Verse 4
How can a man be born when he is old? - It is probable that Nicodemus was pretty far advanced in age at this time; and from his answer we may plainly perceive that, like the rest of the Jews, and like multitudes of Christians, he rested in the letter, without paying proper attention to the spirit: the shadow, without the thing signified, had hitherto satisfied him. Our Lord knew him to be in this state, and this was the cause of his pointed address to him.
Verse 5
Of water and of the Spirit - To the baptism of water a man was admitted when he became a proselyte to the Jewish religion; and, in this baptism, he promised in the most solemn manner to renounce idolatry, to take the God of Israel for his God, and to have his life conformed to the precepts of the Divine law. But the water which was used on the occasion was only an emblem of the Holy Spirit. The soul was considered as in a state of defilement, because of past sin: now, as by that water the body was washed, cleansed, and refreshed, so, by the influences of the Holy Spirit, the soul was to be purified from its defilement, and strengthened to walk in the way of truth and holiness.
When John came baptizing with water, he gave the Jews the plainest intimations that this would not suffice; that it was only typical of that baptism of the Holy Ghost, under the similitude of fire, which they must all receive from Jesus Christ: see [Mat 3:11]. Therefore, our Lord asserts that a man must be born of water and the Spirit, i.e. of the Holy Ghost, which, represented under the similitude of water, cleanses, refreshes, and purifies the soul. Reader, hast thou never had any other baptism than that of water? If thou hast not had any other, take Jesus Christ's word for it, thou canst not, in thy present state, enter into the kingdom of God. I would not say to thee merely, read what it is to be born of the Spirit: but pray, O pray to God incessantly, till he give thee to feel what is implied in it! Remember, it is Jesus only who baptizes with the Holy Ghost: see [Joh 1:33]. He who receives not this baptism has neither right nor title to the kingdom of God; nor can he with any propriety be termed a Christian, because that which essentially distinguished the Christian dispensation from that of the Jews was, that its author baptized all his followers with the Holy Ghost.
Though baptism by water, into the Christian faith, was necessary to every Jew and Gentile that entered into the kingdom of the Messiah, it is not necessary that by water and the Spirit (in this place) we should understand two different things: it is probably only an elliptical form of speech, for the Holy Spirit under the similitude of water; as, in [Mat 3:3], the Holy Ghost and fire, do not mean two things, but one, viz. the Holy Ghost under the similitude of fire - pervading every part, refining and purifying the whole.
Verse 6
That which is born of the flesh is flesh - This is the answer to the objection made by Nicodemus in [Joh 3:4]. Can a man enter the second time into his mother's womb and be born? Our Lord here intimates that, were even this possible, it would not answer the end; for the plant will ever be of the nature of the seed that produces it - like will beget its like. The kingdom of God is spiritual and holy; and that which is born of the Spirit resembles the Spirit; for as he is who begat, so is he who is begotten of him. Therefore, the spiritual regeneration is essentially necessary, to prepare the soul for a holy and spiritual kingdom.
Verse 8
The wind bloweth - Though the manner in which this new birth is effected by the Divine Spirit, be incomprehensible to us, yet we must not, on this ground, suppose it to be impossible. The wind blows in a variety of directions - we hear its sound, perceive its operation in the motion of the trees, etc., and feel it on ourselves - but we cannot discern the air itself; we only know that it exists by the effects which it produces: so is every one who is born of the Spirit: the effects are as discernible and as sensible as those of the wind; but itself we cannot see. But he who is born of God knows that he is thus born: the Spirit itself, the grand agent in this new birth, beareth witness with his spirit, that he is born of God, [Rom 8:16]; for, he that believeth hath the witness in himself, [1Jn 4:13]; [1Jn 5:10]; [Gal 4:6]. And so does this Spirit work in and by him that others, though they see not the principle, can easily discern the change produced; for whatsoever is born of God overcometh the world, [1Jn 5:4].
Verse 9
How can these things be? - Our Lord had very plainly told him how these things could be, and illustrated the new birth by one of the most proper similes that could be chosen; but so intent was this great man an making every thing submit to the testimony of his senses that he appears unwilling to believe any thing, unless he can comprehend it. This is the case with many - they profess to believe because they comprehend; but they are impostors who speak thus: there is not a man in the universe that can fully comprehend one operation, either of God or his instrument nature; and yet they must believe, and do believe, though they never did nor ever can fully comprehend, or account for, the objects of their faith.
Verse 10
Art thou a master of Israel, etc. - Hast thou taken upon thee to guide the blind into the way of truth; and yet knowest not that truth thyself? Dost thou command proselytes to be baptized with water, as an emblem of a new birth; and art thou unacquainted with the cause, necessity, nature, and effects of that new birth? How many masters are there still in Israel who are in this respect deplorably ignorant; and, strange to tell, publish their ignorance and folly in the sight of the sun, by writing and speaking against the thing itself! It is strange that such people cannot keep their own secret. "But water baptism is this new birth." No. Jesus tells you, a man must be born of water and the Spirit; and the water, and its effects upon the body, differ as much from this Spirit, which it is intended to represent, and the effects produced in the soul, as real fire does from painted flame. "But I am taught to believe that this baptism is regeneration." Then you are taught to believe a falsity. The Church of England, in which perhaps you are a teacher or a member, asks the following questions, and returns the subjoined answers. "Q. How many sacraments hath Christ ordained in his Church?" "A. Two only, as generally necessary to salvation, that is to say, baptism and the supper of the Lord." "Q. How many parts are there in a sacrament?" "A. Two. The outward visible sign, and the inward spiritual grace." "Q. What is the outward visible sign, or form, in baptism?" "A. Water, wherein the person is baptized, In the name of the Father, and of the Son, and of the Holy Ghost." "Q. What is the inward and spiritual grace?" "A. A death unto sin, and a new birth unto righteousness; for being by nature born in sin, and the children of wrath, we are hereby made the children of grace."
Now, I ask, Whereby are such persons made the children of grace? Not by the water, but by the death unto sin, and the new birth unto righteousness: i.e. through the agency of the Holy Ghost, sin is destroyed, and the soul filled with holiness.
Verse 11
We speak that we do know - I and my disciples do not profess to teach a religion which we do not understand, nor exemplify in our conduct. A strong but delicate reproof to Nicodemus, who, though a master of Israel, did not understand the very rudiments of the doctrine of salvation. He was ignorant of the nature of the new birth. How wretched is the lot of that minister, who, while he professes to recommend the salvation of God to others, is all the while dealing in the meagre, unfruitful traffic of an unfelt truth! Let such either acquire the knowledge of the grace of God themselves, or cease to proclaim it.
Ye receive not our witness - It was deemed criminal among the Jews to question or depart from the authority of their teachers. Nicodemus grants that our Lord is a teacher come from God, and yet scruples to receive his testimony relative to the new birth, and the spiritual nature of the Messiah's kingdom.
Verse 12
If I have told you earthly things - If, after I have illustrated this new birth by a most expressive metaphor taken from earthly things, and after all you believe not; how can you believe, should I tell you of heavenly things, in such language as angels use, where earthly images and illustrations can have no place? Or, if you, a teacher in Israel, do not understand the nature of such an earthly thing, or custom of the kingdom established over the Jewish nation, as being born of baptism, practised every day in the initiation of proselytes, how will you understand such heavenly things as the initiation of my disciples by the baptism of the Holy Ghost and fire from heaven, if I should proceed farther on the subject?
Verse 13
No man hath ascended - This seems a figurative expression for, No man hath known the mysteries of the kingdom of God; as in [Deu 30:12]; [Psa 73:17]; [Pro 30:4]; [Rom 11:34]. And the expression is founded upon this generally received maxim: That to be perfectly acquainted with the concerns of a place, it is necessary for a person to be on the spot. But our Lord probably spoke to correct a false notion among the Jews, viz. that Moses had ascended to heaven, in order to get the law. It is not Moses who is to be heard now, but Jesus: Moses did not ascend to heaven; but the Son of man is come down from heaven to reveal the Divine will.
That came down - The incarnation of Christ is represented under the notion of his coming down from heaven, to dwell upon earth.
Which is in heaven - Lest a wrong meaning should be taken from the foregoing expression, and it should be imagined that, in order to manifest himself upon earth he must necessarily leave heaven; our blessed Lord qualifies it by adding, the Son of man who is in heaven; pointing out, by this, the ubiquity or omnipresence of his nature: a character essentially belonging to God; for no being can possibly exist in more places than one at a time, but He who fills the heavens and the earth.
Verse 14
As Moses lifted up - He shows the reason why he descended from heaven, that he might be lifted up, i.e. crucified, for the salvation of man. kind, and be, by the appointment of God, as certain a remedy for sinful souls as the brazen serpent elevated on a pole, [Num 21:9], was for the bodies of the Israelites, which had been bitten by the fiery serpents in the wilderness. It does not appear to me that the brazen serpent was ever intended to be considered as a type of Christ. It is possible to draw likenesses and resemblances out of any thing; but, in such matters as these, we should take heed that we go no farther than we can say, Thus it is written. Among the Jews, the brazen serpent was considered a type of the resurrection - through it the dying lived; and so, by the voice of God, they that were dead shall be raised to life. As the serpent was raised up, so shall Christ be lifted up: as they who were stung by the fiery serpents were restored by looking up to the brazen serpent, so those who are infected with and dying through sin are healed and saved, by looking up to and believing in Christ crucified. These are all the analogies which we can legitimately trace between the lifting up of the brazen serpent, and the crucifixion of Jesus Christ. The lifting up of the Son of man may refer to his mediatorial office at the right hand of God. See the note on [Num 21:9].
Verse 15
That whosoever believeth - Bp. Pearce supposes that this verse is only the conclusion of the 16th, and that it has been inserted in this place by mistake. The words contain the reason of the subject in the following verse, and seem to break in upon our Lord's argument before he had fully stated it. The words, μη αποληται αλλα, may not perish but, are omitted by some very ancient MSS. and versions.
Verse 16
For God so loved the world - Such a love as that which induced God to give his only begotten son to die for the world could not be described: Jesus Christ does not attempt it. He has put an eternity of meaning in the particle οὑτω, so, and left a subject for everlasting contemplation, wonder, and praise, to angels and to men. The same evangelist uses a similar mode of expression, [1Jn 3:1] : Behold, What Manner of love, ποταπην αγαπην, the Father hath bestowed upon us.
From the subject before him, let the reader attend to the following particulars.
First, The world was in a ruinous, condemned state, about to perish everlastingly; and was utterly without power to rescue itself from destruction.
Secondly, That God, through the impulse of his eternal love, provided for its rescue and salvation, by giving his Son to die for it.
Thirdly, That the sacrifice of Jesus was the only mean by which the redemption of man could be effected, and that it is absolutely sufficient to accomplish this gracious design: for it would have been inconsistent with the wisdom of God, to have appointed a sacrifice greater in itself, or less in its merit, than what the urgent necessities of the case required.
Fourthly, That sin must be an indescribable evil, when it required no less a sacrifice, to make atonement for it, than God manifested in the flesh.
Fifthly, That no man is saved through this sacrifice, but he that believes, i.e. who credits what God has spoken concerning Christ, his sacrifice, the end for which it was offered, and the way in which it is to be applied in order to become effectual.
Sixthly, That those who believe receive a double benefit:
1. They are exempted from eternal perdition - that they may not perish.
2. They are brought to eternal glory - that they may have everlasting life. These two benefits point out tacitly the state of man: he is guilty, and therefore exposed to punishment: he is impure, and therefore unfit for glory.
They point out also the two grand operations of grace, by which the salvation of man is effected.
1. Justification, by which the guilt of sin is removed, and consequently the person is no longer obnoxious to perdition.
2. Sanctification, or the purification of his nature, by which he is properly fitted for the kingdom of glory.
Verse 17
For God sent not, etc. - It was the opinion of the Jews that the Gentiles, whom they often term the world, עלמה olmah, and אומות העולם omoth haolam, nations of the world, were to be destroyed in the days of the Messiah. Christ corrects this false opinion; and teaches here a contrary doctrine. God, by giving his Son, and publishing his design in giving him, shows that he purposes the salvation, not the destruction, of the world - the Gentile people: nevertheless, those who will not receive the salvation he had provided for them, whether Jews or Gentiles, must necessarily perish; for this plain reason, There is but one remedy, and they refuse to apply it.
