In times of special need and of the church's weakness, there is a biblical and historical warrant to resort to extraordinary prayer for revival… We must recognize, however, that prayer is a spiritual gift, something that cannot be created artificially or regimented. We are not to think that we can organize prayer as if we are in control. The very ability to pray with unction and faith is given by the Holy Spirit, and although that activity largely precedes revival, prayer also is an integral part of revival.
