When members of the early church cried out to God in urgent need, the place shook with the power of their supplication. In this compelling vision for modern-day supplication, Bill Gothard recognizes the key truth that only God's almighty power can rescue His children in times of distress. Using illustrations from Scripture and testimonies from everyday people, Gothard demonstrates the power of crying out -- and how God can shake the world of those who cry out to Him today.
