Jesus said to the servants, “Fill the jars with water.” And they filled them up to the brim [top]. And he said to them, “Now draw some out and take it to the master of the feast [dinner].” So they took it. When the master of the feast tasted the water… the master of the feast called the bridegroom and said to him, “Everyone serves the good wine first, and when people have drunk freely, then the poor wine. But you have kept the good wine until now.” This, the first of his signs, Jesus did at Cana in Galilee, and manifested his glory. And his disciples believed in him (John 2:7-9,10-11).
Jesus gave much more than a gift at this wedding party. He gave a “sign” with important messages. The disciples had first believed through the witness of John the Baptizer. Their faith had grown through meeting Jesus personally. They began to see how He fit the old prophecies. Now, they saw His first miracle (using power greater than anything in nature) and began to really trust Jesus. They believed in Him.
