Things on earth don't have much value. They will all pass away. It's the value we place on it that gives it meaning. For instance, my wedding ring. It's just a piece of metal with hardened rocks, yet i'd be devastated to lose it. The ring represents the covenant I have made with my husband. Our relationship means the world to me, losing something symbolic of our marriage is the devastating part, not losing a piece of metal with hardened rocks ;)
