Now, with regard to the first point, let me remind you to begin with, that the idea of the word here is not that which we attach to a well, but that which we attach to a spring. It does not describe the source of salvation as being a mere reservoir, still less as being a created or manufactured thing; but there lies in it the deep idea of a source from which the water wells up by its own inward energy. Then, when we have got that explanation, and the deep, full, pregnant meaning of the word salvation as a thing past, a thing present, a thing future, a thing which negatively delivers a man from all sin and sorrow, and a thing which positively endows a man with beauty, happiness, and holiness--when we have got that, then the question next cries aloud for answer--this well-spring of salvation, is--what? Who? And the first answer and the last answer is GOD--GOD HIMSELF. It is no mere bit of drapery of the prophet's imagery, this well-spring of salvation; it is something much more substantial, much deeper than that. You remember the old psalm, 'With Thee is the fountain of life: in Thy light shall we see light'; and what David and John after him called life, Isaiah and Paul after him calls salvation. And you remember too, no doubt, the indictment of another of the prophets, laying hold of the same metaphor in order to point to the folly and the suicide of all godless living: 'My people have committed two evils: they have forsaken Me, the fountain of living waters, and they have hewn out for themselves broken cisterns.' They were manufactured articles, and because they were made they could be cracked, but the fountain, because it rises by its own inherent energy, springing up into everlasting life, is all-sufficient. God Himself is the well-spring of salvation.
