Alma 62

What do we learn from all of this death and destruction and warfare?  

40 And there had been murders, and contentions, and dissensions, and all manner of iniquity among the people of Nephi; nevertheless for the righteous’ sake, yea, because of the prayers of the righteous, they were spared.

We learn that the prayer of a righteous man availeth much in heaven.

  41 But behold, because of the exceedingly great length of the war between the Nephites and the Lamanites many had become hardened, because of the exceedingly great length of the war; and many were softened because of their afflictions, insomuch that they did humble themselves before God, even in the depth of humility.

We learn to be humble, and to let our afflictions humble into the depths of humility rather than to become hardened because of them.

48 And the people of Nephi began to prosper again in the land, and began to multiply and to wax exceedingly strong again in the land. And they began to grow exceedingly rich.
49 But notwithstanding their riches, or their strength, or their prosperity, they were not lifted up in the pride of their eyes; neither were they slow to remember the Lord their God; but they did humble themselves exceedingly before him.
50 Yea, they did remember how great things the Lord had done for them, that he had delivered them from death, and from bonds, and from prisons, and from all manner of afflictions, and he had delivered them out of the hands of their enemies.
51 And they did pray unto the Lord their God continually, insomuch that the Lord did bless them, according to his word, so that they did wax strong and prosper in the land.

And we learn, very importantly, maybe even more important than being humble in our afflictions, we learn to be humble in our riches and prosperity.

We learn that we must be humble and grateful, for all the prosperity as well as for all the afflictions that we must suffer.
