The one who practices sin [separating himself from God, and offending Him by acts of disobedience, indifference, or rebellion] is of the devil [and takes his inner character and moral values from him, not God]; for the devil has sinned and violated God’s law from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil.
[But] he who commits sin [who practices evildoing] is of the devil [takes his character from the evil one], for the devil has sinned (violated the divine law) from the beginning. The reason the Son of God was made manifest (visible) was to undo (destroy, loosen, and dissolve) the works the devil [has done].
The person who keeps on sinning is from the Adversary, because from the very beginning the Adversary has kept on sinning. It was for this very reason that the Son of God appeared, to destroy these doings of the Adversary.
Anyone who ·continues to sin [or sins] belongs to the devil [John 8:44], because the devil has been sinning since the beginning. The Son of God ·came [was revealed; appeared] for this purpose: to destroy the devil’s work [Matt. 4:1–11; 12:25–29; Luke 10:18; John 12:31; Rev. 12:7–12; 20:1–3].
You, my children, are younger than I am, and I don’t want you to be taken in by any clever talk just here. The man who lives a consistently good life is a good man, as surely as God is good. But the man whose life is habitually sinful is spiritually a son of the devil, for the devil is behind all sin, as he always has been. Now the Son of God came to earth with the express purpose of liquidating the devil’s activities. The man who is really God’s son does not practise sin, for God’s nature is in him, for good, and such a heredity is incapable of sin.
So, my dear children, don’t let anyone divert you from the truth. It’s the person who acts right who is right, just as we see it lived out in our righteous Messiah. Those who make a practice of sin are straight from the Devil, the pioneer in the practice of sin. The Son of God entered the scene to abolish the Devil’s ways.
The one persisting in sin belongs to the diabolical one, who has been all about sin from the beginning. That is why the Son of God came into our world: to destroy the plague of destruction inflicted on the world by the diabolical one.
