More closely, where it is called 'living water,' 'that living water,' and 'water springing up into everlasting life' (John 4:10,11,14, 7:38).
Then more openly or expressly it is called 'the Spirit of life.' 'And after three days and an half, the Spirit of life from God entered into them, and they stood upon their feet' (Rev 11:11).
From hence, therefore, I conclude, that by these terms, water of life, is meant the Spirit of grace, or the Spirit and grace of the gospel. And the terms are such as are most apt to set forth the Spirit and grace of the gospel by: for,
[First. The term WATER.]
1. By this term, WATER, an opposition to sin is presented unto us. Sin is compared to water, to deadly waters, and man is said to drink it, as one that drinketh waters. 'How much more abominable and filthy is man, which drinketh iniquity like water?' (Job 15:16). So, then, that grace and the Spirit of grace is compared to water, it is to show what an antidote grace is against sin; it is, as I may call it, counter poison to it. It is that ONLY thing by the virtue of which sin can be forgiven, vanquished, and overcome.
2. By this term WATER, you have an opposition also to the curse, that is due to sin, presented unto you. The curse, is compared to water; the remedy is compared to water. Let the curse come into the bowels of the damned, saith the psalmist, like water (Psa 109:18). The grace of God also, as you see, is compared to water. The curse is burning; water is cooling: the curse doth burn with hell-fire; cooling is by the grace of the holy gospel: but they that overstand the day of grace, shall not obtain to cool their tongues so much of this water as will hang on the tip of one's finger (Luke 16:24,25).[2]
3. Water is also of a spreading nature, and so is sin; wherefore sin may for this also be compared to water. It overspreads the whole man, and infects every member; it covereth all as doth water. Grace for this cause may be also compared to water; for that it is of a spreading nature, and can, if God will, cover the face of the whole earth; of body and soul.
4. Sin is of a fouling, defiling nature; and grace is of a washing, cleansing nature; therefore grace, and the Spirit of grace, is compared to water. 'I will,' saith God, 'sprinkle clean water upon you, [my Spirit, v 27] and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you' (Eze 36:25).
5. Water; the element of water naturally descends to and abides in low places, in valleys and places which are undermost; and the grace of God and the Spirit of grace is of that nature also; the hills and lofty mountains have not the rivers running over the tops of them; no, though they may run 'among them.' But they run among the valleys: and 'God resisteth the proud, and giveth grace unto the humble,' 'to the lowly' (John 4:6; 1 Peter 5:5; Prov 3:34).
6. The grace of God is compared to water, for that it is it which causeth fruitfulness; water causeth fruitfulness, want of water is the cause of barrenness; and this is the reason why the whole world is so empty of fruit to Godward, even because so few of the children of men have the Spirit of grace in their hearts. But,
