'Life is war. That's not all it is. But it is always that. Our weakness in prayer is owing largely to our neglect of this truth. Prayer is primarily a wartime walkie-talkie for the mission of the church as it advances against the powers of darkness and unbelief. It is not surprising that prayer malfunctions when we try and make it a domestic intercom to call upstairs for more comforts for the den. God has given us prayer as a wartime walkie-talkie so that we can call headquarters for everything we need as the kingdom of God advances in the world.'
John Piper, Let The Nations Be Glad, p.65.
