Commentary on the Gospel According to John John Calvin
Commentary on John poverty to seek relief. Hence it arises that many persons do not stir a foot, but wretchedly wither and decay, and there are even very many who are not affected by a perception of their emptiness, until the Spirit of God, by his own fire, kindle hunger and thirst in their hearts. It belongs to the Spirit, therefore, to cause us to desire his grace.
As to the present passage, we ought to observe, first, that none are called to obtain the riches of the Spirit but those who burn with the desire of them. For we know that the pain of thirst is most acute and tormenting, so that the very strongest men, and those who can endure any amount of toil, are overpowered by thirst. And yet he invites the thirsty rather than the hungry, in order to pursue the metaphor which he afterwards employs in the word water and the word drink, that all the parts of the discourse may agree with each other. And I have no doubt that he alludes to that passage in Isaiah, All that thirst, come to the waters, (Isaiah 55:1.) For what the Prophet there ascribes to God must have been at length fulfilled in Christ, as also that which the blessed Virgin sung, that those who are rich and full he sendeth empty away, (Luke 1:53.)
He therefore enjoins us to come direct to himself, as if he had said, that it is he alone who can fully satisfy the thirst of all, and that all who seek even the smallest alleviation of their thirst anywhere else are mistaken, and labor in vain.
And let him drink. To the exhortation a promise is added; for though the word — let him drink — conveys an exhortation, still it contains within itself a promise; because Christ testifies that he is not a dry and worn-out cistern, but an inexhaustible fountain, which largely and abundantly supplies all who will come to drink Hence it follows that, if we ask from him what we want, our desire will not be disappointed.
38. He who believeth in me. He now points out the manner of coming, which is, that we must approach, not with the feet, but by faith; or rather, to come is nothing else than to believe, at least, if you define accurately the word believe; as we have already said that we believe in Christ, when we embrace him as he is held out to us in the Gospel, full of power, wisdom, righteousness, purity, life, and all the gifts of the Holy Spirit. Besides, he now confirms more plainly and fully the promise which we lately mentioned; for he shows that he has a rich abundance to satisfy us to the full.
Out of his belly shall flow rivers of living water. The metaphor appears, no doubt, to be somewhat harsh, when he says that rivers of living water shall flow out of the belly of believers; but there can be no doubt as to the meaning, that they who believe shall suffer no want of spiritual blessings. He calls it living water, the fountain of which never grows dry, nor ceases to flow continually. As to the word rivers being in the plural number, I interpret it as denoting the diversified graces of the Spirit, which are necessary for the spiritual life of the soul. In short, the perpetuity, as well as the abundance,
