The Book of Acts contains as least 30 references to prayer in many settings. The local church rises or falls with its praying. If you ask the average  member, he will say, “No, the church rises or falls with its preaching.” Preaching is important. But praying was behind the apostles preaching in the Book of Acts. You’ll find that the Apostle Paul was a man of prayer. Peter was a man of prayer. The early church believed in prayer. The local church and its ministry will rise or fall with its prayer life.
