Mormon’s custom is to note not only the passage of years, but also specific times when there was peace. What is common to his writing about years of peace is that he says virtually nothing about them. Mormon teaches that keeping the commandments led to prosperity, but he doesn’t see that prosperity is of the same instructional value as the events which lead the people away from such joy and prosperity. Thus, in verse 33, we see that pride is again entering “into the hearts of the people.” We know that nothing good will come of it.
