need to.” And I leaned over and whispered that I didn’t either. I was grateful at that moment that my son had learned that there is more than one story associated with that scripture.
