Why does the Lord want believers to pray together? Is this a biblical duty or is it optional? What difference does it make if we pray privately or in company? Is it possible for a dwindling prayer meeting to ruin the work of a church? What format should a prayer meeting ideally take? And what should be the style and content of prayer? Dr. Masters answers these and many other questions in this booklet. He shows that corporate prayer in prayer meetings was ordained by Christ and given a unique promise of effectiveness. The early church (in Acts) obeyed, and God's power came down upon their witness.
