Today being Thursday, I prayed the Luminous Mysteries of the Holy Rosary. I love the second mystery, the Wedding at Cana. The wine ran out. The mother of Jesus told the servers to do whatever he tells them. It seems clear that Mary already knew the greatness of her Son. Jesus told the servers to fill six stone water jars with water, each holding twenty to thirty gallons. So we have a total of 120 to 180 gallons of water. The next thing was that what came out of the jars was wine which the headwaiter, not knowing where it came from, judged to be better than all the wine the guests had tasted so far. Jesus did this as the beginning of his signs and so revealed his glory.
As a miracle, this one is not particularly spectacular, but you don't have to be a scientist to know that water remains water and doesn't become something else without at the least adding something to it. Like all the miracles Jesus performed later on, this one is just as amazing. In my mind he had to be the creator of all things to easily accomplish a feat to us like that.
