Moroni completes the two phases of the Atonement. The first was overcoming the temporal death. The second comes after the judgment and the assignment to the eternal rewards. It is interesting that Moroni does not similarly qualify this step as overcoming the spiritual death, even though that is the definition that is typically paralleled in the didactive sections of the other prophets. Again, Moroni is not teaching and clarifying principles. He is using them as evidence for the goodness of God.
