From now on when you hear a Christian say “I am a sinner” just ask this question and give them these two verses:
Are you born of God or are you of the devil?
He that commits sin is of the devil; for the devil has been sinning from the very beginning. 1 John 3:8
Whoever is born of God does not commit sin ; for God’s seed remains in him and he CANNOT SIN, because he is born of God. 1 John 3:9
You can’t be both born of God and of the devil, THEREFORE YOU ARE EITHER A SINNER OR NOT A SINNER!
So which one are you?
