John 7:38

(Hom. li. 1) He is speaking of spiritual drink, as His next words shew: He that believeth on Me, as the Scripture hath said, out of his belly shall flow rivers of living water. But where does the Scripture say this? No where. What then? We should read, He that believeth in Me, as saith the Scripture, putting the stop here; and then, out of his belly shall flow rivers of living water: the meaning being, that that was a right kind of belief, which was formed on the evidence of Scripture, not of miracles. Search the Scriptures, He had said before.

(Hom. li. 1) He says, rivers, not river, to show the copious and overflowing power of grace: and living water, i. e. always moving; for when the grace of the Spirit has entered into and settled in the mind, it flows freer than any fountain, and neither fails, nor empties, nor stagnates. The wisdom of Stephen, the tongue of Peter, the strength of Paul, are evidences of this. Nothing hindered them; but, like impetuous torrents, they went on, carrying every thing along with them.

(Hierom. in prolog. Gen.) Or this testimony is taken from the Proverbs, where it is said, Let thy fountains be dispersed abroad, and rivers of waters in the streets. (Prov. 5:16)

Accordingly, the Lord cries aloud to us: for, "He stood and cried out, if any man thirst, let him come unto me, and drink. He that believeth on me, as the Scripture saith, out of his belly shall flow rivers of living water." We are not obliged to delay to inquire what this meant, since the evangelist has explained it. For why the Lord said, "If any man thirst, let him come unto me, and drink;" and, "He that believeth on me, out of his belly shall flow rivers of living water;" the evangelist has subsequently explained, saying: "But this spake He of the Spirit which they that believe on Him should receive. For the Spirit was not yet given, because Jesus was not yet glorified." There is therefore an inner thirst and an inner belly, because there is an inner man. And that inner man is indeed invisible, but the outer man is visible; but yet better is the inner than the outer. And this which is not seen is the more loved; for it is certain that the inner man is loved more than the outer. How is this certain? Let every man prove it in himself. For although they who live ill may surrender their minds to the body, yet they do wish to live, and to live is the property of the mind only; and they who rule, manifest themselves more than those things that are ruled. Now it is minds that rule, bodies are ruled. Every man rejoices in pleasure, and receives pleasure by the body: but separate the mind from it, and nothing remains in the body to rejoice; and if there is joy of the body, it is the mind that rejoices. If it has joy of its dwelling, ought it not to have joy of itself? And if the mind has whereof it may have delight outside itself, does it remain without delights within? It is quite certain that a man loves his soul more than his body. I would say something further, by which it may more clearly appear to you, beloved, how much the mind is loved, and how it is preferred to the body. Those wanton lovers even, who delight in beauty of bodies, and are charmed by shapeliness of limbs, love the more when they are loved. For when a man loves, and finds that he is regarded with hatred, he feels more anger than liking. Why does he feel anger rather than liking? Because the love that he bestows is not given him in return. If, therefore, even the lovers of bodies desire to be loved in return, and this delights them more when they are loved, what shall we say of the lovers of minds? And if the lovers of minds are great, what shall we say of the lovers of God who makes minds beautiful? For as the mind gives grace to the body, so it is God that gives grace to the mind. For it is only the mind that causes that in the body by which it is loved; when the mind has left it, it is a corpse at which thou hast a horror; and how much soever thou mayest have loved its beautiful limbs, thou makest haste to bury it. Hence, the ornament of the body is the mind; the ornament of the mind is God. The Lord, therefore, cries aloud to us to come and drink, if we thirst within; and He says that when we have drunk, rivers of living water shall flow from our belly. The belly of the inner man is the conscience of the heart. Having drunk that water then, the conscience being purged begins to live; and drinking in, it will have a fountain, will be itself a fountain. What is the fountain, and what the river that flows from the belly of the inner man? Benevolence, whereby a man will consult the interest of his neighbor. For if he imagines that what he drinks ought to be only for his own satisfying, there is no flowing of living water from his belly; but if he is quick to consult for the good of his neighbor, then he becomes not dry, because there is a flowing. We will now see what it is that they drink who believe in the Lord; because we surely are Christians, and if we believe, we drink. And it is every man's duty to know in himself whether or not he drinks, and whether he lives by what he drinks; for the fountain does not forsake us if we forsake not the fountain.

(Tract. xxxii. 4) The belly of the inner man, is the heart's conscience. Let him drink from that water, and his conscience is quickened and purified; he drinks in the whole fountain, nay, becomes the very fountain itself. But what is that fountain, and what is that river, which flows from the belly of the inner man? The love of his neighbour. If any one, who drinks of the water, thinks that it is meant to satisfy himself alone, out of his belly there doth not flow living water. But if he does good to his neighbour, the stream is not dried up, but flows.
