As Moroni wraps up his contribution to the Book of Mormon, he pulls themes from earlier sections of what he or his father had written. In this case, we find the reintroduction of the faith, hope, charity theme that was prominent in the discourse from Mormon that Moroni includes as Moroni 7. In this context, he visits the theme of faith hope and charity as an outgrowth of his discussion of the need for one to confirm the truthfulness of the Book of Mormon through the Spirit. That process is inherently based upon faith, and it is therefore appropriate to revisit that formulation. The repetition also serves to reinforce the presence of the theme in the earlier chapter.
