First, It showeth us that it is grace alone that saveth the sinner, pure grace, grace that admits of nothing of ours to be in the least a helper in the matter of our happiness; we are 'justified freely by his grace, through the redemption that is in Christ Jesus.' As he saith by the prophet, 'I will pour CLEAN water upon you, and ye shall be clean, and from all your idols will I cleanse you' (Eze 36:25).[22] 'Not for your sakes do I this, saith the Lord. Be ye ashamed and confounded for all your own evil ways, O house of Israel' (vv 32,33). It is clean water, indeed-it is clear in the nature of it, clear in the gift of it, and clear in the working of it. It washeth freely, thoroughly, and perfectly. 'From all your idols will I cleanse you' (v 25; 16:9; Rev 21:8).
Second, This word pure, and clear as crystal, it also showeth us that at the day of New Jerusalem, the doctrine of grace shall be cleansed from all those dirty and muddy inventions that sin, Satan, and the wisdom of this world hath thrown into this river, and into its goodly crystal streams; I say at this day they shall not come near it, neither shall the rubbish they have already cast into it any more be there for ever. 'I will destroy all the beasts thereof [the beastly men he means] from beside the great waters, neither shall the foot of man trouble them any more, nor the hoofs of beasts trouble them. Then will I make their waters deep, and cause the rivers to run like oil, saith the Lord God' (Eze 32:13,14).
'And he SHEWED me a pure river of water of life, clear as crystal,' &c. In that he saith he saw this river, he giveth us in a mystery also to understand how openly and plainly this river shall in all its crystal streams and currents be apprehended and seen by the children of this city; for in this vision he doth as it were represent in his person the children of New Jerusalem; as God said to Ezekiel in another case, 'Thou shalt be a sign,' 'and they shall do as thou hast done' (24:22,27). So here, I saw, saith John, a pure river of water of life. I am in this a sign to the house of the Israel of God, and to the inhabitants of this city; they shall do as I have done, and shall also see as I have seen. As saith the church and people of this city, 'As we have heard, so have we seen, in the city of the Lord of hosts' (Psa 48:8). And hence it is called an open fountain, because it shall be no more shut up or kept close for ever (Zech 13:1,2).
[Whither this water goes and its extension.]
'And he showed me a pure river of water of life, clear as crystal, PROCEEDING out of the throne of God.' This word, proceeding, hath also in it two things: First, An implicit declaration whither it goes; and, Second, A discovery of its gradual extension to those to whom it goes.
First. Touching to whom, or whither it goes, it is let out both to the Jews and Gentiles indifferently; and so it never yet was since the foundations of the Jewish church; for in the time of the Old Testament it did run to the Jews in special, and in the time of the New Testament, hitherto, unto us the Gentiles in special. O! but now it shall in this manner be extended to sinners no longer; not now to the Jews without the Gentiles, nor again to them without the Jews, but equally and alike to both, and on them both it shall work alike effectually. 'It shall be in that day,' saith the prophet, 'that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea' (Zech 14:8). By 'living waters' here, you are to understand the same with this in the text; by 'the former sea,' the people of the Jews, for they were God's former people; and by 'hinder sea,' the people of the Gentiles, for they are the younger son. And because the whole world consisteth of these two people, therefore Ezekiel in his vision puts them both together, calling them the fish of one great sea, to which this water of life shall run, and upon whose fish it shall have a like operation, even to heal them, and make them live, without respect either to this or that party. 'It shall come to pass that the fishers,' that is, the gospel ministers, 'shall stand upon it,' the rivers, 'from En-gedi even to En-eglaim; they shall be a place to spread forth nets; their fish shall be according to their kinds, as the fish of the great sea, exceeding many' (Eze 47:10). As another prophet saith, 'The abundance of the sea shall be converted to thee' (Isa 60:5). Thus much touching whither this water goes.
[Second.] And now to come to the manner of the extension of it, in the way of its proceeding. A thing that proceeds, it doth what it doth gradually, that is, by degrees. First, it comes or goes so far, and then further, and afterwards further than that, till at last it ascends to the height and uppermost degree that is allotted for its perfection. All which the Holy Ghost would have us gather out of this word, 'it proceedeth,' or that John saw this holy water 'proceeding.' The which the prophet Ezekiel in a mystery unfoldeth to us, saying, the first time he passed over this water it was up but to his ankles; the second time he passed through, it proceeded to his knees; the third time, to his loins; and last of all, became a river to swim in (Eze 47:1-3).
1. It is but up to the ankles, that is, but shallow; and signifies that, first, the soul is but a little child in God's things, such as the apostle calls babes, children, 'little children' (1 John 2:12).
2. Then from the ankles it proceeds to the knees, that is, somewhat higher than the ankles; and signifieth that the Christian groweth from a child to a young and strong man, one that is now gotten deeper into the things of God, and that is able to tug with and overcome the wicked ones (1 John 2:13).
3. After this it proceeds higher, even up to the loins; this signifies that as grace makes men children of God, and his young men, so also it maketh them fathers and ancients in his church; it makes them grave, knowing, solid guides, and unfolders of the mysteries of the kingdom; these are such as are instructed into the kingdom of God, and that can bring out of their treasury things new and old.
