1 John 1:6; 1 John 1:8; 1 John 1:10; 1 John 4:20

6 If we say that we have fellowship with him, and walk in darkness, we lie , and do not the truth:
8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
10 If we say that we have not sinned , we make him a liar, and his word is not in us.
20 If a man say , I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen , how can he love God whom he hath not seen ?
