Small Thought.  Satan is worried because human beings are
excelling in their assignment.
At the beginning, he was striving for such results as the beheading,
the killing, the kidnaping, the burning, the raping.....It was
beyond his expectations. But now he is afraid for his position
and  he is scared to death to be replaced by his mortal followers.
He doesn't appreciate at all this competition.  Viva
