1 John 2:8-11

8On 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.

9The one who says he is in the light but still hates his fellow Christian is still in the darkness.

10The one who loves his fellow Christian resides in the light, and there is no cause for stumbling in him.

11But 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.
