In life, there are always things for us to do. When we die, we'll just have to let the many unfinished things go. But it would be nice to know that we have done all we need to have done when we depart from this world, so that we can leave in peace. This is possible if we always do what God wants us to do, not what we want to do. When the Lord calls, we know that we've accomplished everything we need to have done for him.
