Piper on Prayer

I listened John Piper's message Prayer: The Work of Missions today, in it he says many absolutely class things about prayer. One statement that struck me about prayer was

"But what have millions of Christians done? They have stopped believing that we are in a war. No urgency, no watching, no vigilance, no strategic planning. Just easy peacetime and prosperity. And what did they do with the walkie-talkie? They tried to rig it up as an intercom in their cushy houses and cabins and boats and cars - not to call in fire power for conflict with a mortal enemy, but to ask the maid to bring another pillow to the den."
