I see the spiritual warfare we're engaged in as a tug-of-war between God and Satan with us choosing the side we want to be on. If you choose right, there will be two winners and one loser; and if you choose wrongly, there will be one winner and two losers. (Note that if God wins, you win, and if he loses, you lose; while if Satan wins, you lose, and if he loses, you win ~ all this showing that God is always with us and Satan, always against us.) This contest exists only because we haven't made our choices yet ~ much like the undecided voters being sought after in an election. The smart thing to do is to choose God and stick with him at the outset, then there won't be any tug-of-war to be concerned about. When you are safe with God, as in union, you are beyond Satan's reach.
