{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.

People's New Testament

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.

Wesley's Notes

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?

Jamieson-Fausset-Brown Bible Commentary

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.

Matthew Henry's Concise Commentary

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.
