1 John 3:8

8 Everyone who commits sin is a child of the devil; for the devil has been sinning from the beginning. The Son of God was revealed for this purpose, to destroy the works of the devil.

1 John 3:8 In-Context

6 No one who abides in him sins; no one who sins has either seen him or known him.
7 Little children, let no one deceive you. Everyone who does what is right is righteous, just as he is righteous.
8 Everyone who commits sin is a child of the devil; for the devil has been sinning from the beginning. The Son of God was revealed for this purpose, to destroy the works of the devil.
9 Those who have been born of God do not sin, because God's seed abides in them; they cannot sin, because they have been born of God.
10 The children of God and the children of the devil are revealed in this way: all who do not do what is right are not from God, nor are those who do not love their brothers and sisters.
