Sure God is my best friend, I got a lot of best friends, santa clause if my best friend in december, the tooth fairy is ok but not quite a best friend especially after I lost my baby teeth. Satan is a best friend in the same catagory, as God, Zues, Apollo, eVen Uranus.
I think when God becomes your best friend, he gets a little jealous and don't want you to have any other best friends before his face, He will smite them and you down if he catches you, kiss all other best friend good by if you let him run thing you have to set bounderies, even for best friends.
