Here is another explicit contrast. Mormon invokes the ghost of Ammonihah by citing what the believers were fortifying themselves against. The hardening against the word, the unbelieving, and particularly the destruction, are direct references to the story of Ammonihah. This is contrasted with the true believers, who "enter into the rest of the Lord…" which was another recurrent theme of Alma's discourse in Ammonihah. We should see this paragraph as clearly linked to the events of the story as Mormon told them. We are in the midst of Mormon's extraction of the moral of the story he has just included.
