War-What's it Good For?

Why do we have these war chapters at the end of Alma? Bryan says it's so that boys will read the scriptures. Someone in our ward mentioned it was a good source for learning primitive war strategy. Although those are both good reasons for recording this type of history, I am inclined to think that there must be something a little deeper that we are to learn. Something along the lines of an example to us of how our belief in the Savior can impact our lives. How our faith and obedience can directly influence the happiness that we experience. We won't be exempt from trial and hardship, but can avoid some things and we will be better prepared to handle the inevitable. It's truly a comfort to know that the Lord is watching over me and that I can call on His name whenever I need a little help from someone who loves me.
