He that committeth sin - Habitually, willfully, characteristically.

Is of the devil - This cannot mean that no one who commits any sin, or who is not absolutely perfect, can be a Christian, for this would cut off the great mass, even according to the belief of those who hold that the Christian may be perfectly holy, from all claim to the Christian character. But what the apostle here says is true in two senses:

(1) That all who commit sin, even true believers, so far as they are imperfect, in this respect resemble Satan, and are under his influence, since sin, just so far as it exists at all, makes us resemble him.

(2) all who habitually and characteristically sin are of the devil." This latter was evidently the principal idea in the mind of the apostle. His object here is to show that those who sinned, in the sense in which it would seem some maintained that the children of God might sin, could have no real evidence of piety, but really belonged to Satan.

For the devil sinneth from the beginning - The beginning of the world; or from the first account we have of him. It does not mean that he sinned from the beginning of his existence, for he was made holy like the other angels. Notes, Jde 1:6. The meaning is, that he introduced sin into the universe, and that he has continued to practice it ever since. The word sinneth here implies continued and habitual sin. He did not commit one act of sin and then reform; but he has continued, and still continues, his course of sin. This may confirm what has been already said about the kind of sin that John refers to. He speaks of sinning habitually, continuously, willfully; and anyone who does this shows that he is under the influence of him whose characteristic it has been and is to sin.

For this purpose the Son of God was manifested - Became incarnate, and appeared among people, 1 John 3:5. Compare the notes at 1 Timothy 3:16.

That he might destroy the works of the devil - All his plans of wickedness, and his control over the hearts of people. Compare the Matthew 8:29 note; Mark 1:24 note; Hebrews 2:14 note. The argument here is, that as the Son of God came to destroy all the works of the devil, he cannot be his true follower who lives in sin.

He that committeth sin is of the devil - Hear this, also, ye who plead for Baal, and cannot bear the thought of that doctrine that states believers are to be saved from all sin in this life! He who committeth sin is a child of the devil, and shows that he has still the nature of the devil in him; for the devil sinneth from the beginning - he was the father of sin, brought sin into the world, and maintains sin in the world by living in the hearts of his own children, and thus leading them to transgression; and persuading others that they cannot be saved from their sins in this life, that he may secure a continual residence in their heart. He knows that if he has a place there throughout life, he will probably have it at death; and, if so, throughout eternity.

For this purpose - Εις τουτο· For this very end - with this very design, was Jesus manifested in the flesh, that he might destroy, ἱνα λυσῃ, that he might loose, the bonds of sin, and dissolve the power, influence, and connection of sin. See on 1 John 3:3 (note).

He that committeth sin is of the devil,.... Not everyone that sins, or commits acts of sin, then every man is of the devil, because no man lives without the commission of sin; but he who makes sin his constant business, and the employment of his life, whose life is a continued series of sinning, he is of the devil; not as to origin and substance, or by proper generation, as some have literally understood the words; but by imitation, being like him, and so of him their father, doing his lusts, living continually in sin, as he does, and so resemble him, as children do their parents; and hereby also appear to be under his government and influence, to be led captive by him at his will, and so to belong to him, and such as will have their part and portion with him in the lake which burns with fire and brimstone, so living and dying:

for the devil sinneth from the beginning; not of his creation, for he was made by God a pure and holy creature; but from the beginning of the world, or near it, at least from the beginning of man's creation; for he not only sinned by rebelling against God himself, and by drawing in the rest of the apostate angels into the rebellion with him, but by tempting man, as soon as created, to sin against God: what was his first and particular sin is not certain, whether pride or envy, or what; seems to be, his not abiding in the truth, or an opposition to the truth of the Gospel, respecting the incarnation of the Son of God, mentioned in the following clause; see John 8:44; however, he has been continually sinning ever since: he "sinneth"; he is always sinning, doing nothing else but sin; so that he that lives a vicious course of life is like him, and manifestly of him:

for this purpose the Son of God was manifested; in human nature, as in 1 John 3:5; whence it appears that he was the Son of God before his incarnation, and so not by it; he did not become so through it, nor was he denominated such on account of it; he was not made the Son of God by it, but was manifested in it what he was before; and for this end:

that he might destroy the works of the devil; and the devil himself, and all his dominion and power, and particularly his power over death, and death itself; and especially the sins of men, which are the works of the devil, which he puts them upon, influences them to do, and takes delight in; and which are destroyed by Christ, by his sacrifice and death, being taken, carried, removed away, finished, and made an end of by him; See Gill on 1 John 3:5.

The Devil

See on 1 John 2:13. Compare John 8:44. "The devil made no one, he begot no one, he created no one; but whosoever imitates the devil, is, as it were, a child of the devil, through imitating, not through being born of him" (Augustine).

Sinneth

The present tense indicates continuousness. He sinned in the beginning, and has never ceased to sin from the beginning, and still sinneth.

The Son of God

For the first time in the Epistle. Hitherto the title has been the Son, or His Son. See on 1 John 1:7.

Might destroy (λύσῃ)

Lit., dissolve, loosen. Compare Acts 27:41; Acts 13:43. "The works of the devil are represented as having a certain consistency and coherence. They show a kind of solid front. But Christ, by His coming, has revealed them in their complete unsubstantiality. He has 'undone' the seeming bonds by which they were held together" (Westcott).

{8} He that committeth sin is of the {i} devil; for the devil {k} sinneth from the {l} beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.

(8) An argument taken by contrast: the devil is the author of sin, and therefore he is that serves sin is of the devil, or is ruled by the inspiration of the devil: and if he is the devil's son, then is he not God's son: for the devil and God are so contrary to one another that the Son of God was sent to destroy the works of the devil. Therefore on the other side, whoever resists sin, is the son of God, being born again of his Spirit as of new seed, in so much, that by necessity he is now delivered from the slavery of sin.

(i) Resembles the devil, as the child does the father, and is governed by his Spirit.

(k) He says not sinned but sins for he does nothing else but sin.

(l) From the very beginning of the world.

3:8 He that committeth sin is of the devil. A sinful life is a proof of the devil's power. Christ came to destroy the works of the devil, and it is his work to destroy sin in all his disciples.

3:8 He that committeth sin is a child of the devil; for the devil sinneth from the beginning - That is, was the first sinner in the universe, and has continued to sin ever since. The Son of God was manifested to destroy the works of the devil - All sin. And will he not perform this in all that trust in him?

8. He that committeth sin is of the devil-in contrast to "He that doeth righteousness," 1Jo 3:7. He is a son of the devil (1Jo 3:10; Joh 8:44). John does not, however, say, "born of the devil." as he does "born of God," for "the devil begets none, nor does he create any; but whoever imitates the devil becomes a child of the devil by imitating him, not by proper birth" [Augustine, Ten Homilies on the First Epistle of John, Homily 4.10]. From the devil there is not generation, but corruption [Bengel].

sinneth from the beginning-from the time that any began to sin [Alford]: from the time that he became what he is, the devil. He seems to have kept his first estate only a very short time after his creation [Bengel]. Since the fall of man [at the beginning of our world] the devil is (ever) sinning (this is the force of "sinneth"; he has sinned from the beginning, is the cause of all sins, and still goes on sinning; present). As the author of sin, and prince of this world, he has never ceased to seduce man to sin [Luecke].

destroy-break up and do away with; bruising and crushing the serpent's head.

works of the devil-sin, and all its awful consequences. John argues, Christians cannot do that which Christ came to destroy.

3:3-10 The sons of God know that their Lord is of purer eyes than to allow any thing unholy and impure to dwell with him. It is the hope of hypocrites, not of the sons of God, that makes allowance for gratifying impure desires and lusts. May we be followers of him as his dear children, thus show our sense of his unspeakable mercy, and express that obedient, grateful, humble mind which becomes us. Sin is the rejecting the Divine law. In him, that is, in Christ, was no sin. All the sinless weaknesses that were consequences of the fall, he took; that is, all those infirmities of mind or body which subject man to suffering, and expose him to temptation. But our moral infirmities, our proneness to sin, he had not. He that abides in Christ, continues not in the practice of sin. Renouncing sin is the great proof of spiritual union with, continuance in, and saving knowledge of the Lord Christ. Beware of self-deceit. He that doeth righteousness is righteous, and to be a follower of Christ, shows an interest by faith in his obedience and sufferings. But a man cannot act like the devil, and at the same time be a disciple of Christ Jesus. Let us not serve or indulge what the Son of God came to destroy. To be born of God is to be inwardly renewed by the power of the Spirit of God. Renewing grace is an abiding principle. Religion is not an art, a matter of dexterity and skill, but a new nature. And the regenerate person cannot sin as he did before he was born of God, and as others do who are not born again. There is that light in his mind, which shows him the evil and malignity of sin. There is that bias upon his heart, which disposes him to loathe and hate sin. There is the spiritual principle that opposes sinful acts. And there is repentance for sin, if committed. It goes against him to sin with forethought. The children of God and the children of the devil have their distinct characters. The seed of the serpent are known by neglect of religion, and by their hating real Christians. He only is righteous before God, as a justified believer, who is taught and disposed to righteousness by the Holy Spirit. In this the children of God are manifest, and the children of the devil. May all professors of the gospel lay these truths to heart, and try themselves by them.
