Piper: "Very few people think that we are now in a war greater than World War II, and greater than any imaginable nuclear World War III. Or that Satan is a much worse enemy than Communism or militant Islam. Or that the conflict is not restricted to any one global theater, but is in every town and city in the world. Or that the casualties do not merely lose an arm or an eye or an earthly life, but lose everything, even their own soul and enter a hell of everlasting torment (Rev. 14:9-11).

Until people believe this, they will not pray as they ought. They will not even know what prayer is."
