These comments follow immediately upon Moroni’s understanding his personal weakness in writing would not be a hindrance. The reason is that faith can overcome his weakness. Thus, in verse 29 he had said, “For I know that thou workest unto the children of men according to their faith.” Having declared that God works according to faith, Moroni provides examples of great things that had been done through faith. If the brother of Jared might remove a mountain, God could find a way to make the Book of Mormon a strength rather than an example of weakness in writing.
Verse 28 of this chapter introduced the Pauline formula of faith, hope, and charity. Moroni has taken that trilogy and expanded upon its principles.
These two verses conclude his explication of the requirement of faith. For Moroni, faith is a force that marshals action. Few will ever have the power of the disciples, even less will have the power to move a mountain. Nevertheless, in each individual life, faith provides the power to do and to progress. Faith is usually seen in the small miracles, not the large ones. Faith is often a quiet force that commits us to continue to follow the path to God, even though the way becomes difficult at times.
