God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
It is the voice of Christ that wakens the dead soul. Jesus speaks through the Bible, through ministers, through providences. His voice can reach the dead. He quickeneth whom He will. They that hear, live.
Revival describes a renewal of spiritual life, while reformation describes a renewal of the forms and structures of society and culture. It is not possible to have true reformation without first having true revival. The renewal of spiritual life under the power of the Holy Spirit is a necessary condition for reformation but not a sufficient condition for it. Therefore, though it is not possible to have reformation without revival, it is possible to have revival without reformation.
