But if we walk in the light. He now says, that the proof of our union with God is certain, if we are conformable to him; not that purity of life conciliates us to God, as the prior cause; but the Apostle means, that our union with God is made evident by the effect, that is, when his purity shines forth in us. And, doubtless, such is the fact; wherever God comes, all things are so imbued with his holiness, that he washes away all filth; for without him we have nothing but filth and darkness. It is hence evident, that no one leads a holy life, except he is united to God. In saying, We have fellowship one with another, he does not speak simply of men; but he sets God on one side, and us on the other. It may, however, be asked, "Who among men can so exhibit the light of God in his life, as that this likeness which John requires should exist; for it would be thus necessary, that he should be wholly pure and free from darkness." To this I answer, that expressions of this kind are accommodated to the capacities of men; he is therefore said to be like God, who aspires to his likeness, however distant from it he may as yet be. The example ought not to be otherwise applied than according to this passage. He walks in darkness who is not ruled by the fear of God, and who does not, with a pure conscience, devote himself wholly to God, and seek to promote his glory. Then, on the other hand, he who in sincerity of heart spends his life, yea, every part of it, in the fear and service of God, and faithfully worships him, walks in the light, for he keeps the right way, though he may in many things offend and sigh under the burden of the flesh. Then, integrity of conscience is alone that which distinguishes light from darkness. And the blood of Jesus Christ After having taught what is the bond of our union with God, he now shews what fruit flows from it, even that our sins are freely remitted. And this is the blessedness which David describes in the thirty-second Psalm, in order that we may know that we are most miserable until, being renewed by God's Spirit, we serve him with a sincere heart. For who can be imagined more miserable than that man whom God hates and abominates, and over whose head is suspended both the wrath of God and eternal death? This passage is remarkable; and from it we first learn, that the expiation of Christ, effected by his death, does then properly belong to us, when we, in uprightness of heart, do what is right and just for Christ is no redeemer except to those who turn from iniquity, and lead a new life. If, then, we desire to have God propitious to us, so as to forgive our sins, we ought not to forgive ourselves. In short, remission of sins cannot be separated from repentance, nor can the peace of God be in those hearts, where the fear God does not prevail. Secondly, this passage shews that the gratuitous pardon of sins is given us not only once, but that it is a benefit perpetually residing in the Church, and daily offered to the faithful. For the Apostle here addresses the faithful; as doubtless no man has ever been, nor ever will be, who can otherwise please God, since all are guilty before him; for however strong a desire there may be in us of acting rightly, we always go haltingly to God. Yet what is half done obtains no approval with God. In the meantime, by new sins we continually separate ourselves, as far as we can, from the grace of God. Thus it is, that all the saints have need of the daily forgiveness of sins; for this alone keeps us in the family of God. By saying, from all sin, he intimates that we are, on many accounts, guilty before God; so that doubtless there is no one who has not many vices. But he shews that no sins prevent the godly, and those who fear God, from obtaining his favor. He also points out the manner of obtaining pardon, and the cause of our cleansing, even because Christ expiated our sins by his blood; but he affirms that all the godly are undoubtedly partakers of this cleansing. The whole of his doctrine has been wickedly perverted by the sophists; for they imagine that pardon of sins is given us, as it were, in baptism. They maintain that there only the blood of Christ avails; and they teach, that after baptism, God is not otherwise reconciled than by satisfactions. They, indeed, leave some part to the blood of Christ; but when they assign merit to works, even in the least degree, they wholly subvert what John teaches here, as to the way of expiating sins, and of being reconciled to God. For these two things can never harmonize together, to be cleansed by the blood of Christ, and to be cleansed by works: for John assigns not the half, but the whole, to the blood of Christ. The sum of what is said, then, is, that the faithful know of a certainty, that they are accepted by God, because he has been reconciled to them through the sacrifice of the death of Christ. And sacrifice includes cleansing and satisfaction. Hence the power and efficiency of these belong to the blood of Christ alone. Hereby is disproved and exposed the sacrilegious invention of the Papists as to indulgences; for as though the blood of Christ were not sufficient, they add, as a subsidy to it, the blood and merits of martyrs. At the same time, this blasphemy advances much further among us; for as they say that their keys, by which they hold as shut up the remission of sins, open a treasure made up partly of the blood and merits of martyrs, and partly of the worlds of supererogation, by which any sinner may redeem himself, no remission of sins remains for them but what is derogatory to the blood of Christ; for if their doctrine stands, the blood of Christ does not cleanse us, but comes in, as it were, as a partial aid. Thus consciences are held in suspense, which the Apostle here bids to rely on the blood of Christ.

But if we walk in the light - Compare the notes at 1-John 1:5. Walking in the light may include the three following things:
(1) Leading lives of holiness and purity; that is, the Christian must be characteristically a holy man, a light in the world, by his example.
(2) walking in the truth; that is, embracing the truth in opposition to all error of paganism and infidelity, and having clear, spiritual views of truth, such as the unrenewed never have. See 2-Corinthians 4:6; 1-Corinthians 2:9-15; Ephesians 1:18.
(3) enjoying the comforts of religion; that is, having the joy which religion is fitted to impart, and which it does impart to its true friends, Psalm 94:19; Isaiah 57:8; 2-Corinthians 1:3; 2-Corinthians 13:11. Compare the notes at John 12:35.
As he is in the light - In the same kind of light that he has. The measure of light which we may have is not the same in degree, but it is of the same kind. The true Christian in his character and feelings resembles God.
We have fellowship one with another - As we all partake of his feelings and views, we shall resemble each other. Loving the same God, embracing the same views of religion, and living for the same ends, we shall of course have much that is common to us all, and thus shall have fellowship with each other.
And the blood of Jesus Christ his Son cleanseth us from all sin - See the sentiment here expressed fully explained in the notes at Hebrews 9:14. When it is said that his blood cleanses us from all sin, the expression must mean one of two things - either that it is through that blood that all past sin is forgiven, or that that blood will ultimately purify us from all transgression, and make us perfectly holy. The general meaning is plain, that in regard to any and every sin of which we may be conscious, there is efficacy in that blood to remove it, and to make us wholly pure. There is no stain made by sin so deep that the blood of Christ cannot take it entirely away from the soul. The connection here, or the reason why this is introduced here, seems to be this: The apostle is stating the substance of the message which he had received, 1-John 1:5. The first or leading part of it was, that God is light, and in him is no darkness, and that his religion requires that all his friends should resemble him by their walking in the light. Another, and a material part of the same message was, that provision was made in his religion for cleansing the soul from sin, and making it like God. No system of religion intended for man could be adapted to his condition which did not contain this provision, and this did contain it in the most full and ample manner. Of course, however, it is meant that that blood cleanses from all sin only on the conditions on which its efficacy can be made available to man - by repentance for the past, and by a cordial reception of the Saviour through faith.

But if we walk in the light - If, having received the principle of holiness from him, we live a holy and righteous life, deriving continual light, power, and life from him, then we have fellowship one with another; that is, we have communion with God, and God condescends to hold communion with us. This appears to be the intention of the apostle; and so he was understood by some versions and MSS., which, instead of μετ' αλληλων, with each other, have μετ' αυτον, with him. Those who are deeply experienced in Divine things converse with God, and God with them. What John says is no figure; God and a holy heart are in continual correspondence.
The blood of Jesus Christ - The meritorious efficacy of his passion and death has purged our consciences from dead works, and cleanseth us, καθαριζει ἡμας, continues to cleanse us, i.e., to keep clean what it has made clean, (for it requires the same merit and energy to preserve holiness in the soul of man, as to produce it), or, as several MSS. and some versions read, καθαριει and καθαρισει, will cleanse; speaking of those who are already justified, and are expecting full redemption in his blood.
And being cleansed from all sin is what every believer should look for, what he has a right to expect, and what he must have in this life, in order to be prepared to meet his God. Christ is not a partial Savior, he saves to the uttermost, and he cleanses from All sin.

But if we walk in the (d) light, as he is in the light, we have fellowship one with another, (4) and the blood of Jesus Christ his Son cleanseth us from all sin.
(d) God is said to be light by his own nature, and to be in light, that is to say, in that everlasting infinite blessedness: and we are said to walk in light in that the beams of that light shine to us in the Word. (4) A digression the matter at hand, to the remission of sins: for this our sanctification who walk in the light, is a testimony of our joining and knitting together with Christ: but because this our light is very dark, we must obtain another benefit in Christ, that is, that our sins may be forgiven us being sprinkled with his blood: and this in conclusion is the support and anchor of our salvation.

But if we walk in the light,.... Are persons enlightened by the Spirit of God, so as to have a true sight and sense of sin, to know Christ, and the way of salvation by him; and are children of the light, and are going on and increasing in spiritual light and knowledge; walk on in Christ, the light, by faith, and in the light and truth of the Gospel, and as becomes it, and as children of light; and as such who are called out of darkness into marvellous light:
as he is in the light; according to the light which he has given, who is light itself, is in it, and dwells in it. This "as" denotes not equality, but likeness: when this is the case, then it is a clear point, that
we have fellowship one with another; not with the saints, with the apostles, and other Christians, but with God: "we have mutual communion", as the Arabic version renders it; God with us, and we with him. Some copies read, "with him", as in 1-John 1:6; and such a reading the sense requires; and agreeably to this the Ethiopic version renders it, "and we are partakers among ourselves with him"; that is, we all jointly and mutually appear to be like him, and partake of his nature, and have communion with him; and not only so, but with his Son Jesus Christ, as appears from our having a share in the cleansing efficacy of his blood:
and the blood of Jesus Christ, his Son, cleanseth us from all sin: there is a pollution on human nature, which is original, natural, universal, and internal, and is such that nothing can remove but the blood of Christ; not ceremonial ablutions and sacrifices, nor moral duties, nor evangelical performances, or submission to Gospel ordinances, and particularly baptism, which is not the putting away the faith of the flesh; nor even the graces of the Spirit, no, not faith, no otherwise than as it has to do with this blood; for this cleansing is not to be understood of sanctification, for that more properly belongs to the Spirit of God, and besides, does not cleanse from all sin; for notwithstanding this, sin is in the saints: but either of the atonement of sin, by the sacrifice of Christ, and so of a complete justification from it by his blood, which is put for both his active and passive obedience, the one being finished in the other; or rather of the pardon of sin, procured by the blood of Christ, and the application of that blood to the conscience, which purges it from dead works, and which has a continued virtue in it for that purpose. Christ's blood, being applied by the Spirit of God, has been always cleansing from sin; it had this virtue in it, and was of this use, even before it was actually shed, to the Old Testament saints; whence Christ is said to be the Lamb slain from the foundation of the world; and it has the same efficacy now as when first shed, and will have to the end of the world; and being sprinkled upon the conscience, by the Spirit of God, it takes away the sins of believers, and cleanses from them, as fast as the corruption of nature rises, or sins appear; and removes them out of their sight, and speaks peace to their souls; and which is owing, as to the dignity of Christ's person and the value of his sacrifice, so to his continual intercession, advocacy, and mediation; and which reaches to all sin, original and actual, secret and open sins; sins of heart, thought, lip, and life; sins of omission and commission, greater or lesser sins, committed against light and knowledge, grace and mercy, law and Gospel, all but the sin against the Holy Ghost; and in this Christ was the antitype of the scape goat, of which the Jews say (g), that
"it atoned for all the transgressions of the law, whether small or great, sins of presumption, or of ignorance, known, or not known, which were against an affirmative or negative command, which deserved cutting off (by the hand of God), or death by the sanhedrim.''
The Arabic and Ethiopic versions render it, "from all our sins"; and this must be ascribed to the greatness of his person, as the Son of God; wherefore the emphasis lies on these words, "his Son": the Son of God, who is equal with God, and is truly and properly God: as it must be the blood of man that must, according to the law, be shed, to atone for and expiate sin, and cleanse from it, and that of an innocent man, who is holy, harmless, and without sin; so it must not be the blood of a mere man, though ever so holy, but the blood of one that is God as well as man; see Acts 20:28. The divine nature of the Son of God, being in union with the human nature, put virtue into his blood to produce such an effect, which still continues, and will, as long as there is any occlusion for it.

Compare Ephesians 5:8, Ephesians 5:11-14. "WE WALK"; "God is (essentially in His very nature as 'the light,' 1-John 1:5) in the light." WALKING in the light, the element in which God Himself is, constitutes the test of fellowship with Him. Christ, like us, walked in the light (1-John 2:6). ALFORD notices, Walking in the light as He is in the light, is no mere imitation of God, but an identity in the essential element of our daily walk with the essential element of God's eternal being.
we have fellowship one with another--and of course with God (to be understood from 1-John 1:6). Without having fellowship with God there can be no true and Christian fellowship one with another (compare 1-John 1:3).
and--as the result of "walking in the light, as He is in the light."
the blood of Jesus . . . cleanseth us from all sin--daily contracted through the sinful weakness of the flesh, and the power of Satan and the world. He is speaking not of justification through His blood once for all, but of the present sanctification ("cleanseth" is present tense) which the believer, walking in the light and having fellowship with God and the saints, enjoys as His privilege. Compare John 13:10, Greek, "He that has been bathed, needeth not save to wash his feet, but is clean every whit." Compare 1-John 1:9, "cleanse us from all unrighteousness," a further step besides "forgiving us our sins." Christ's blood is the cleansing mean, whereby gradually, being already justified and in fellowship with God, we become clean from all sin which would mar our fellowship with God. Faith applies the cleansing, purifying blood. Some oldest manuscripts omit "Christ"; others retain it.

But if we walk in the light - In all holiness. As God is (a deeper word than walk, and more worthy of God) in the light, then we may truly say, we have fellowship one with another - We who have seen, and you who have not seen, do alike enjoy that fellowship with God. The imitation of God being the only sure proof of our having fellowship with him. And the blood of Jesus Christ his Son - With the grace purchased thereby. Cleanseth us from all sin - Both original and actual, taking away all the guilt and all the power.
