‘It is done’, it is fixed and cannot be changed. We may ask, ‘what if’? We imagine a thousand contingencies that might arise. But the plan of God is fixed. All things have been anticipated by God; indeed all things have been ordained by God. This is the believer’s consolation. From God’s perspective, nothing is contingent.
Who can undo what he has done? Who can change past, present, or future? He is Alpha and Omega and besides him there is no other. There is no other who can interfere with his work. There is no other god with whom he need consult. There are no other parallel universes which might throw his plans into confusion. He is outside of everything, the eternal God, dependent on nothing, upholding all things. There are no uncertainties for him at any level as there are to man. Always the world brings forth new ideas to erode our confidence in the one true God. Always, we have to reassert that God is beyond and above and outside of all things. Puny human minds cannot begin to ascend to his heights. Far less can they imagine what is more ultimate than God. All man’s dreams fall far below the reality of the glory of God.
The word ‘fountain’ is means ‘spring’ or ‘living well’. In Revelation it is used of natural rather than man-made fountains. These are places where water naturally bubbles up from the ground. Used as a metaphor for life, it implies great abundance. As a spring sends up far more water than would ever be drunk or collected by those who live near it, so it is with the water of life. There is such plenty that all thought of shortage is dismissed. Never mind what time of day or what season of the year people go to the spring; they are guaranteed to find all that they need. Christ uses the same metaphor to speak of himself. He is an inexhaustible spring of life to those who come to him. This is water that whoever drinks shall never thirst. It is an infinite supply because Christ himself is infinite. Those who are thirsty in their souls can come to him from afar, confident that they will receive more than enough to compensate them for all they have left behind. He is a spring that gives life in the soul, eternal life. It is offered freely. No man can pay for it because it is beyond price. We come as bankrupts who must cast themselves on the mercy of our divine Benefactor. We come and beg for what we can never afford. But if we do so, we will receive riches that that the world cannot afford.
