But you don't have to be a Christian, or even particularly religious, to serve. You just have to be willing to understand your place and put yourself at the end of the line. Still, my faith has helped me toward a deeper understanding of what service really means. You do what's expected of you, and more. You look after others, and put their welfare ahead of your own. You don't worry about the big purpose of it all- it's beyond your pay grade. But if you do the small things right long enough, you might find yourself coming out the other side having done something important.It's an evolution you follow, a tour on the great Ferris wheel, which doesn't have to burn. It never stops turning until the day you take your last breath. And you hope that by the time you leave this earth it will be a better place than it was when you got here. The causes you've served in your life will have meant something. Someone will have picked up your work, run with a legacy you left behind, and used it to put his or her own stamp on the world.
