In verse 10, Aaron says what many modern readers might be thinking: “I fear that thy joy doth carry thee away unto boasting.” It does appear to be a version of “aren’t we great?” There is a difference between suggesting that such a great success was due to Ammon and his brothers’ actions and declaring that it was the hand of the Lord. Ammon makes it clear that he understands the difference. He says that “I do not boast in my own strength, nor in my own wisdom.” Ammon understands that he and his brothers have been instruments that the Lord used for His own purposes. The conversion of so many was through the Spirit, not through the sons of Mosiah.
This discourse of Mormon reminds his readers that God cares for all, even those who have at one time fallen from their covenants to the house of Israel. When those who had been lost have the opportunity to be touched by the Spirit, they may enter the covenant again, and be exemplary members of the house of Israel.
