This verse is written in a letter from Moroni to Pahoran. He's talking about how the government is not sending provisions and soldiers to his armies. The government has so much and is not utilizing what they have been blessed with.
As I studied that verse I realized that I can apply that to my situation. I've been given medical help, friends, family, etc to help me through my fight with bipolar. When I fail to use them I'm wasting what the Lord has blessed me with. I shared that with a friend and she pointed out that it applied financially too. I hadn't even thought if that. Recently I started a new treatment that is very expensive, on top of that I may have to start taking a brand new medication that my insurance won't pay for. If things work out that way, it will add up financially really quickly. It's had me very worried. However, as my friend pointed out, the Lord has blessed us with the means to do what it takes to heal me, we need to utilize what we've been given, whatever resource that is. I love that even reading about the wars in Alma I can find little things to boost me.
