There is, besides this, another blessing that comes to us by this living water, and that is, the blessing of communion. All the warmth that we have in our communion, it is the warmth of the Spirit: when a company of saints are gathered together in the name of Christ, to perform any spiritual exercise, and their souls be edified, warmed, and made glad therein, it is because this water, this river of water of life, has, in some of the streams thereof, run into that assembly (Jer 31:12,13). Then are Christians like those that drink wine in bowls, merry and glad; for that they have drank into the Spirit, and had their souls refreshed with the sweet gales and strong wine thereof. This is the feast that Isaiah speaks of, when he saith, 'In this mountain shall the Lord of hosts make unto all people a feast of fat things, a feast of wines on the lees, of fat things full of marrow, of wines on the lees well refined' (Isa 25:6). This is called in another place, 'the communion of the Holy Ghost' (2 Cor 13:14). Now he warmeth spirits, uniteth spirits, enlighteneth spirits; revives, cherisheth, quickeneth, strengtheneth graces; renews assurances, brings old comforts to mind, weakens lusts, emboldeneth and raiseth a spirit of faith, of love, of hope, of prayer, and makes the Word a blessing, conference a blessing, meditation a blessing, and duty very delightful to the soul. Without this water of life, communion is weak, flat, cold, dead, fruitless, lifeless; there is nothing seen, felt, heard, or understood in a spiritual and heart-quickening way. Now ordinances are burdensome, sins strong, faith weak, hearts hard, and the faces of our souls dry, like the dry and parched ground.
This drink also revives us when tempted, when sick, when persecuted, when in the dark, and when we faint for thirst. The life of religion is this water of life: where that runs, where that is received, and where things are done in this spirit, there all things are well; the church thrifty, the soul thrifty, graces thrifty, and all is well. And this hint I thought convenient to be given of this precious water of life, that is, with reference to the operative quality of it.
[The other qualities of this water.]
SECOND. I shall come, in the next place, to speak of it, as to the other descriptions which John doth give us of it. He says it is, First, pure; Second, clear; Third, clear to a comparison: 'And he showed me a pure river of water of life, clear as crystal.'
[First. The purity of this water.]
1. You read here that this water of life is PURE, that is, alone without mixture, for so sometimes that word PURE is to be understood. As where it saith, pure, 'pure olive oil' (Exo 27:20). 'Pure frankincense' (Exo 30:34). 'Pure gold' (Exo 25:11,17). 'Pure blood of the grape' (Deut 32:14), and the like. So then, when he saith, 'he showed me a pure river of water of life,' it is as if he had said he showed me a river of water that was all living, all life, and had nothing in it but life. There was no death, or deadness, or flatness in it; or, as he saith a little after, 'and there shall be no more curse.' A pure river. There is not so much as a grudge, or a piece of an upbraiding speech found therein. There is in it nothing but heart, nothing but love, nothing but grace, nothing but life. 'The gifts and calling of God are without repentance' (Rom 11:29).
2. PURE is sometimes set in opposition to show or appearance; as where he says, 'the stars are not pure' (Job 25:5). That is, not so without mixture of darkness, as they seem to be: so again, 'If thou wert pure and upright' (Job 8:6): that is, as thou seemest to be, or as thou wouldst have us believe thou art.
Now, take pure in this sense here, and then the meaning is, it is grace without deceit, without guile; its show and its substance are the same; it has nothing but substance in it; it is indeed what it seems to be in bulk; it is a river in show and a river indeed. It comes from God and from his throne in appearance, and really it comes from his very heart.
The great fear of the tempted is, that there is not so much grace in God, and that he is not so free of it as some scriptures seem to import. But this word PURE is levelled against such objections and objectors, for the destroying of their doubts, and the relieving of their souls. There is no fraud, nor guile, nor fable in the business; for though God is pleased to present us with his grace under the notion of a river, it is not to delude our fancies thereby; but to give us some small illustration of the exceeding riches of his grace, which as far, for quantity, outstrips the biggest rivers, as the most mighty mountain doth the least ant's egg or atom in the world.
3. But, again, this word PURE is set in opposition to that which is hurtful and destructive: 'I am pure from the blood of all men,' that is, I have hurt nobody (Acts 20:26). 'The wisdom that is from above is first pure,' it is not hurtful (James 3:17). Do you count them pure with the wicked balances? how can that be, since they are hurtful? (Micah 6:11).
