Moroni’s love for, and understanding of, the principles of faith, hope, and charity, is demonstrated in the long explanation his father gave in the sermon that Moroni included as Moroni 7. These verses restate that understanding without any further explanation. The emphasis here is to point to the end of our earthly existence, to being saved in the kingdom of God. Since Moroni is clearly writing to the future, it is both the temporal and spiritual future that hold his interest.
Moroni exhorts his future readers to have faith, and to have hope in the correct goal. That is the type of faith which changes us, and can exalt us.
