Verily, verily, I say to thee. The word Verily (amen) is twice repeated, and this is done for the purpose of arousing him to more earnest attention. For when he was about to speak of the most important and weighty of all subjects, he found it necessary to awaken the attention of Nicodemus, who might otherwise have passed by this whole discourse in a light or careless manner. [1] Such, then, is the design of the double affirmation. Though this discourse appears to be far-fetched and almost inappropriate, yet it was with the utmost propriety that Christ opened his discourse in this manner. For as it is useless to sow seed in a field which has not been prepared by the labors of the husbandman, so it is to no purpose to scatter the doctrine of the Gospel, if the mind has not been previously subdued and duly prepared for docility and obedience. Christ saw that the mind of Nicodemus was filled with many thorns, choked by many noxious herbs, so that there was scarcely any room for spiritual doctrine. This exhortation, therefore, resembled a ploughing to purify him, that nothing might prevent him from profiting by the doctrine. Let us, therefore, remember that this was spoken to one individual, in such a manner that the Son of God addresses all of us daily in the same language. For which of us will say that he is so free from sinful affections that he does not need such a purification? If, therefore, we wish to make good and useful progress in the school of Christ, let us learn to begin at this point. Unless a man be born again. That is, So long as thou art destitute of that which is of the highest importance in the kingdom of God, I care little about your calling me Master; for the first entrance into the kingdom of God is, to become a new man. But as this is a remarkable passage, it will be proper to survey every part of it minutely. To SEE the kingdom of God is of the same meaning as to enter into the kingdom of God, as we shall immediately perceive from the context. But they are mistaken who suppose that the kingdom of God means Heaven; for it rather means the spiritual life, which is begun by faith in this world, and gradually increases every day according to the continued progress of faith. So the meaning is, that no man can be truly united to the Church, so as to be reckoned among the children of God, until he has been previously renewed. This expression shows briefly what is the beginning of Christianity, and at the same time teaches us, that we are born exiles and utterly alienated from the kingdom of God, and that there is a perpetual state of variance between God and us, until he makes us altogether different by our being born again; for the statement is general, and comprehends the whole human race. If Christ had said to one person, or to a few individuals, that they could not enter into heaven, unless they had been previously born again, we might have supposed that it was only certain characters that were pointed out, but he speaks of all without exception; for the language is unlimited, and is of the same import with such universal terms as these: Whosoever shall not be born again cannot enter into the kingdom of God By the phrase born again is expressed not the correction of one part, but the renovation of the whole nature. Hence it follows, that there is nothing in us that is not sinful; for if reformation is necessary in the whole and in each part, corruption must have been spread throughout. On this point we shall soon have occasion to speak more largely. Erasmus, adopting the opinion of Cyril, has improperly translated the adverb anothen, from above, and renders the clause thus: unless a man be born from above. The Greek word, I own, is ambiguous; but we know that Christ conversed with Nicodemus in the Hebrew language. There would then have been no room for the ambiguity which occasioned the mistake of Nicodemus and led him into childish scruples about a second birth of the flesh. He therefore understood Christ to have said nothing else than that a man must be born again, before he is admitted into the kingdom of God.

Footnotes

1 - "L'oyant seulement comme en pensant ailleurs, et sans en tenir grand conte:" -- "merely listening to it as if he were thinking of something else, and without caring much about it."

Verily, verily - An expression of strong affirmation, denoting the certainty and the importance of what he was about to say. Jesus proceeds to state one of the fundamental and indispensable doctrines of his religion. It may seem remarkable that he should introduce this subject in this manner; but it should be remembered that Nicodemus acknowledged that he was a teacher come from God; that he implied by that his readiness and desire to receive instruction; and that it is not wonderful, therefore, that Jesus should commence with one of the fundamental truths of his religion. It is no part of Christianity to conceal anything. Jesus declared to every man, high or low, rich or poor, the most humbling truths of the gospel. Nothing was kept back for fear of offending men of wealth or power; and for them, as well as the most poor and lowly, it was declared to be indispensable to experience, as the first thing in religion, a change of heart and of life.
Except a man - This is a universal form of expression designed to include all mankind. Of "each and every man" it is certain that unless he is born again he cannot see the kingdom of God. It includes, therefore, men of every character and rank, and nation, moral and immoral, rich and poor, in office and out of office, old and young, bond and free, the slave and his master, Jew and Gentile. It is clear that our Saviour intended to convey to Nicodemus the idea, also, that "he" must be born again. It was not sufficient to be a Jew, or to acknowledge him to be a teacher sent by God that is, the Messiah; it was necessary, in addition to this, to experience in his own soul that great change called the "new birth" or regeneration.
Be born again - The word translated here "again" means also "from above," and is so rendered in the margin. It is evident, however, that Nicodemus understood, it not as referring to a birth "from above," for if he had he would not have asked the question in John 3:4. It is probable that in the language which he used there was not the same ambiguity that there is in the Greek. The ancient versions all understood it as meaning "again," or the "second time." Our natural birth introduces us to light, is the commencement of life, throws us amid the works of God, and is the beginning of our existence; but it also introduces us to a world of sin. We early go astray. All men transgress. The imagination of the thoughts of the heart is evil from the youth up. We are conceived in sin and brought forth in iniquity, and there is none that doeth good, no, not one. The carnal mind is enmity against God, and by nature we are dead in trespasses and sins, Genesis 8:21; Psalm 14:2-3; Psalm 51:5; Romans 1:29-32; Romans 3:10-20; Romans 8:7.
All sin exposes men to misery here and hereafter. To escape from sin, to be happy in the world to come, it is necessary that man should be changed in his principles, his feelings, and his manner of life. This change, or the beginning of this new life, is called the "new birth," or "regeneration." It is so called because in many respects it has a striking analogy to the natural birth. It is the beginning of spiritual life. It introduces us to the light of the gospel. It is the moment when we really begin to live to any purpose. It is the moment when God reveals himself to us as our reconciled Father, and we are adopted into his family as his sons. And as every man is a sinner, it is necessary that each one should experience this change, or he cannot be happy or saved. This doctrine was not unknown to the Jews, and was particularly predicted as a doctrine that would be taught in the times of the Messiah. See Deuteronomy 10:16; Jeremiah 4:4; Jeremiah 31:33; Ezekiel 11:19; Ezekiel 36:25; Psalm 51:12. The change in the New Testament is elsewhere called the "new creation" 2-Corinthians 5:17; Galatians 6:15, and "life from the dead," or a resurrection, Ephesians 2:1; John 5:21, John 5:24.
He cannot see - To "see," here, is put evidently for enjoying - or he cannot be fitted for it and partake of it.
The kingdom of God - Either in this world or in that which is to come - that is, heaven. See the notes at Matthew 3:2. The meaning is, that the kingdom which Jesus was about to set up was so pure and holy that it was indispensable that every man should experience this change, or he could not partake of its blessings. This is solemnly declared by the Son of God by an affirmation equivalent to an oath, and there can be no possibility, therefore, of entering heaven without experiencing the change which the Saviour contemplated by the "new birth." And it becomes every man, as in the presence of a holy God before whom he must soon appear, to ask himself whether he has experienced this change, and if he has not, to give no rest to his eyes until he has sought the mercy of God, and implored the aid of his Spirit that his heart may be renewed.

Jesus answered - Not in the language of compliment: - he saw the state of Nicodemus's soul, and he immediately addressed himself to him on a subject the most interesting and important. But what connection is there between our Lord's reply, and the address of Nicodemus? Probably our Lord saw that the object of his visit was to inquire about the Messiah's kingdom; and in reference to this he immediately says, Except a man be born again, etc.
The repetition of amen, or verily, verily, among the Jewish writers, was considered of equal import with the most solemn oath.
Be born again - Or, from above: different to that new birth which the Jews supposed every baptized proselyte enjoyed; for they held that the Gentile, who became a proselyte, was like a child new born. This birth was of water from below: the birth for which Christ contends is ανωθεν, from above - by the agency of the Holy Spirit. Every man must have two births, one from heaven, the other from earth - one of his body, the other of his soul: without the first he cannot see nor enjoy this world, without the last he can not see nor enjoy the kingdom of God. As there is an absolute necessity that a child should be born into the world, that he may see its light, contemplate its glories, and enjoy its good, so there is an absolute necessity that the soul should be brought out of its state of darkness and sin, through the light and power of the grace of Christ, that it may be able to see, ιδειν, or, to discern, the glories and excellencies of the kingdom of Christ here, and be prepared for the enjoyment of the kingdom of glory hereafter. The Jews had some general notion of the new birth; but, like many among Christians, they put the acts of proselytism, baptism, etc., in the place of the Holy Spirit and his influence: they acknowledged that a man must be born again; but they made that new birth to consist in profession, confession, and external washing. See on John 3:10 (note).
The new birth which is here spoken of comprehends, not only what is termed justification or pardon, but also sanctification or holiness. Sin must be pardoned, and the impurity of the heart washed away, before any soul can possibly enter into the kingdom of God. As this new birth implies the renewing of the whole soul in righteousness and true holiness, it is not a matter that may be dispensed with: heaven is a place of holiness, and nothing but what is like itself can ever enter into it.

(2) Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot (d) see the (e) kingdom of God.
(2) The beginning of Christianity consists in this, that we know ourselves not only to be corrupt in part, but to be wholly dead in sin: so that our nature has need to be created anew, with regard to its qualities, which can be done by no other power, but by the divine and heavenly, by which we were first created.
(d) That is, "go in", or "enter", as he expounds himself below in (John 3:5).
(e) The Church: for Christ shows here how we come to be citizens and to have anything to do in the city of God.

Jesus answered and said unto him,.... Not to any express question put by Nicodemus; unless it can be thought, that a question of this kind might be asked, what is the kingdom of God, so much spoken of in thy ministry? and what is requisite to the seeing and enjoying of it? though not recorded by the evangelist; but rather to the words of Nicodemus, concluding from his miracles, that he was the Messiah; and that the kingdom of God was now approaching, or the world to come, the Jews so much speak of; and in which all Israel, according to their notion, were to have a part (o); and which notion, our Lord in the following words, seems to oppose:
verily, verily, I say unto thee, except a man be born again, he cannot see the kingdom of God; Nicodemus, according to the general sense of the nation, thought that when the Messiah came, and his kingdom was set up, they should all share in it, without any more ado; they being the descendants of Abraham, and having him for their father: but Christ assures him, that he must be "born again"; in distinction from, and opposition to his first birth by nature; in which he was vile, polluted, carnal, and corrupt, being conceived in sin, and shapen in iniquity, and was a transgressor from the womb, and by nature a child of wrath; and in opposition to, his descent from Abraham, or being born of him, and of his seed; for this would be of no avail to him in this case, nor give him any right to the privileges and ordinances of the kingdom of God, or the Gospel dispensation; see Matthew 3:9; as also to birth by proselytism; for the Jews have a frequent saying (p), that
"one that is made a proselyte, , "is like a child new born".''
Which they understand, not in a spiritual, but in a civil sense; such being free from all natural and civil relations, and from all obligations to parents, masters (q), &c. And by this phrase our Lord signifies, that no man, either as a man, or as a son of Abraham, or as a proselyte to the Jewish religion, can have any true knowledge of, or right unto, the enjoyment of the kingdom of God, unless he is born again; or regenerated, and quickened by the Spirit of God; renewed in the spirit of his mind; has Christ formed in his heart; becomes a partaker of the divine nature; and in all respects a new creature; and an other in heart, in principle, in practice, and conversation; or unless he be "born from above", as the word is rendered in John 3:31; that is, by a supernatural power, having the heavenly image stamped on him; and being called with an heavenly calling, even with the high calling of God in Christ Jesus: if this is not the case, a man can have no true knowledge of the kingdom of the Messiah, which is not a temporal and carnal one; it is not of this world, nor does it come with observation; nor can he have any right to the ordinances of it, which are of a spiritual nature; and much less can he be thought to have any true notions, or to be possessed of the kingdom of grace, which lies in righteousness, peace, and joy in the Holy Ghost; or to have either a meetness for, or a right unto the kingdom of glory: though by the following words it seems, that the word is rightly rendered "again", or a second time, as it is by Nounus.
(o) Misn. Sanhedrin, c. 11. sect. 1. (p) T. Bab. Yebamot, fol. 22. 1. 48. 2. 62. 1. & 97. 2. (q) Vid. Maimon. Issure Bia, c. 14. sect. 11. & Eduth, c. 13. sect. 2.

Except, &c.--This blunt and curt reply was plainly meant to shake the whole edifice of the man's religion, in order to lay a deeper and more enduring foundation. Nicodemus probably thought he had gone a long way, and expected, perhaps, to be complimented on his candor. Instead of this, he is virtually told that he has raised a question which he is not in a capacity to solve, and that before approaching it, his spiritual vision required to be rectified by an entire revolution on his inner man. Had the man been less sincere, this would certainly have repelled him; but with persons in his mixed state of mind--to which Jesus was no stranger (John 2:25) --such methods speed better than more honeyed words and gradual approaches.
a man--not a Jew merely; the necessity is a universal one.
be born again--or, as it were, begin life anew in relation to God; his manner of thinking, feeling, and acting, with reference to spiritual things, undergoing a fundamental and permanent revolution.
cannot see--can have no part in (just as one is said to "see life," "see death," &c.).
the kingdom of God--whether in its beginnings here (Luke 16:16), or its consummation hereafter (Matthew 25:34; Ephesians 5:5).

Verily, verily, I say unto thee. This form of expression was often upon the lips of Jesus to give emphasis to an unusually solemn and weighty declaration. See Matthew 5:18. It occurs twenty-four times in John.
Except a man be born again, he cannot see the kingdom of God. The term translated "again" is rendered "anew" in the Revision, which is better. It is the great doctrine, so fundamental in the Gospel, of Regeneration, a new Birth, being made a new creature, the same doctrine spoken of in John 1:12-13. Nicodemus, like all Jews, supposed that all who were born as children of Abraham would, as Abraham's seed, be citizens of the kingdom, but Jesus shows him that no one can be a new creature in Christ Jesus unless he is born anew. We are born naturally into the kingdom of nature, to live the natural life; if we enter the kingdom of heaven, the kingdom of grace, it must be by a new birth. The doctrine that a man can bury his old sinful life, and begin a new one with the freshness of youthful hope, is foreshadowed in the Old Testament (Isaiah 1:18; Jeremiah 31:33; Ezekiel 11:19; Ezekiel 36:26), and taught in the New Testament (Romans 6:8; Romans 8:3; Romans 12:2; 2-Corinthians 5:17; Galatians 6:15-16).

Jesus answered - That knowledge will not avail thee unless thou be born again - Otherwise thou canst not see, that is, experience and enjoy, either the inward or the glorious kingdom of God. In this solemn discourse our Lord shows, that no external profession, no ceremonial ordinances or privileges of birth, could entitle any to the blessings of the Messiah's kingdom: that an entire change of heart as well as of life was necessary for that purpose: that this could only be wrought in man by the almighty power of God: that every man born into the world was by nature in a state of sin, condemnation, and misery: that the free mercy of God had given his Son to deliver them from it, and to raise them to a blessed immortality: that all mankind, Gentiles as well as Jews, might share in these benefits, procured by his being lifted up on the cross, and to be received by faith in him: but that if they rejected him, their eternal, aggravated condemnation, would be the certain consequence. Except a man be born again - If our Lord by being born again means only reformation of life, instead of making any new discovery, he has only thrown a great deal of obscurity on what was before plain and obvious.
