I’ve already commented on the main significance of this miracle. Wine is a symbol of joy, especially of joy in the coming Messianic kingdom. The six stone waterpots that were for the Jewish custom of purification point to the old rituals of Judaism that could not completely satisfy. Jesus fulfilled those ceremonial rituals with the abundant joy of salvation and new life in Him. He is the Son of God who brings the transforming joy of salvation to all that believe. Leon Morris states (p. 176): “This particular miracle signifies that there is a transforming power associated with Jesus. He changes the water of Judaism into the wine of Christianity, the water of Christlessness into the wine of the richness and the fullness of eternal life in Christ, the water of the law into the wine of the gospel.”
