Is It Important to Have a Regular Corporate Prayer Meeting?

Josh Smith in Jasper, Alabama. How important is instituting a regular corporate prayer meeting versus just sort of a passing prayer on in your regular service times for what God wants to do? I think it's dangerous to start to try to establish a formula for revival. Sometimes among the best things you could do is get together and pray with your staff. It goes back to what is the spirit of God's thing to me. His thing was not meant to work without having an ear to hear.
