What is most remarkable about the sons of Mosiah is not that they were brave enough to teach the gospel to the Lamanites, but that they were successful. Many Nephites had previously tried to convert the Lamanites but had failed miserably (Jacob 7:24). Although the Lamanites of Ammon's day may have been more receptive, the success of the sons of Mosiah is truly amazing. It was not the effect of their natural intellects or superior methods but their ability to call upon the power of heaven and convert through the Holy Spirit.
