Whosoever is born of God doth not commit sin - This passage must either mean that they who are born of God, that is, who are true Christians, do not sin habitually and characteristically, or that everyone who is a true Christian is absolutely perfect, and never commits any sin. If it can be used as referring to the doctrine of absolute perfection at all, it proves, not that Christians may be perfect, or that a "portion" of them are, but that all are. But who can maintain this? Who can believe that John meant to affirm this? Nothing can be clearer than that the passage has not this meaning, and that John did not teach a doctrine so contrary to the current strain of the Scriptures, and to fact; and if he did not teach this, then in this whole passage he refers to those who are habitually and characteristically righteous.
For his seed remaineth in him - There is much obscurity in this expression, though the general sense is clear, which is, that there is something abiding in the heart of the true Christian which the apostle here calls "seed," which will prevent his sinning. The word "his" in this phrase, "his seed," may refer either to the individual himself - in the sense that this can now be properly called "his," inasmuch as it is a part of himself, or a principle abiding in him; or it may refer to God - in the sense that what is here called "seed" is "his," that is, he has implanted it, or it is a germ of divine origin. Robinson (Lex.) understands it in the latter sense, and so also do Macknight, Doddridge, Lucke, and others, and this is probably the true interpretation. The word "seed" (σπέρμα sperma) means properly seed sown, as of grain, plants, trees; then anything that resembles it, anything which germinates, or which springs up, or is produced.
It is applied in the New Testament to the word of God, or the gospel, as that which produces effects in the heart and life similar to what seed that is sown does. Compare Matthew 13:26, Matthew 13:37-38. Augustin, Clemens, (Alex.,) Grotius, Rosenmuller, Benson, and Bloomfield, suppose that this is the signification of the word here. The proper idea, according to this, is that the seed referred to is truth, which God has implanted or sown in the heart, from which it may be expected that the fruits of righteousness will grow. But that which abides in the heart of a Christian is not the naked word of God; the mere gospel, or mere truth; it is rather that word as made vital and efficacious by the influence of his Spirit; the germ of the divine life; the principles of true piety in the soul. Compare the words of Virgil: Igneus est illi vigor et coelestis origo semini. The exact idea here, as it seems to me, is not that the "seed" refers to "the word of God," as Augustin and others suppose, or to "the Spirit of God," but to the germ of piety which has been produced in the heart "by" the word and Spirit of God, and which may be regarded as having been implanted there by God himself, and which may be expected to produce holiness in the life. There is, probably, as Lucke supposes, an allusion in the word to the fact that we are begotten (Ὁ γεγεννημένος Ho gegennēmenos of God. The word "remaineth" - μένει menei, compare the notes at 1-John 3:6 - is a favorite expression of John. The expression here used by John, thus explained, would seem to imply two things:
(1) that the germ or seed of religion implanted in the soul abides there as a constant, vital principle, so that he who is born of God cannot become habitually a sinner; and,
(2) that it will so continue to live there that he will not fall away and perish. The idea is clearly that the germ or principle of piety so permanently abides in the soul, that he who is renewed never can become again characteristically a sinner.
And he cannot sin - Not merely he will not, but he cannot; that is, in the sense referred to. This cannot mean that one who is renewed has not physical ability to do wrong, for every moral agent has; nor can it mean that no one who is a true Christian never does, in fact, do wrong in thought, word, or deed, for no one could seriously maintain that: but it must mean that there is somehow a certainty as absolute "as if" it were physically impossible, that those who are born of God will not be characteristically and habitually sinners; that they will not sin in such a sense as to lose all true religion and be numbered with transgressors; that they will not fall away and perish. Unless this passage teaches that no one who is renewed ever can sin in any sense; or that everyone who becomes a Christian is, and must be, absolutely and always perfect, no words could more clearly prove that true Christians will never fall from grace and perish. How can what the apostle here says be true, if a real Christian can fall away and become again a sinner?
Because he is born of God - Or begotten of God. God has given him, by the new birth, real, spiritual life, and that life can never become extinct.

Whosoever is born of God - Γεγεννημενος, Begotten of God, doth not commit sin: "that is," say some, "as he used to do, he does not sin habitually as he formerly did." This is bringing the influence and privileges of the heavenly birth very low indeed. We have the most indubitable evidence that many of the heathen philosophers had acquired, by mental discipline and cultivation, an entire ascendency over all their wonted vicious habits. Perhaps my reader will recollect the story of the physiognomist, who, coming into the place where Socrates was delivering a lecture, his pupils, wishing to put the principles of the man's science to proof, desired him to examine the face of their master, and say what his moral character was. After a full contemplation of the philosopher's visage, he pronounced him "the most gluttonous, drunken, brutal, and libidinous old man that he had ever met." As the character of Socrates was the reverse of all this, his disciples began to insult the physiognomist. Socrates interfered, and said, "The principles of his science may he very correct, for such I was, but I have conquered it by my philosophy." O ye Christian divines! ye real or pretended Gospel ministers! will ye allow the influence of the grace of Christ a sway not even so extensive as that of the philosophy of a heathen who never heard of the true God?

Whosoever is born of God doth not commit sin; for his (m) seed remaineth in him: and he cannot sin, because he is born of God.
(m) The Holy Spirit is so called by the effect he works, because by his power and mighty working, as it were by seed, we are made new men.

Whosoever is born of God,.... In a figurative and spiritual sense; who are regenerated, or born from above; who are quickened by the grace of God, and have Christ formed in them; who are made partakers of the divine nature, and new creatures in Christ; which spiritual birth is not owing to men, to the power and will of men, but to the grace of God; and is sometimes ascribed to the Father, who of his own will and abundant mercy begets souls again to a lively hope, and saves them by the washing of regeneration; and sometimes to Christ, who quickens whom he will, whose grace is implanted, and image stamped in it, and by whose resurrection from the dead men are begotten again; and chiefly, to the Spirit of God, who is the author of regeneration, and of the whole of sanctification: and such as are born of him are alive through him, the spirit of life entering into them, and live to God and upon Christ, and breathe after divine and spiritual things, and have their senses to discern them; they see, hear, feel, taste, and savour them; and desire the sincere milk of the word, for their nourishment and growth; and have every grace implanted in them, as faith, hope, and love: and of every such an one it is said, he
doth not commit sin; does not make it his trade and business; it is not the constant course of his life; he does not live and walk in sin, or give up himself to it; he is not without the being of it in him, or free from acts of sin in his life and conversation, but he does not so commit it as to be the servant of it, a slave unto it, or to continue in it; and that for this reason:
for his seed remaineth in him; not the word of God, or the Gospel, though that is a seed which is sown by the ministers of it, and blessed by God, and by which he regenerates his people; and which having a place in their hearts, becomes the ingrafted word, and there abides, nor can it be rooted out; where it powerfully teaches to avoid sin, is an antidote against it, and a preservative from it: nor the Holy Spirit of God, though he is the author of the new birth, and the principle of all grace; and where he once is, he always abides; and through the power of his grace believers prevail against sin, and mortify the deeds of the body, and live: but rather the grace of the Spirit, the internal principle of grace in the soul, the new nature, or new man formed in the soul, is meant; which seminally contains all grace in it, and which, like seed, springs up and gradually increases, and always abides; and is pure and incorruptible, and neither sins itself, nor encourages sin, but opposes, checks, and prevents it:
and he cannot sin; not that it is impossible for such a man to do acts of sin, or that it is possible for him to live without sin; for the words are not to be understood in the sense of those who plead for perfection in this life; for though the saints have perfection in Christ, yet not in themselves; they are not impeccable, they are not free from sin, neither from the being nor actings of it; sin is in them, lives in them, dwells in them, hinders all the good, and does all the mischief it can: or in such sense, as if the sins of believers were not sins; for though they are pardoned and expiated, and they are justified from them, yet they do not cease to be sins; they are equally contrary to the nature, will, and law of God, as well as the sins of others; and are oftentimes attended with more aggravated circumstances, and which God in a fatherly way takes notice of, and chastises for, and on the account of which he hides his face from them: nor does the phrase intend any particular single sin, which cannot be committed; though there are such, as sinning wilfully after receiving the knowledge of the truth, or denying Christ to be the Saviour of sinners, and a sacrifice for sin, and hatred of a Christian brother as such, and sinning the sin unto death, or the unpardonable sin; neither of which can be committed by a regenerate man: nor is the meaning only, though it is a sense that will very well bear, and agrees with the context, that such persons cannot sin as unregenerate men do; that is, live in a continued course of sinning, and with pleasure, and without reluctance, and so as to lie in it, as the whole world does: but rather the meaning is, he that is born of God, as he is born of God, or that which is born of God in him, the new man, or new creature, cannot sin; for that is pure and holy; there is nothing sinful in it, nor can anything that is sinful come out of it, or be done by it; it is the workmanship of the Holy Spirit of God; it is a good work, and well pleasing: in the sight of God, who is of purer eyes than to behold sin with delight; and an incorruptible seed, which neither corrupts nor is corrupted; and though it is as yet an imperfect work, it is not impure: the reason of the impeccability of the regenerate man, as such, is
because he is born of God: for that which is born of God in him, does, under the influence of the Spirit, power, and grace of God, preserve him from the temptations of Satan, the pollutions of the world, and the corruptions of his own heart; see 1-John 5:18; which the Vulgate Latin version there renders, "the generation of God", meaning regeneration, or that which is born of God, "preserveth him": this furnishes out a considerable argument for the perseverance of the saints.

Whosoever is born of God--literally, "Everyone that is begotten of God."
doth not commit sin--His higher nature, as one born or begotten of God, doth not sin. To be begotten of God and to sin, are states mutually excluding one another. In so far as one sins, he makes it doubtful whether he be born of God.
his seed--the living word of God, made by the Holy Spirit the seed in us of a new life and the continual mean of sanctification.
remaineth--abideth in him (compare Note, see on 1-John 3:6; John 5:38). This does not contradict 1-John 1:8-9; the regenerate show the utter incompatibility of sin with regeneration, by cleansing away every sin into which they may be betrayed by the old nature, at once in the blood of Christ.
cannot sin, because he is born of God--"because it is of God that he is born" (so the Greek order, as compared with the order of the same words in the beginning of the verse); not "because he was born of God" (the Greek is perfect tense, which is present in meaning, not aorist); it is not said, Because a man was once for all born of God he never afterwards can sin; but, Because he is born of God, the seed abiding now in Him, he cannot sin; so long as it energetically abides, sin can have no place. Compare Genesis 39:9, Joseph, "How CAN I do this great wickedness and sin against God?" The principle within me is at utter variance with it. The regenerate life is incompatible with sin, and gives the believer a hatred for sin in every shape, and an unceasing desire to resist it. "The child of God in this conflict receives indeed wounds daily, but never throws away his arms or makes peace with his deadly foe" [LUTHER]. The exceptional sins into which the regenerate are surprised, are owing to the new life principle being for a time suffered to lie dormant, and to the sword of the Spirit not being drawn instantly. Sin is ever active, but no longer reigns. The normal direction of the believer's energies is against sin; the law of God after the inward man is the ruling principle of his true self though the old nature, not yet fully deadened, rebels and sins. Contrast 1-John 5:18 with John 8:34; compare Psalm 18:22-23; Psalm 32:2-3; Psalm 119:113, Psalm 119:176. The magnetic needle, the nature of which is always to point to the pole, is easily turned aside, but always reseeks the pole.

Whosoever is born of God - By living faith, whereby God is continually breathing spiritual life into his soul, and his soul is continually breathing out love and prayer to God, doth not commit sin. For the divine seed of loving faith abideth in him; and, so long as it doth, he cannot sin, because he is born of God - Is inwardly and universally changed.
