Whoever commits sin transgresses the law, for sin is the transgression of the law.
1 John 3:4
Those who have been born of God do not sin, because His Holy Spirit remains in him and he is not able to sin because he is born of God. 1 John 3:9
Whoever abides in the Holy Spirit does not sin. Whoever sins has not seen Him, nor known Him.
Let no man deceive you. He that does righteousness is righteous, even as Jesus is righteous. He that commits sin is of the devil, for the devil sinned from the beginning.
The Son of God was brought forth that He might destroy the works of the devil. 1 John 3:7-8a
