The woman said unto him, Sir, you have nothing to draw with, and the well is deep: from where then have you that living water?
All Commentaries on John 4:11 Go To John 4
Cyril of Alexandria
AD 444
If thou knewest the gift of God, and Who It is That saith to thee, Give Me to drink; thou wouldest have asked of Him, and He would have given thee living water. The woman saith unto Him,
Not knowing the Essence of the Only Begotten, surpassing earth and heaven, yea rather being wholly ignorant of the Incarnate Word, the woman was calling Him a Jew. And profitably is He silent to this, that the foundation of His discourse with her may be kept. Yet does He uplift her to a higher conception of Himself, saying that she knows not Who It is Who asked drink, or how great grace Divine gifts have, insomuch that if she had had knowledge of it, she would not have endured to be behindhand, for she would have prevented the Lord in asking. He rouses her then by these things to a very earnest wish to learn. Observe how now too fashioning His discourse skillfully and free from boast, He says that He is God, even though the woman be slow to understand. For inducing her to marvel at the gift of God, He introduces Himself as the Giver of it. For if (says He,) thou knewest the gift of God and Who It is That saith to thee, thou wouldest have asked of Him. But whom would it befit to give the things of God? would it not Him Who is by Nature God?
But He calls the quickening gift of the Spirit living water, whereby alone human nature, albeit well nigh parched to its very roots, rendered now dry and barren of all virtue by the villainies of the devil, runneth back to its pristine beauty of nature, and drinking in the life-giving grace, is adorned with varied forms of good things, and shooting forth into a virtuous habit puts forth most thriving shoots of love towards God. Some such thing as this God says to us by the Prophet Isaiah also, The beast of the field shall honour Me, the dragons and the owls, because I give waters in the wilderness, and rivers in the desert, to give drink to My people, My chosen, whom I have formed for Myself to declare Mine excellencies. And another of the Saints says that the soul of the righteous shall be as a fruitful tree, and shall spring up as grass among the waters, and shall appear as the willow by running water.
We might heap up, besides those already quoted, many other testimonies also from the Divine Scripture, whence it would be very easy to shew, that under the name of water, the Divine Spirit is often named. But it is no time to linger here. Wherefore we will swim to other places, pressing on upon the great and wide sea of Divine meditations.
