Something that struck me the other day while I was reading the Book of Mormon was something that was in Alma 53:5. At this point in the Book of Mormon, the Nephites (good guys) had captured a bunch of the Lamanites (bad guys). Instead of just guarding them or putting them in jails, they decided to put them to work. They began to make them build up their fortresses and fortifying them. Something that I found interesting in this verse is where it says, "...it was easy to guard them while at their labor..."
I always try to compare the Lamanites as sin and the Nephites as ourselves. If we are constantly on our guard and doing the things that God has commanded us; we can always be on alert. It is when we are busy doing righteous things that we can receive the most protection.
One more example. While I was serving my mission in the Philippines, I came across some pretty gnarly bugs, my favorite being the banana spider. These spiders can grow to be as large as my hand!
