These words are part of that description that one of the seven angels, which had the seven vials full of the seven last plagues, gave unto John of the New Jerusalem, or of the state of that gospel church, that shall be in the latter days (Rev 21:9). Wherefore he saith, 'And he showed me'; HE, the angel, showed me it.
In the text we have these things to consider of,
FIRST. The matter, the subject matter of the text, and that is the water of life. 'He showed me the water of life.' SECOND. We have also here the quantity of this water showed to him, and that is under the notion of a river: 'He showed me a river of water of life.' THIRD. He shows him also the head, or well-spring, from whence this river of water of life proceeds, and that is, 'the throne of God and of the Lamb.' 'He showed me a river of water of life, proceeding out of the throne of God, and of the Lamb.' FOURTH. We have also here the nature and quality of this water; it is pure, it is clear as crystal: 'And he showed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb.'
[THE WATER OF LIFE.]
[FIRST.] We will begin with the first of these, to wit, with the matter, the subject matter of the text, which is, THE WATER OF LIFE. These words, water of life, are metaphorical, or words by which a thing most excellent is presented to and amplified before our faces; and that thing is the Spirit of grace, the Spirit and grace of God. And the words, water of life, are words most apt to present it to us by; for what is more free than water, and what more beneficial and more desirable than life? Therefore I say it is compared to, or called, the water of life. He showed me the water of life.
That it is the Spirit of grace, or the Spirit and grace of God, that is here intended: consider, FIRST, the Spirit of grace is in other places compared to water: and, SECOND, it is also called the Spirit of life. Just as here it is presented unto us, 'He showed me the water of life.'
FIRST. The spirit of grace is compared to water. 'Whosoever,' saith the Lamb, 'drinketh of the water that I shall give him, shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life' (John 4:14). What can here by water be intended, but the Spirit of grace that this poor harlot, the woman of Samaria, wanted, although she was ignorant of her want, as also of the excellency thereof? Which water also is here said to be such as will spring up, in them that have it, as a well into everlasting life.
Again, 'In the last day, that great day of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me and drink.' But of what? Why of his rivers of living waters. But what are they? Why he answers, 'This spake he of the Spirit, which they that believe on him should receive' (John 7:37-39).
Yes, the prophets and servants of God in the Old Testament, did take this water of life for the Spirit of grace that should in the latter days be poured out into the church. Hence, Isaiah calls water God's Spirit and blessing, and Zechariah, the Spirit of grace. 'I will pour water upon him that is thirsty, and floods upon the dry ground: I will pour my Spirit upon thy seed, and my blessing upon thine offspring' (Isa 44:3). And Zechariah saith, 'I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplication,—and they shall mourn,' &c. (Zech 12:10). Behold, in all these places the Spirit of grace is intended, and for our better understanding it is compared to water, to a well of water, to springs of water, and to floods of water.
SECOND. It is also called the Spirit of life, [either] more closely, [or] more openly.
