1 John 1:8; 1 John 3:3; 1 John 5:10; 1 John 5:18; 1 John 5:21

8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
3 And every man that hath this hope in him purifieth himself, even as he is pure.
10 He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.
18 We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.
21 Little children, keep yourselves from idols. Amen.
