1 John 1:6; 1 John 1:7; 1 John 2:6; 1 John 2:11

1 John 1:6

6 If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:

1 John 1:7

7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.

1 John 2:6

6 He that saith he abideth in him ought himself also so to walk, even as he walked.

1 John 2:11

11 But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes.
