1 John 2:8-11

ISV(i) 8 On the other hand, I am writing to you a new commandment that is truly in him and in you. For the darkness is fading away, and the true light is already shining.
9 The person who says that he is in the light but hates his brother is still in the darkness. 10 The person who loves his brother abides in the light, and there is no reason for him to stumble. 11 But the person who hates his brother is in the darkness and lives in the darkness. He does not know where he is going, because the darkness has blinded his eyes.
