(12) Earthly things—i.e., things upon earth, having the sphere of their action upon earth. These are not necessarily restricted to the subjects of this interview. The context includes previous witness borne by Him, and there must have been much which is unrecorded. (Comp. John 2:23.) But the new birth is not excluded from “earthly things,” because it is the entrance to a life which, while it is spiritual, is still a life upon earth.

Heavenly things, in the same way, are things which have the sphere of their action in heaven, the full development of the spiritual life, of which the birth only is on earth; the divine counsels of redemption; the Messianic mysteries, of which this ruler of Israel does not understand even the initiation. Comp. the question in the Wisdom of Solomon, “What man is he that can know the counsel of God? or who can think what the will of the Lord is? . . . And hardly do we guess aright at things that are upon earth, and with labour do we find the things that are before us: but the things that are in heaven who hath searched out?” (John 9:13; John 9:16).

The earthly things are the elements of spiritual knowledge, having their test in the moral sense and in their fitness to supply the spiritual wants of man. When these elements are learnt, the mind is then, and then only, fitted to receive heavenly things. The teaching can only proceed step by step from the known to the unknown; but if the will refuses or the intellect neglects to know the knowable, the man cuts himself off from the power to receive truth. The message from the spirit-world has come, and others read it; but he has not learnt the alphabet. (Comp. Note on John 16:12.)

John 3:12-13. If I have told you earthly things — As the truths which I have taught you concerning the spiritual nature of God’s kingdom, and the qualifications of his subjects, may properly be termed, because they are capable of being represented to you in a familiar way, and of being illustrated by such obvious and well-known similitudes as to be rendered thereby perfectly plain and easy to be understood. Or, by earthly things, he might mean things to be experienced and enjoyed on earth, such as the new birth and the present privileges of the children of God. And ye believe not — Even these; how shall ye believe if I tell you of heavenly things — If I should go on to teach you other doctrines, much more mysterious and sublime, and not capable of being thus illustrated and explained? Our Lord has been thought by some to refer here to those sublime and heavenly doctrines which were afterward revealed, such as the eternity of the Son, the fulness of the Godhead dwelling in him bodily, the unity of the Father, Son, and Spirit, and those other mysteries of godliness that are above the reach of human reason, and cannot be illustrated by earthly things. It is more probable, however, as Dr. Doddridge observes, that he more immediately refers “to the doctrines which he mentions in the remaining part of his discourse to Nicodemus — of his descent from heaven to instruct us in the things of God, and be united to the human nature here below, while, by his divine nature, he still continued to be present above, — of the design for which he came into the world, to be lifted up upon the cross, that he might save us from our sins, — of everlasting life, and happiness to be obtained by faith in his death, — and of the condemnation of all those that should reject him; which may be counted as the deep things of God, which he reveals unto us by his Spirit, and which the natural man, who disregards that Spirit, receiveth not, for they are foolishness unto him, 1 Corinthians 2:10; 1 Corinthians 2:14.” And no man, &c. — As if he had said, For here you must rely on my single testimony, whereas in the other points, termed earthly things, you have a cloud of witnesses. Or the connection and sense may be, Yet the truth of my doctrine concerning these heavenly things you will have no just reason to suspect, considering whence it comes, and who it is that reveals it. For no man hath ascended up to heaven — To search into the secret counsels of God, and to obtain an intimate and perfect knowledge of his mind and will; but he that came down from heaven — Qualified and commissioned in the most extraordinary manner to reveal them, as far as is proper, to mankind; even the Son of man which is in heaven — Is present there by his divine nature, which fills both heaven and earth, even while he is here on earth as to his human nature. This is a plain instance of what is usually termed the communication of properties between Christ’s divine and human nature, whereby what is proper to the divine nature is spoken concerning the human; and what is proper to the human, is spoken of the divine. “Beza, and some others, suppose that the present tense, (ων, who is,) is here put for the past, (ην, who was,) of which construction we have some examples, particularly John 9:25. Accordingly they translate the clause, The Son of man, who was in heaven: but the common translation may be retained, [and interpreted,] thus: Moses, your lawgiver, did not ascend into heaven; he only went up to mount Sinai, and that but for a few days, that he might receive the law from God. Whereas, the Son of man, (this was one of the Messiah’s titles,) who is come down from heaven, (ο εκ του ουρανου καταβας,) who is commissioned by God in an extraordinary manner, to reveal his will to men, and in respect of whose commission, all the other messengers of God may be said to have been of the earth: (see John 3:31; Hebrews 12:25 :) he hath ascended up to heaven — Hath received the clearest and most extensive views of spiritual things; hath penetrated into the recesses of the divine counsels; (see Proverbs 30:3-4;) nay, is, at present, in heaven, is with God, is conscious of all his gracious purposes toward men, consequently must be a messenger of much higher dignity than Moses, or Elijah, or any of the prophets, for whom you entertain so great a regard.” — Macknight.

3:1-8 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. But he acknowledged his ignorance, which shows a desire to be better informed. It is then further explained by the Lord Jesus. He shows the Author of this blessed change. It is not wrought by any wisdom or power of our own, but by the power of the blessed Spirit. We are shapen in iniquity, which makes it necessary that our nature be changed. We are not to marvel at this; for, when we consider the holiness of God, the depravity of our nature, and the happiness set before us, we shall not think it strange that so much stress is laid upon this. The regenerating work of the Holy Spirit is compared to water. It is also probable that Christ had reference to the ordinance of baptism. Not that all those, and those only, that are baptized, are saved; but without that new birth which is wrought by the Spirit, and signified by baptism, none shall be subjects of the kingdom of heaven. The same word signifies both the wind and the Spirit. The wind bloweth where it listeth for us; God directs it. The Spirit sends his influences where, and when, on whom, and in what measure and degree, he pleases. Though the causes are hidden, the effects are plain, when the soul is brought to mourn for sin, and to breathe after Christ. Christ's stating of the doctrine and the necessity of regeneration, it should seem, made it not clearer to Nicodemus. Thus the things of the Spirit of God are foolishness to the natural man. Many think that cannot be proved, which they cannot believe. Christ's discourse of gospel truths, ver. 11-13, shows the folly of those who make these things strange unto them; and it recommends us to search them out. Jesus Christ is every way able to reveal the will of God to us; for he came down from heaven, and yet is in heaven. We have here a notice of Christ's two distinct natures in one person, so that while he is the Son of man, yet he is in heaven. God is the HE THAT IS, and heaven is the dwelling-place of his holiness. The knowledge of this must be from above, and can be received by faith alone. Jesus Christ came to save us by healing us, as the children of Israel, stung with fiery serpents, were cured and lived by looking up to the brazen serpent, Nu 21:6-9. In this observe the deadly and destructive nature of sin. Ask awakened consciences, ask damned sinners, they will tell you, that how charming soever the allurements of sin may be, at the last it bites like a serpent. See the powerful remedy against this fatal malady. Christ is plainly set forth to us in the gospel. He whom we offended is our Peace, and the way of applying for a cure is by believing. If any so far slight either their disease by sin, or the method of cure by Christ, as not to receive Christ upon his own terms, their ruin is upon their own heads. He has said, Look and be saved, look and live; lift up the eyes of your faith to Christ crucified. And until we have grace to do this, we shall not be cured, but still are wounded with the stings of Satan, and in a dying state. Jesus Christ came to save us by pardoning us, that we might not die by the sentence of the law. Here is gospel, good news indeed. Here is God's love in giving his Son for the world. God so loved the world; so really, so richly. Behold and wonder, that the great God should love such a worthless world! Here, also, is the great gospel duty, to believe in Jesus Christ. God having given him to be our Prophet, Priest, and King, we must give up ourselves to be ruled, and taught, and saved by him. And here is the great gospel benefit, that whoever believes in Christ, shall not perish, but shall have everlasting life. God was in Christ reconciling the world to himself, and so saving it. It could not be saved, but through him; there is no salvation in any other. From all this is shown the happiness of true believers; he that believeth in Christ is not condemned. Though he has been a great sinner, yet he is not dealt with according to what his sins deserve. How great is the sin of unbelievers! God sent One to save us, that was dearest to himself; and shall he not be dearest to us? How great is the misery of unbelievers! they are condemned already; which speaks a certain condemnation; a present condemnation. The wrath of God now fastens upon them; and their own hearts condemn them. There is also a condemnation grounded on their former guilt; they are open to the law for all their sins; because they are not by faith interested in the gospel pardon. Unbelief is a sin against the remedy. It springs from the enmity of the heart of man to God, from love of sin in some form. Read also the doom of those that would not know Christ. Sinful works are works of darkness. The wicked world keep as far from this light as they can, lest their deeds should be reproved. Christ is hated, because sin is loved. If they had not hated saving knowledge, they would not sit down contentedly in condemning ignorance. On the other hand, renewed hearts bid this light welcome. A good man acts truly and sincerely in all he does. He desires to know what the will of God is, and to do it, though against his own worldly interest. A change in his whole character and conduct has taken place. The love of God is shed abroad in his heart by the Holy Ghost, and is become the commanding principle of his actions. So long as he continues under a load of unforgiven guilt, there can be little else than slavish fear of God; but when his doubts are done away, when he sees the righteous ground whereon this forgiveness is built, he rests on it as his own, and is united to God by unfeigned love. Our works are good when the will of God is the rule of them, and the glory of God the end of them; when they are done in his strength, and for his sake; to him, and not to men. Regeneration, or the new birth, is a subject to which the world is very averse; it is, however, the grand concern, in comparison with which every thing else is but trifling. What does it signify though we have food to eat in plenty, and variety of raiment to put on, if we are not born again? if after a few mornings and evenings spent in unthinking mirth, carnal pleasure, and riot, we die in our sins, and lie down in sorrow? What does it signify though we are well able to act our parts in life, in every other respect, if at last we hear from the Supreme Judge, Depart from me, I know you not, ye workers of iniquity?If I have told you earthly things - Things which occur on earth. Not sensual or worldly things, for Jesus had said nothing of these; but he had told him of operations of the Spirit which had occurred "on earth," whose effects were visible, and which "might" be, therefore, believed. These were the plainest and most obvious of the doctrines of religion.

How shall ye believe - How will you believe. Is there any probability that you will understand them?

Heavenly things - Things pertaining to the government of God and his doings in the heavens; things which are removed from human view, and which cannot be subjected to human sight; the more profound and inscrutable things pertaining to the redemption of men. Hence, learn:

1. The height and depth of the doctrines of religion. There is much that we cannot yet understand,

2. The feebleness of our understandings and the corruptions of our hearts are the real causes why doctrines of religion are so little understood by us.

3. There is before us a vast eternity, and there are profound wonders of God's government, to be the study of the righteous, and to be seen and admired by them forever and ever.

12. earthly things—such as regeneration, the gate of entrance to the kingdom of God on earth, and which Nicodemus should have understood better, as a truth even of that more earthly economy to which he belonged.

heavenly things—the things of the new and more heavenly evangelical economy, only to be fully understood after the effusion of the Spirit from heaven through the exalted Saviour.

If I have spoken to you plain things, and in a plain style, humbling my phrase to your apprehensions, and illustrating sublime, spiritual mysteries, which in their own nature are more remote from your apprehensions, by plain and obvious similitudes and parables, and speaking thus, you understand and believe not; what would you do if I should discourse to you sublime and spiritual things, without these advantages for your understandings?

If I have told you earthly things,.... Not that the doctrines he delivered were earthly ones; for he was not of the earth, but from heaven, and above all, and so spake not of the earth, but of heaven, John 3:31; and this doctrine of regeneration was an heavenly doctrine; and the thing itself required supernatural power, and grace from above: but either they were the more easy doctrines of the Gospel; or were delivered in a plain and easy style, and illustrated by similes taken from earthly things, as from human birth, from the water, and from the wind:

and ye believe not; i.e. those things; ye do not receive them, nor give credit to them; or "me", as the Ethiopic Version adds, who relate them on the best evidence, having fully known, and clearly seen them:

how shall ye believe; give credit to me, or receive my testimony:

if I tell you of heavenly things? of the more sublime doctrines of the Gospel, such as the descent of the Messiah from heaven; the union of the two natures, human and divine, in him; his being the only begotten Son of God; his crucifixion and death, signified by the lifting up of the serpent on a pole in the wilderness; and the wonderful love of God to the Gentile world in giving Christ to, and for them; and the salvation, and eternal happiness of all that believe in him, whether they be Jews or Gentiles; and these delivered in language suitable to them, without figures, or natural similes, which help the understanding, and convey ideas of things more easily to it.

If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
