Mormon’s conclusion to this section pulls together the threads of the argument. How may Mormon’s audience know that what he has said is true? “God will show unto you … that they are true.”
Then, Mormon returns to the important arguments. The God of their past is the God of their present, the God of their future. The faith that supported the ministration of angels and of miracles might be dormant, but it is not removed. With true faith, all of those hallmarks of the great faith of the past may return to our present.
Finally, the greatest miracle is to be saved, and that requires that “they shall have faith in his name.” Faith in Christ is required. Faith in Christ is possible.
This ends Mormon’s section explaining faith. He moves to the principle of hope in the next verses.
