7 Dear friends, I am not writing a new commandment to you, but an old commandment which you have had from the beginning. The old commandment is the word that you have already heard. 8 On the other hand, I am writing a new commandment to you which is true in him and in you, because the darkness is passing away and the true light is already shining. 9 The one who says he is in the light but still hates his fellow Christian is still in the darkness. 10 The one who loves his fellow Christian resides in the light, and there is no cause for stumbling in him. 11 But the one who hates his fellow Christian is in the darkness, walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.
5 Now this is the gospel message we have heard from him and announce to you: God is light, and in him there is no darkness at all. 6 If we say we have fellowship with him and yet keep on walking in the darkness, we are lying and not practicing the truth. 7 But if we walk in the light as he himself is in the light, we have fellowship with one another and the blood of Jesus his Son cleanses us from all sin. 8 If we say we do not bear the guilt of sin, we are deceiving ourselves and the truth is not in us. 9 But if we confess our sins, he is faithful and righteous, forgiving us our sins and cleansing us from all unrighteousness. 10 If we say we have not sinned, we make him a liar and his word is not in us.
