It is as if two people were playing chess. At a certain point, one of the players rises from the table, leaving his opponent to ponder his next move. The opponent struggles with all the possibilities because he is determined to win. What he has not realized is that there are only a limited number of moves that he can make, and not one of them can change the outcome of the game. No matter what he does, he will lose.
Just so at the Cross, the outcome of the chess game between God and Satan was decided. God will certainly win. Satan, however, is presently playing out every conceivable option, imagining that somehow his rebellion will triumph. It will not. "
