To Destroy the Works of the Devil

The settled course of a sinful life is not merely a personal failing or an unfortunate habit; it places one in fellowship with the devil himself. This is the deeper spiritual context of the practice of sin, as John warns his readers in today’s passage.

“Little children, let no one deceive you,” the Apostle writes (1 John 3:7). The deception in view is the suggestion that righteous practice is optional for the truly spiritual person, that those with higher knowledge can dispense with the simple ethics of obedience. False teachers in John’s day pressed exactly this view. John refuses to allow it: “Whoever practices righteousness is righteous, as he is righteous.” The character of one’s life reveals the character of one’s heart. Habitual righteousness is the mark of those who share, by union with Christ, in His own righteousness.

The contrast follows in verse 8: “Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning.” This is sober language. John is not saying that every individual sin places one in the devil’s camp; he has already taught that even genuine believers continue to sin and find ongoing forgiveness in Christ (1:8–10). He is speaking of the settled course of life, the pattern of sin that shows where one’s deepest loyalties lie. To live habitually in sin is to walk in step with the devil, who has himself been sinning since the beginning.

The reference to “the beginning” reaches back to the rebellion in the garden, when the devil drew our first parents into sin and so introduced lawlessness into the human race. Since his fall, the devil’s whole history has been a history of sin, of opposition to the holy will of God. Those whose lives are characterized by this same opposition share in the devil’s pattern of life and, by John’s logic, share in his nature.

But the verse does not end with this dark assessment. John concludes with a triumphant statement of Christ’s purpose: “The reason the Son of God appeared was to destroy the works of the devil” (3:8). The eternal Son entered the world precisely to undo what the devil has done. Christ’s incarnation, ministry, death, and resurrection together accomplished the destruction of the devil’s grip on those whom he had bound, the unraveling of his works in the lives of God’s people. To belong to Christ is to belong to the One who has come to dismantle the dominion of darkness, and to be drawn out of that dominion altogether.
