sure, you can turn water into wine, but why would you?

 The first miracle Jesus performed was to change water into wine (Jn 2). This miracle saved the reputation of the hosts and probably saved the servants from being punished for not having enough wine on hand. John calls the miracle a 'sign,' but we might wonder is this a sign of Jesus's concern with each person's dignity or is it a sign that He can provide more than we even ask for?
