1 John 2:8-11

Again, a new commandment write I unto you, which thing is true in him and in you; because the darkness is passing away, and the true light already shineth. He that saith he is in the light and hateth his brother, is in the darkness even until now. He that loveth his brother abideth in the light, and there is no occasion of stumbling in him. But he that hateth his brother is in the darkness, and walketh in the darkness, and knoweth not whither he goeth, because the darkness hath blinded his eyes.
