Yes this children's Optometrist made a 'ground-breaking' contribution to his profession, drawing a link between children's behaviour and eye sight problems. He even got two mentions in our local paper. All right, what I mean to say is not all of us are going to be famous or well-known in this world or make 'ground-breaking' contributions to our areas of expertise, but we can all be the best that we can be. By this, I don't mean in comparing ourselves to others but just in being the best that we can be ourselves and using our talents wisely, how many or how few.
Jesus in changing the water into wine (John 2 v 7-10) made sure that the changed wine wasn't just any old wine but the very best, top quality wine. Let's be the very best in whatever we do Optometry or writing and make sure, if we can, that in doing what we do, we try to make the lives of others around us somewhat better for our having been here on the earth.
