Manifest His Glory

Another purpose of this miracle, as with all miracles, was to manifest the glory of the God-man.  Just as on the mount of transfiguration, those at the wedding were given just a taste of the glory to be revealed.  The ultimate purpose of the abundant joy and prosperity in the coming kingdom of the Messiah is to bring glory to God. The miracle at Cana established an important precedent in the ministry of Jesus; He was here as Messiah to bring salvation for the glory of God.
