The Bible also says that he who professes to love God yet hates his brother is a LIAR.
I am not writing to tell you of any new command, brothers of mine. It is the old command which you had at the beginning; it is the old message which you have heard before. And yet as I write it to you again I know that it is true--in your life as it was in his. For the darkness is beginning to lift and the true light is already shinning. Anyone who claims to be "in the light" and hates his brother is, in fact, still in complete darkness. The man who loves his brother lives in the light, and has no reason to stumble. But the man who hates his brother is shut off from the light and gropes his way in the dark without knowing where he is going. For the darkness has made him blind.
