The apostle, having shown the dignity of Christ's faithful followers, that they are born of him and thereby nearly allied to God, now here, I. Breaks forth into the admiration of that grace that is the spring of such a wonderful vouchsafement: Behold (see you, observe) what manner of love, or how great love, the Father hath bestowed upon us, that we should be called, effectually called (he who calls things that are not makes them to be what they were not) the sons of God! The Father adopts all the children of the Son. The Son indeed calls them, and makes them his brethren; and thereby he confers upon them the power and dignity of the sons of God. It is wonderful condescending love of the eternal Father, that such as we should be made and called his sons - we who by nature are heirs of sin, and guilt, and the curse of God - we who by practice are children of corruption, disobedience, and ingratitude! Strange, that the holy God is not ashamed to be called our Father, and to call us his sons! Thence the apostle, II. Infers the honour of believers above the cognizance of the world. Unbelievers know little of them. Therefore (or wherefore, upon this score) the world knoweth us not, Jo1 3:1. Little does the world perceive the advancement and happiness of the genuine followers of Christ. They are here exposed to the common calamities of earth and time; all things fall alike to them as to others, or rather they are subject to the greater sorrow, for they have often reason to say, If in this life only we have hope in Christ, we are of all men most miserable, Co1 15:19. The unchristian world, therefore, that walks by sight, knows not their dignity, their privileges, the enjoyments they have in hand, nor what they are entitled to. Little does the world think that these poor, humble, contemned ones are the favourites of heaven, and will be inhabitants there ere long. And they may bear their case the better since their Lord was here unknown as well as they: Because it knew him not, Jo1 3:1. Little did the world think how great a person was once sojourning here, that the Maker of it was once an inhabitant of it. Little did the Jewish world think that the God of Abraham, Isaac, and Jacob, was one of their blood, and dwelt in their land; he came to his own, and his own received him not. He came to his own, and his own crucified him; but surely, had they known him, they would not have crucified the Lord of glory, Co1 2:8. Let the followers of Christ be content with hard fare here, since they are in a land of strangers, among those who little know them, and their Lord was so treated before them. Then the apostle, III. Exalts these persevering disciples in the prospect of the certain revelation of their state and dignity. Here, 1. Their present honourable relation is asserted: Beloved (you may well be our beloved, for you are beloved of God), now are we the sons of God, Jo1 3:2. We have the nature of sons by regeneration: we have the title, and spirit, and right to the inheritance of sons by adoption. This honour have all the saints. 2. The discovery of the bliss belonging and suitable to this relation is denied: And it doth not yet appear what we shall be, Jo1 3:2. The glory pertaining to the sonship and adoption is adjourned and reserved for another world. The discovery of it here would put a stop to the current of affairs that must now proceed. The sons of God must walk by faith, and live by hope. 3. The time of the revelation of the sons of God in their proper state and glory is determined; and that is when their elder brother comes to call and collect them all together: But we know that when he shall appear we shall be like him. The particle, ean, usually translated if, is here well rendered when; for the Hebrew particle am (to which this is thought to correspond) is observed so to signify, as Dr. Whitby has here noted; and not only is ean sometimes used for hotan, but some copies even here read hotan, when. And accordingly it seems proper so to render it in Joh 14:3, where we read it, And if I go, and prepare a place; but more naturally and properly, When I shall have gone, and shall have prepared the place, I will come again, and receive you unto myself, or paralēpsomai - I will take you along with myself, that where I am there you may be also. When the head of the church, the only-begotten of the Father, shall appear, his members, the adopted of God, shall appear and be manifested together with him. They may then well wait in faith, hope, and earnest desire, for the revelation of the Lord Jesus; as even the creation itself waiteth for their perfection, and the public manifestation of the sons of God, Rom 8:19. The sons of God will be known and be made manifest by their likeness to their head: They shall be like him - like him in honour, and power, and glory. Their vile bodies shall be made like his glorious body; they shall be filled with life, light, and bliss from him. When he, who is their life, shall appear, they also shall appear with him in glory, Col 3:4. Then, 4. Their likeness to him is argued from the sight they shall have of him: We shall be like him, for we shall see him as he is. Their likeness will be the cause of that sight which they shall have of him. Indeed, all shall see him, but not as they do; not as he is, namely, to those in heaven. The wicked shall see him in his frowns, in the terror of his majesty, and the splendour of his avenging perfections; but these shall see him in the smiles and beauty of his face, in the correspondence and amiableness of his glory, in the harmony and agreeableness of his beatific perfections. Their likeness shall enable them to see him as the blessed do in heaven. Or the sight of him shall be the cause of their likeness; it shall be a transformative sight: they shall be transformed into the same image by the beatific view that they shall have of him. Then the apostle, IV. Urges the engagement of these sons of God to the prosecution of holiness: And every man that hath this hope in him purifies himself even as he is pure, Jo1 3:3. The sons of God know that their Lord is holy and pure; he is of purer heart and eyes than to admit any pollution or impurity to dwell with him. Those then who hope to live with him must study the utmost purity from the world, and flesh, and sin; they must grow in grace and holiness. Not only does their Lord command them to do so, but their new nature inclines them so to do; yea, their hope of heaven will dictate and constrain them so to do. They know that their high priest is holy, harmless, and undefiled. They know that their Go and Father is the high and holy one, that all the society is pure and holy, that their inheritance is an inheritance of saints in light. It is a contradiction to such hope to indulge sin and impurity. And therefore, as we are sanctified by faith, we must be sanctified by hope. That we may be saved by hope we must be purified by hope. It is the hope of hypocrites, and not of the sons of God, that makes an allowance for the gratification of impure desires and lusts.

The apostle, having alleged the believer's obligation to purity from his hope of heaven, and of communion with Christ in glory at the day of his appearance, now proceeds to fill his own mouth and the believer's mind with multiplied arguments against sin, and all communion with the impure unfruitful works of darkness. And so he reasons and argues, I. From the nature of sin and the intrinsic evil of it. It is a contrariety to the divine law: Whosoever committeth sin transgresseth also (or even) the law (or, whosoever committeth sin even committeth enormity, or aberration from law, or from the law); for sin is the transgression of the law, or is lawlessness, Jo1 3:4. Sin is the destitution or privation of correspondence and agreement with the divine law, that law which is the transcript of the divine nature and purity, which contains his will for the government of the world, which is suitable to the rational nature, and enacted for the good of the world, which shows man the way of felicity and peace, and conducts him to the author of his nature and of the law. The current commission of sin now is the rejection of the divine law, and this is the rejection of the divine authority, and consequently of God himself. II. From the design and errand of the Lord Jesus in and to this world, which was to remove sin: And you know that he was manifested to take away our sins, and in him is no sin, Jo1 3:5. The Son of God appeared, and was known, in our nature; and he came to vindicate and exalt the divine law, and that by obedience to the precept, and by subjection and suffering under the penal sanction, under the curse of it. He came therefore to take away our sins, to take away the guilt of them by the sacrifice of himself, to take away the commission of them by implanting a new nature in us (for we are sanctifies by virtue of his death), and to dissuade and save from it by his own example, and (or for) in him was no sin; or, he takes sin away, that he may conform us to himself, and in him is no sin. Those that expect communion with Christ above should study communion with him here in the utmost purity. And the Christian world should know and consider the great end of the Son of God's coming hither: it was to take away our sin: And you know (and this knowledge should be deep and effectual) that he was manifested to take away our sins. III. From the opposition between sin and a real union with or adhesion to the Lord Christ: Whosoever abideth in him sinneth not, Jo1 3:6. To sin here is the same as to commit sin (Jo1 3:8, Jo1 3:9), and to commit sin is to practise sin. He that abideth in Christ continues not in the practice of sin. As vital union with the Lord Jesus broke the power of sin in the heart and nature, so continuance therein prevents the regency and prevalence thereof in the life and conduct. Or the negative expression here is put for the positive: He sinneth not, that is, he is obedient, he keeps the commandments (in sincerity, and in the ordinary course of life) and does those things that are pleasing in his sight, as is said Jo1 3:22. Those that abide in Christ abide in their covenant with him, and consequently watch against the sin that is contrary thereto. They abide in the potent light and knowledge of him; and therefore it may be concluded that he that sinneth (abideth in the predominant practice of sin) hath not seen him (hath not his mind impressed with a sound evangelical discerning of him), neither known him, hath no experimental acquaintance with him. Practical renunciation of sin is the great evidence of spiritual union with, continuance in, and saving knowledge of, the Lord Christ. IV. From the connection between the practice of righteousness and a state of righteousness, intimating withal that the practice of sin and a justified state are inconsistent; and this is introduced with a supposition that a surmise to the contrary is a gross deceit: "Little children, dear children, and as much children as you are, herein let no man deceive you. There will be those who will magnify your new light and entertainment of Christianity, who will make you believe that your knowledge, profession, and baptism, will excuse you from the care and accuracy of the Christian life. But beware of such self-deceit. He that doeth righteousness in righteous." It may appear that righteousness may in several places of scripture be justly rendered religion, as Mat 5:10, Blessed are those that are persecuted for righteousness' sake, that is, for religion's sake; Pe1 3:14, But if you suffer for righteousness' sake (religion's sake) happy are you; and Ti2 3:16, All scripture, or the whole scripture, is given by inspiration of God, and is profitable for doctrine - and for instruction in righteousness, that is, in the nature and branches of religion. To do righteousness then, especially being set in opposition to the doing, committing, or practising, of sin, is to practise religion. Now he who practiseth religion is righteous; he is the righteous person on all accounts; he is sincere and upright before God. The practice of religion cannot subsist without a principle of integrity and conscience. He has that righteousness which consists in pardon of sin and right to life, founded upon the imputation of the Mediator's righteousness. He has a title to the crown of righteousness, which the righteous Judge will give, according to his covenant and promise, to those that love his appearing, Ti2 4:8. He has communion with Christ, in conformity to the divine law, being in some measure practically righteous as he; and he has communion with him in the justified state, being now relatively righteous together with him. V. From the relation between the sinner and the devil, and thereupon from the design and office of the Lord Christ against the devil. 1. From the relation between the sinner and the devil. As elsewhere sinners and saints are distinguished (though even saints are sinners largely so called), so to commit sin is here so to practise it as sinners do, that are distinguished from saints, to live under the power and dominion of it; and he who does so is of the devil; his sinful nature is inspired by, and agreeable and pleasing to, the devil; and he belongs to the party, and interest, and kingdom of the devil. It is he that is the author and patron of sin, and has been a practitioner of it, a tempter and instigator to it, even from the beginning of the world. And thereupon we must see how he argues. 2. From the design and office of the Lord Christ against the devil: For this purpose the Son of God was manifested, that he might destroy the works of the devil, Jo1 3:8. The devil has designed and endeavoured to ruin the work of God in this world. The Son of God has undertaken the holy war against him. He came into our world, and was manifested in our flesh, that he might conquer him and dissolve his works. Sin will he loosen and dissolve more and more, till he has quite destroyed it. Let not us serve or indulge what the Son of God came to destroy. VI. From the connection between regeneration and the relinquishment of sin: Whosoever is born of God doth not commit sin. To be born of God is to be inwardly renewed, and restored to a holy integrity or rectitude of nature by the power of the Spirit of God. Such a one committeth not sin, does not work iniquity nor practise disobedience, which is contrary to his new nature and the regenerate complexion of his spirit; for, as the apostle adds, his seed remaineth in him, either the word of God in its light and power remaineth in him (as Pe1 1:23, Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever), or, that which is born of the Spirit is spirit; the spiritual seminal principle of holiness remaineth in him. Renewing grace is an abiding principle. Religion, in the spring of it, is not an art, an acquired dexterity and skill, but a new nature. And thereupon the consequence is the regenerate person cannot sin. That he cannot commit an act of sin, I suppose no judicious interpreter understands. This would be contrary to Jo1 1:9, where it is made our duty to confess our sins, and supposed that our privilege thereupon is to have our sins forgiven. He therefore cannot sin, in the sense in which the apostle says, he cannot commit sin. He cannot continue in the course and practice of sin. He cannot so sin as to denominate him a sinner in opposition to a saint or servant of God. Again, he cannot sin comparatively, as he did before he was born of God, and as others do that are not so. And the reason is because he is born of God, which will amount to all this inhibition and impediment. 1. There is a light in his mind which shows him the evil and malignity of sin. 2. There is that bias upon his heart which disposes him to loathe and hate sin. 3. There is the spiritual seminal principle or disposition, that breaks the force and fulness of the sinful acts. They proceed not from such plenary power of corruption as they do in others, nor obtain that plenitude of heart, spirit, and consent, which they do in others. The spirit lusteth against the flesh. And therefore in respect to such sin it may be said, It is no more I that do it, but sin that dwelleth in me. It is not reckoned the person's sin, in the gospel account, where the bent and frame of the mind and spirit are against it. Then, 4. There is a disposition for humiliation and repentance for sin, when it has been committed. He that is born of God cannot sin. Here we may call to mind the usual distinction of natural and moral impotency. The unregenerate person is morally unable for what is religiously good. The regenerate person is happily disabled for sin. There is a restraint, an embargo (as we may say), laid upon his sinning powers. It goes against him sedately and deliberately to sin. We usually say of a person of known integrity, "He cannot lie, he cannot cheat, and commit other enormities." How can I commit this great wickedness, and sin against God! Gen 39:9. And so those who persist in a sinful life sufficiently demonstrate that they are not born of God. VII. From the discrimination between the children of God and the children of the devil. They have their distinct characters. In this the children of God are manifest and the children of the devil, Jo1 3:10. In the world (according to the old distinction) there are the seed of God and the seed of the serpent. Now the seed of the serpent is known by these two signatures: - 1. By neglect of religion: Whosoever doeth not righteously (omits and disregards the rights and dues of God; for religion is but our righteousness towards God, or giving him his due, and whosoever does not conscientiously do this) is not of God, but, on the contrary, of the devil. The devil is the father of unrighteous or irreligious souls. And, 2. By hatred of fellow-christians: Neither he that loveth not his brother, Jo1 3:10. True Christians are to be loved for God's and Christ's sake. Those who so love them not, but despise, and hate, and persecute them, have the serpentine nature still abiding in them.
