What is said of the people of Ammon is what can be said of all true converts: they were known for their zeal, and “they were perfectly honest and … firm in the faith of Christ, even unto the end”; that is, they were solidly committed to the cause of Christ. There was no problem of inactivity among them (compare commentary at Alma 23:1–13). On the meritorious attribute of firmness, see commentary at Jacob 3:1–2.
