John Piper

Probably the number one reason why prayer malfunctions in the hands of believers is that we try to turn a wartime walkie-talkie into a domestic intercom. Until you know that life is war you cannot know what prayer is for. Prayer is for the accomplishment of a wartime mission…But what have millions of Christians done? We have stopped believing that we are in a war. No urgency, no watching, no vigilance. No strategic planning. Just easy peace and prosperity. And what did we do with the walkie talkie? We tried to rig it up as an intercom in our houses and cabins and boats and car – not to call in fire power for conflict with a moral enemy, but to ask for more comforts in the den.
