The miracle indeed of our Lord Jesus Christ, whereby He made the water into wine, is not marvellous to those who know that it was God's doing. For He who made wine on that day at the marriage feast, in those six water-pots, which He commanded to be filled with water, the self-same does this every year in vines. For even as that which the servants put into the water-pots was turned into wine by the doing of the Lord, so in like manner also is what the clouds pour forth changed into wine by the doing of the same Lord. But we do not wonder at the latter, because it happens every year: it has lost its marvellousness by its constant recurrence. And yet it suggests a greater consideration than that which was done in the water-pots. For who is there that considers the works of God, whereby this whole world is governed and regulated, who is not amazed and overwhelmed with miracles? If he considers the vigorous power of a single grain of any seed whatever, it is a mighty thing, it inspires him with awe. But since men, intent on a different matter, have lost the consideration of the works of God, by which they should daily praise Him as the Creator, God has, as it were, reserved to Himself the doing of certain extraordinary actions, that, by striking them with wonder, He might rouse men as from sleep to worship Him.
Augustine, Tractate 8 on the Gospel of John
