19 They went out from us, but they were not of us; for if they had been of us, they would have continued with us. But they went out, that it might become plain that they all are not of us.

4 Everyone who makes a practice of sinning also practices lawlessness; sin is lawlessness. 5 You know that he appeared in order to ^mtake away sins, and ⁿin him there is no sin. 6 ^oNo one who abides in him keeps on sinning; no one who keeps on sinning has either ^pseen him or known him. 7 Little children, let no one ^qdeceive you. ^rWhoever practices righteousness is righteous, as he is righteous. 8 Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning. The reason the Son of God appeared was to ^sdestroy the works of the devil. 9 No one born of God makes a practice of sinning, for God’s¹ seed abides in him; and he cannot keep on sinning, because he has been born of God. 10 By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, nor is the one who does not love his brother.
