1 JOHN 3:7–10 CHILDREN OF GOD AND CHILDREN OF THE DEVIL
7 Little children, let no one deceive you; the one who practices righteousness is righteous, just as He is righteous;
8 the one who practices sin is of the devil; for the devil has been sinning from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil.
9 No one who has been born of God practices sin, because His seed remains in him; and he cannot keep on sinning, because he has been born of God.
10 By this the children of God and the children of the devil are obvious: anyone who does not practice righteousness is not of God, nor the one who does not love his brother.
John here issues a warning that feels almost like a guardrail across the road of deception: “let no one deceive you.” Truth is not only to be believed, but protected. He then gives a simple moral principle—righteousness reveals righteousness. The one who practices what is right is aligned with the righteous character of Christ. This is not about occasional moments, but a pattern of life that reflects its source.
On the other side, John speaks just as plainly: “the one who practices sin is of the devil.” This is strong language, but it is meant to expose the spiritual reality behind moral direction. He explains that the devil has been sinning from the beginning, meaning that sin is not neutral or random, but has an origin in rebellion against God. Into that setting, John places the appearing of Christ: “The Son of God appeared for this purpose, to destroy the works of the devil.” The mission of Jesus is not just correction but active overthrow of the kingdom of darkness.
That word “destroy” is significant—it carries the idea of dismantling or breaking the hold of something. History gives us pictures of powers being overthrown—empires collapsing, systems ending—but John is speaking of something deeper than Rome or any earthly regime. Only Christ enters history with the authority to dismantle the works of the devil at their source.
John then speaks about identity shaped by new birth: “No one who has been born of God practices sin.” The language here points to a continuing pattern rather than isolated failure. The reason is given: “His seed remains in him.” Something has been implanted by God that changes direction over time. The life of God is not temporary influence but ongoing presence. Because of this, the person “cannot keep on sinning” in the same settled way, because new life produces new direction.
This does not mean struggle disappears, but it does mean allegiance changes. A life that belongs to God cannot be comfortable in ongoing rebellion. There is an internal resistance now, a conflict that did not exist before. John’s point is deep: this is not emotional development, but spiritual rebirth.
Finally, John draws a clear dividing line: “By this the children of God and the children of the devil are obvious.” The distinction is not hidden or complicated. It is seen in practice—righteousness versus sin, love versus indifference. He brings it down to two visible markers: righteousness practiced and love for one another. These reveal identity more clearly than words ever can.
So the message is unmistakable: Christ came to destroy the works of the devil, and those who belong to Him will increasingly reflect that breaking of sin’s dominion in their lives (1 John 3:7-10).
