John 3:8

The Spirit breatheth where he will. The Protestant translation has the wind: and so it is expounded by St. Chrysostom and St. Cyril on this verse; as if Christ compared the motions of the Holy Ghost to the wind, of which men can give so little account, whence it comes, or whither it goes. Yet many others, as St. Augustine, St. Ambrose and St. Gregory, understand this expression of the Holy Ghost, of whom it can only be properly said, that he breatheth where he will. (Witham)

There is a twofold admiration, that which is joined with infidelity, and that which is the effect of faith. Our Saviour forbids Nicodemus to marvel at the doctrine of regeneration, as strange and incredible, upon an imaginary impossibility supposed by him of the thing itself. But he that believes will judge that supernatural work of the Spirit, whereby a sinful man is made a partaker of the Divine nature, worthy of the highest admiration. And what our Saviour had said in the general before, that a man must be born again, he now particularly applies to Nicodemus, with those of his order, For Nicodemus would easily consent that the pagans, and possibly the vulgar Jews, had need of regeneration, to partake of the kingdom of God; but that the doctors of the law, (of which number himself was), esteemed the lights of the world, should be under the same necessity, was astonishing to him. Therefore our Saviour, to undeceive and humble him, saith, for that all are defiled with the corruption that is universal to mankind.

[d.] This change is illustrated by two comparisons. First, The regenerating work of the Spirit is compared to water, v. 5. To be born again is to be born of water and of the Spirit, that is, of the Spirit working like water, as (Matt 3 11) with the Holy Ghost and with fire means with the Holy Ghost as with fire. 1. That which is primarily intended here is to show that the Spirit, in sanctifying a soul, (1.) Cleanses and purifies it as water, takes away its filth, by which it was unfit for the kingdom of God. It is the washing of regeneration, Tit 3 5. You are washed, 1 Cor 6 11. See Ezek 36 25. (2.) Cools and refreshes it, as water does the hunted hart and the weary traveller. The Spirit is compared to water, ch. 7 38, 39; Isa 44 3. In the first creation, the fruits of heaven were born of water (Gen 1 20), in allusion to which, perhaps, they that are born from above are said to be born of water. 2. It is probable that Christ had an eye to the ordinance of baptism, which John had used and he himself had begun to use, "You must be born again of the Spirit," which regeneration by the Spirit should be signified by washing with water, as the visible sign of that spiritual grace: not that all they, and they only, that are baptized, are saved; but without that new birth which is wrought by the Spirit, and signified by baptism, none shall be looked upon as the protected privileged subjects of the kingdom of heaven. The Jews cannot partake of the benefits of the Messiah's kingdom, they have so long looked for, unless they quit all expectations of being justified by the works of the law, and submit to the baptism of repentance, the great gospel duty, for the remission of sins, the great gospel privilege. Secondly, It is compared to wind: The wind bloweth where it listeth, so is every one that is born of the Spirit, v. 8. The same word (pneuma) signifies both the wind and the Spirit. The Spirit came upon the apostles in a rushing mighty wind (Acts 2 2), his strong influences on the hearts of sinners are compared to the breathing of the wind (Ezek 37 9), and his sweet influences on the souls of saints to the north and south wind, Cant 4 16. This comparison is here used to show, 1. That the Spirit, in regeneration, works arbitrarily, and as a free agent. The wind bloweth where it listeth for us, and does not attend our order, nor is subject to our command. God directs it; it fulfils his word, Ps 148 8. The Spirit dispenses his influences where, and when, on whom, and in what measure and degree, he pleases, dividing to every man severally as he will, 1 Cor 12 11. 2. That he works powerfully, and with evident effects: Thou hearest the sound thereof; though its causes are hidden, its effects are manifest. When the soul is brought to mourn for sin, to groan under the burden of corruption, to breathe after Christ, to cry Abba—Father, then we hear the sound of the Spirit, we find he is at work, as Acts 9 11, Behold he prayeth. 3. That he works mysteriously, and in secret hidden ways: Thou canst not tell whence it comes, nor whither it goes. How it gathers and how it spends its strength is a riddle to us; so the manner and methods of the Spirit's working are a mystery. Which way went the Spirit? 1 Kings 22 24. See Eccl 11 5, and compare it with Ps 139 14.

(1.) As pertinently answered to Nicodemus's address. Jesus answered, v. 3. This answer was wither, [1.] A rebuke of what he saw defective in the address of Nicodemus. It was not enough for him to admire Christ's miracles, and acknowledge his mission, but he must be born again. It is plain that he expected the kingdom of heaven, the kingdom of the Messiah now shortly to appear. He is betimes aware of the dawning of that day; and, according to the common notion of the Jews, he expects it to appear in external pomp and power. He doubts not but this Jesus, who works these miracles, is either the Messiah or his prophet, and therefore makes his court to him, compliments him, and so hopes to secure a share to himself of the advantages of that kingdom. But Christ tells him that he can have no benefit by that change of the state, unless there be a change of the spirit, of the principles and dispositions, equivalent to a new birth. Nicodemus came by night: "But this will not do," saith Christ. His religion must be owned before men; so Dr. Hammond. Or, [2.] A reply to what he saw designed in his address. When Nicodemus owned Christ a teacher come from God, one entrusted with an extraordinary revelation from heaven, he plainly intimated a desire to know what this revelation was and a readiness to receive it; and Christ declares it.

Verses 1-8 Nicodemus was afraid, or ashamed to be seen with Christ, therefore came in the night. When religion is out of fashion, there are many Nicodemites. But though he came by night, Jesus bid him welcome, and hereby taught us to encourage good beginnings, although weak. And though now he came by night, yet afterward he owned Christ publicly. He did not talk with Christ about state affairs, though he was a ruler, but about the concerns of his own soul and its salvation, and went at once to them. Our Saviour spoke of the necessity and nature of regeneration or the new birth, and at once directed Nicodemus to the source of holiness of the heart. Birth is the beginning of life; to be born again, is to begin to live anew, as those who have lived much amiss, or to little purpose. We must have a new nature, new principles, new affections, new aims. By our first birth we were corrupt, shapen in sin; therefore we must be made new creatures. No stronger expression could have been chosen to signify a great and most remarkable change of state and character. We must be entirely different from what we were before, as that which begins to be at any time, is not, and cannot be the same with that which was before. This new birth is from heaven, ch. 1:13 , and its tendency is to heaven. It is a great change made in the heart of a sinner, by the power of the Holy Spirit. It means that something is done in us, and for us, which we cannot do for ourselves. Something is wrong, whereby such a life begins as shall last for ever. We cannot otherwise expect any benefit by Christ; it is necessary to our happiness here and hereafter. What Christ speak, Nicodemus misunderstood, as if there had been no other way of regenerating and new-moulding an immortal soul, than by new-framing the body.…
