7 Dear friends, I am not writing you a new command but an old one, which you have had since the beginning. This old command is the message you have heard. 8 Yet I am writing you a new command; its truth is seen in him and in you, because the darkness is passing and the true light is already shining.
9 Anyone who claims to be in the light but hates a brother or sister[a] is still in the darkness. 10 Anyone who loves their brother and sister[b] lives in the light, and there is nothing in them to make them stumble. 11 But anyone who hates a brother or sister is in the darkness and walks around in the darkness. They do not know where they are going, because the darkness has blinded them.
