1 John 1:10; 1 John 2:1; 1 John 3:6; 1 John 3:8-9; 1 John 5:16; 1 John 5:18

10 If we say that we have not sinned , we make him a liar, and his word is not in us.
1 My little children, these things write I unto you, that ye sin not. And if any man sin , we have an advocate with the Father, Jesus Christ the righteous:
6 Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.
8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested , that he might destroy the works of the devil. 9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin , because he is born of God.
16 If any man see his brother sin a sin which is not unto death, he shall ask , and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it.
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.
