At that time, then, Jesus made of water wine, and both then and now He ceases not to change our weak and unstable wills. For there are, yes, there are men who in nothing differ from water, so cold, and weak, and unsettled. But let us bring those of such disposition to the Lord, that He may change their will to the quality of wine, so that they be no longer washy, but have body, and be the cause of gladness in themselves and others.
John Chrysostom, Homily 22 on the Gospel of John
