The paragraph that struck me?
When we fully understand that we are in a spiritual battle, that the world is not our home, just a "stopping off" place, we can begin to get excited about having a short time to engage in the battle raging around us. The Enemy wants us to waste our time generating anger toward others, ruminating over personal betrayals and over injustices due to sickness, accidents, and evil. He wants to destroy our ability to function productively and to disengage us from inspiring others to be Christ-followers. He wants us to give up and die or to control everything around us in such a tight-fisted manner that we're tied up in ridiculous knots.
