Most prayer in the Book of Acts was corporate prayer. The Apostles had two main responsibilities: leading the church in prayer and ministering the Word (Acts 6:4). Serving tables and the like were handed over to Spirit-filled men so the shepherds could oversee the prayer ministry in the church. Is it not instructive that shepherding in prayer is mentioned prior to the important task of preaching? This order is not a trivial fact, but quite instructive. But what other factors contributed to such powerful prayer?
