Prayer is a war-time walkie-talkie, not a domestic intercom for ringing up the butler to change the thermostat. It is a war-time walkie-talkie to call in firepower because the enemy is greater than we are. If you try to turn this into a domestic intercom to bring another pillow, it malfunctions, and you wonder why. Its not made to be an intercom. Its made to be a war-time walkie-talkie. – John Piper
