1 John 2:8-11

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. Anyone who claims to be in the light but hates a brother or sister is still in the darkness. Anyone who loves their brother and sister lives in the light, and there is nothing in them to make them stumble. 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.
