These verses relate to the concluding subject of the foregoing chapter, in which the apostle proceeds upon the supposition of the real Christian's sin. And here he gives them both dissuasion and support.

1.Dissuasion. He would leave no room for sin: "My little children, these things write I unto you, that you sin not, Jo1 2:1. The design or purport of this letter, the design of what I have just said concerning communion with God and the overthrow of it by an irreligious course, is to dissuade and drive you from sin." See the familiar affectionate compellation with which he introduces his admonition: My little children, children as having perhaps been begotten by his gospel, little children as being much beneath him in age and experience, my little children, as being dear to him in the bonds of the gospel. Certainly the gospel most prevailed where and when such ministerial love most abounded. Or perhaps the judicious reader will find reason to think that the apostle's meaning in this dissuasion or caution is this, or amounts to this reading: These things write I unto you, not that you sin. And so the words will look back to what he had said before concerning the assured pardon of sin: God is faithful and just to forgive us our sins, etc., Jo1 1:9. And so the words are a preclusion of all abuse of such favour and indulgence. "Though sins will be forgiven to penitent confessors, yet this I write, not to encourage you in sin, but upon another account." Or this clause will look forward to what the apostle is going to say about the Advocate for sinners: and so it is a prolepsis, a prevention of like mistake or abuse: "These things write I unto you, not that you sin, but that you may see your remedy for sin." And so the following particle (as the learned know) may be rendered adversatively: But, if a man sin, he may know his help and cure. And so we see,

II.The believer's support and relief in case of sin: And (or but) if any man sin (any of us, or of our foresaid communion), We have we an Advocate with the Father, etc., Jo1 2:1. Believers themselves, those that are advanced to a happy gospel-state, have yet their sins. There is a great distinction therefore between the sinners that are in the world. There are Christianized (such as are instated in the sacred saving privileges of Christ's mystical or spiritual body) and unchristianized, converted and unconverted sinners. There are some who, though they really sin, yet, in comparison with others, are said not to sin, as Jo1 3:9. Believers, as they have an atonement applied unto them at their entrance into a state of pardon and justification, so they have an Advocate in heaven still to continue to them that state, and procure their continued forgiveness. And this must be the support, satisfaction, and refuge of believers (or real Christians) in or upon their sins: We have an Advocate. The original name is sometimes given to the Holy Ghost, and then it is rendered, the Comforter. He acts within us; he puts pleas and arguments into our hearts and mouths; and so is our advocate, by teaching us to intercede for ourselves. But here is an advocate without us, in heaven and with the Father. The proper office and business of an advocate is with the judge; with him he pleads the client's cause. The Judge with whom our advocate pleads is the Father, his Father and ours. He who was our Judge in the legal court (the court of the violated law) is our Father in the gospel court, the court of heaven and of grace. His throne or tribunal is the mercy-seat. And he that is our Father is also our Judge, the supreme arbitrator of our state and circumstances, either for life or death, for time or eternity. You have come - to God, the Judge of all, Heb 12:23. That believers may be encouraged to hope that their cause will go well, as their Judge is represented to them in the relation of a Father, so their advocate is recommended to them upon these considerations: - 1. By his person and personal names. It is Jesus Christ the Son of the Father, one anointed by the Father for the whole office of mediation, the whole work of salvation, and consequently for that of the intercessor or advocate. 2. By his qualification for the office. It is Jesus Christ the righteous, the righteous one in the court and sight of the Judge. This is not so necessary in another advocate. Another advocate (or an advocate in another court) may be an unjust person himself, and yet may have a just cause (and the cause of a just person in that case) to plead, and may accordingly carry his cause. But here the clients are guilty; their innocence and legal righteousness cannot be pleaded; their sin must be confessed or supposed. It is the advocate's own righteousness that he must plead for the criminals. He has been righteous to the death, righteous for them; he has brought in everlasting righteousness. This the Judge will not deny. Upon this score he pleads, that the clients' sins may not be imputed to them. 3. By the plea he has to make, the ground and basis of his advocacy: And he is the propitiation for our sins, Jo1 2:2. He is the expiatory victim, the propitiatory sacrifice that has been offered to the Judge for all our offences against his majesty, and law, and government. In vain do the professors of Rome distinguish between and advocate of redemption and an advocate of intercession, or a mediator of such different service. The Mediator of intercession, the Advocate for us, is the Mediator of redemption, the propitiation for our sins. It is his propitiation that he pleads. And we might be apt to suppose that his blood had lost its value and efficacy if no mention had been made of it in heaven since the time it was shed. But now we see it is of esteem there, since it is continually represented in the intercession of the great advocate (the attorney-general) for the church of God. He ever lives to make intercession for those that come to God through him. 4. By the extent of his plea, the latitude of his propitiation. It is not confined to one nation; and not particularly to the ancient Israel of God: He is the propitiation for our sins; and not for ours only (not only for the sins of us Jews, us that are Abraham's seed according to the flesh), but also for those of the whole world (Jo1 2:2); not only for the past, or us present believers, but for the sins of all who shall hereafter believe on him or come to God through him. The extent and intent of the Mediator's death reach to all tribes, nations, and countries. As he is the only, so he is the universal atonement and propitiation for all that are saved and brought home to God, and to his favour and forgiveness.

My little children - Τεκνια μου· My beloved children; the address of an affectionate father to children whom he tenderly loves. The term also refers to the apostle's authority as their spiritual father, and their obligation to obey as his spiritual children.

That ye sin not - This is the language of the whole Scripture; of every dispensation, ordinance, institution, doctrine, and word of God. Sin not - do not run into ruin; live not so as to promote your own misery; be happy, for it is the will of God that ye should be so; therefore he wills that ye should be holy: holiness and happiness are inseparable; sin and misery are equally so.

And if any man sin - If, through ignorance, inexperience, the violence of temptation, unwatchfulness, etc., ye have fallen into sin, and grieved the Spirit of God, do not continue in the sin, nor under the guilt; do not despair of being again restored to the favor of God; your case, it is true, is deeply deplorable, but not desperate; there is still hope, for -

We have an advocate with the Father - We still have him before the throne who died for our offenses, and rose again for our justification; and there he makes intercession for us. He is the righteous; he who suffered, the just for the unjust, that he might bring us to God. Do not, therefore, despair, but have immediate recourse to God through him.

My little children,.... The apostle may address the saints under this character, on account of their regeneration by the Spirit and grace of God, in which they were as newborn babes; and on account of his being the instrument of their conversion, and so was their spiritual father, and therefore calls them his own children; and he might the rather use such a way of speaking, because of his advanced age, being now in his old age, and John the elder in age as well as in office; as well as to show his paternal affection for them, and care of them, and that what he had wrote, or should write, was not from any disrespect, but from pure love to them; and it might serve to put them in mind of their weakness in faith, in knowledge, and spiritual strength, that they might not entertain high notions of themselves, as if they were perfect and without infirmities; and it is easy to observe, that this is one of Christ's expressions, Joh 13:33, from whose lips the apostle took it, whose words and phrases he greatly delighted in, as he seems to do in this, by his frequent use of it; see Jo1 2:18.

These things write I unto you; concerning the purity and holiness of God, who is light itself; concerning fellowship with him, which no one that lives in sin can have; concerning pardon and cleansing from sin by the blood of Christ, and concerning sin being in them, and they not without it. The Ethiopic version reads, "we write", as in Jo1 1:4;

that ye sin not; not that he thought they could be entirely without it, either without the being of it, or the commission of it, in thought, word, or deed, for this would be to suppose that which is contrary to his own words, in Jo1 1:8; but he suggests that the end of his writing on these subjects was, that they might not live in sin, and indulge themselves in a vicious course of living, give up themselves to it, and walk in it, and work it with all greediness: and nothing could be more suitably adapted to such an end than the consideration of the holiness of God, who calls by his grace; and of the necessity of light and grace and holiness in men to communion with him; and of the pardoning grace of God and cleansing blood of Christ, which, when savingly applied, sets men against sin, and makes them zealous of good works; and of the indwelling of sin in the saints, which puts them upon their guard against it:

and if any man sin; as every man does, even everyone that is in the light, and walks in it, and has fellowship with God; everyone that believes in Christ, and is justified through his righteousness, and pardoned by his blood; everyone of the little children; for the apostle is not speaking of mankind in general who sin, for Christ is not an advocate for all that sin, but of these in particular; hence the Arabic version renders it, "if any of you sin"; and this, with the following, he says not to encourage in sin, but to comfort under a sense of it:

we have an advocate with the Father, Jesus Christ the righteous; Christ is an advocate, not for just or righteous persons, for as he came not to call these to repentance, nor to die for them, so such have no need of an advocate, nor is he one for them; but as he came to call sinners, and to save them, and died for them, the just for the unjust, so he is an advocate, and makes intercession for transgressors; and not for all men, though they have all sinned; not for the world, or those so called in distinction from the persons given him by his Father, for these he prays not; but for all the elect, and whatsoever charges are brought against them he answers to them, and for them; and for all that believe in him, be they weak or strong, even for the apostles as well as others; for they were not without sin, were men of like passions as others, and carried about with them a body of sin, and had their daily infirmities, and so needed an advocate as others; and hence John says, "we have an advocate", &c. but then Christ is not an advocate for sin, though for sinners; he does not vindicate the commission of sin, or plead for the performance of it; he is no patron of iniquity; nor does he deny that his clients have sinned, or affirm that their actions are not sins; he allows in court all their sins, with all their aggravated circumstances; nor does he go about to excuse or extenuate them; but he is an advocate for the non-imputation of them, and for the application of pardon to them: he pleads in their favour, that these sins have been laid upon him, and he has bore them; that his blood has been shed for the remission of them, and that he has made full satisfaction for them; and therefore in justice they ought not to be laid to their charge; but that the forgiveness of them should be applied unto them, for the relief and comfort of their burdened and distressed consciences: and for this he is an advocate for his poor sinning people "with the Father"; who being the first Person, and the Son the advocate, and the Spirit sustaining a like character, is only mentioned; and he being God against whom sin is committed, and to whom the satisfaction is made; and the rather, as he is the Father of Christ, and of those for whom he is an advocate; seeing it may be concluded that his pleadings will be with success, since he is not only related to him, and has an interest in him himself, but the persons also, whose patron he is, are related to him, and have a share in his paternal affection and care: moreover, this phrase, as it expresses the distinct personality of Christ from the Father, so his being with him in heaven at his right hand, and nearness to him; where he discharges this office of his, partly by appearing in person for his people in the presence of God; and partly by carrying in and presenting their confessions of sin, and their prayers for the fresh discoveries and applications of pardoning grace, which he offers up to his Father with the sweet incense of his mediation; and chiefly by pleading the virtue of his blood, righteousness, and sacrifice, which are carried within the vail, and are always in sight, and call aloud for peace and pardon; as also by answering and removing the charges and accusations of the court adversary, the accuser of the brethren, the devil; as well as by the declarations of his will, demanding in point of justice, in consideration of his sufferings and death, that such and such blessings be bestowed upon his people, as pardon, righteousness, grace, and supplies of grace, and at last glory; and by applying these benefits to their souls as a "comforter", which the word here used also signifies, and is so rendered, Joh 14:16; and by the Arabic version here. Now the saints have but one advocate, and that is enough for them; the apostle does not say we have advocates, but "an advocate"; not angels, nor saints departed, but Jesus Christ only, who is the one Mediator between God and man, Ti1 2:5, and he is a continual one, he ever lives to make intercession; his blood is always speaking, and he always pleading; and therefore it is said "we have", not we have had, or we shall have an advocate and he is a prevalent one, he is always heard, he thoroughly pleads the cause he undertakes, and ever carries it; which is owing to the dignity of his person, his interest with his Father, and the virtue and value of his sacrifice: and he every way fit for such a work, for he is "righteous"; not only in his natures, both divine and human, but in his office, as Mediator, which he faithfully and righteously performs; he is a very proper person to plead for guilty persons, which he could not do if he himself was guilty; but he is so holy and righteous that nothing can be objected to him by God; and it need not be doubted by men that he will act the faithful part to them, and righteously serve them and their cause; and it is moreover his righteousness which he has wrought out, and is imputed to them, that carries the cause for them; and therefore this character of Christ fitly added, as is also the following. The Jews (i) have adopted the word in the text into their language, but have applied it to a different purpose, to alms deeds, repentance, and good works. Much more agreeably Philo the Jew (k) speaks of the son of perfect virtue, "as an advocate" for the forgiveness of sins, and for a supply of everlasting good things.
