God’s word and those before me say it best:
Jesus said to her, “Everyone who drinks of this water will be thirsty again, but whoever drinks of the water that I will give him will never be thirsty again. The water that I will give him will become in him a spring of water welling up to eternal life.” – John 4:13-14
For what is the sum and substance of these simple words? It is this: Christ is that Fountain of living water, which God has graciously provided for thirsting souls. From Him, as out of the rock smitten by Moses, there flows an abundant stream for all who travel through the wilderness of this world. In Him, as our Redeemer and Substitute, crucified for our sins and raised again for our justification, there is an endless supply of all that men can need: pardon, absolution, mercy, grace, peace, rest, relief, comfort and hope. – J. C. Ryle
My people have committed two sins: They have forsaken me, the spring of living water, and have dug their own cisterns, broken cisterns that cannot hold water. Jeremiah 2:13
Men are in a restless pursuit after satisfaction in earthly things. They will exhaust themselves in the deceitful delights of sin, and, finding them all to be vanity and emptiness, they will become very perplexed and disappointed. But they will still continue their fruitless search.
Though wearied, they still stagger forward under the influence of spiritual madness, and though there is no result to be reached except that of everlasting disappointment, yet they press forward. They have no forethought for their eternal state; the present hour absorbs them. They turn to another and another of earth’s broken cisterns, hoping to find water where not a drop was ever discovered yet. – Spurgeon
There is in Him an all-sufficiency of grace and strength; all our springs are in Him and our streams from him; to forsake Him is, in effect, to deny this. He has been to us a bountiful benefactor, a fountain of living waters, overflowing, ever flowing, in the gifts of his favor; to forsake Him is to refuse to acknowledge His kindness and to withhold that tribute of love and praise which His kindness calls for.
Those who forsake Him cheat themselves, they forsook their own mercies, but it was for lying vanities. They took a great deal of pains to hew themselves out cisterns, to dig pits or pools in the earth or rock which they would carry water to, or which should receive the rain; but they proved broken cisterns, false at the bottom, so that they could hold no water. When they came to quench their thirst there they found nothing but mud and mire, and the filthy sediments of a standing lake. Such idols were to their worshippers, and such a change did those experience who turned from God to them.
If we make an idol of any creature – wealth, or pleasure, or honor, if we place our happiness in it, and promise ourselves the comfort and satisfaction in it which are to be had in God only, if we make it our joy and love, our hope and confidence, we shall find it a cistern, which we take a great deal of pains to hew out and fill, and at the best it will hold but a little water, and that dead and flat, and soon corrupting and becoming nauseous. No, it is a broken cistern, which cracks and cleaves in hot weather, so that the water is lost when we have most need of it. Let us therefore with purpose of heart cleave to the Lord only, for where else shall we go? He has the words of eternal life. – Puritan
