Our Lord, in the subsequent part of this conversation, again touches upon this great metaphor, and suggests one or two characteristics, blessings, and excellences of it. 'It shall be _in_ him,' it is something that we may carry about with us in our hearts, inseparable from our being, free from all possibility of being filched away by violence, being rent from us by sorrows, or even being parted from us by death. What a man has outside of him he only seems to have. Our only real possessions are those which have passed into the substance of our souls. All else we shall leave behind. The only good is inward good; and this water of life slakes our thirst because it flows into the deepest place of our being, and abides there for ever. Oh! you that are seeking your satisfaction from fountains that remain outside of you after all your efforts, learn that all of them, by reason of their externality, will sooner or later be 'broken cisterns that can hold no water.' And I beseech you, if you want rest for your souls and stilling for their yearnings, look for it there, where only it can be found, in Him, who not only dwells in the heavens to rule and to shower down blessings, but enters into the waiting heart and abides there, the inward, and therefore the only real, possession and riches. 'It shall be in him a fountain of water.' It is 'springing up'—with an immortal energy, with ever fresh fulness, by its own inherent power, needing no pumps nor machinery, but ever welling forth its refreshment, an emblem of the joyous energy and continual freshness of vitality, which is granted to those who carry God in their hearts, and therefore can never be depressed beyond measure, nor ever feel that the burden of life is too heavy to bear, or its sorrows too sharp to endure. It springs up 'into eternal life,' for water must seek its source, and rise to the level of its origin, and this fountain within a man, that reaches up ever towards the eternal life from which it came, and which it gives to its possessor, will bear him up, as some strong spring will lift the clods that choked its mouth, will bear him up towards the eternal life which is native to it, and therefore native to him. Brethren, no man is so poor, so low, so narrow in capacity, so limited in heart and head, but that he needs a whole God to make him restful. Nothing else will. To seek for satisfaction elsewhere is like sailors who in their desperation, when the water-tanks are empty, slake their thirst with the treacherous blue that washes cruelly along the battered sides of their ship. A moment's alleviation is followed by the recurrence, in tenfold intensity, of the pangs of thirst, and by madness, and death. Do not drink the salt water that flashes and rolls by your side when you can have recourse to the fountain of life that is with God.
