John 4:13-14

Whosoever drinketh of this water, &c.— "This water can allay the pain of thirst only for a little while, because, though it be drank ever so plentifully, the appetite will return again; but whosoever drinketh of the water that I shall give him, shall never thirst; shall at no time be subject to any vehement painful sensations, arising from unmortified irregular appetites; but the water, &c. shall be in him a well of water, springing up into everlasting life; shall yield him divine satisfaction now, and shall be the source of happiness to the faithful to all eternity in heaven; where they shall feel none of the bodily appetites or wants so troublesome to men in this life." Thus Jesus, under the image of living, or spring water, taken from the well beside which he was sitting, beautifully described, as his manner was, the efficacy of the influences of the Spirit of God; for, as water quenches thirst, so these, by quieting the agitation, and cooling the fervency of earthly desires, beget an unspeakable inward peace. By this image he also set forth the plenitude and perpetuity of the celestial joys, flowing from holy dispositions, produced by the influences of the Spirit of God. For these, by an innate power, satisfying all the capacities and desires of the soul, render it so completely happy, that it is not able to form a wish or a thought of any thing better.
