We typically put a speaker's stand with a microphone at the front of the auditorium, floor level, facing the platform. People are instructed to move to the microphone and speak clearly into it as they are led to pray. They may lay their Bible on the stand to read a passage of Scripture if they wish. It confronts you with the dignity, power, and potential of the Word and brings focus in the midst of prayer. Beware, however, of reading long passages, which more often results in boredom.
Nothing can kill enthusiasm for prayer more quickly.
A sovereign empowerment of the Holy Spirit comes upon those who are led to pray. Instruct pray-ers to wait for a specific prompting of the Holy Spirit before they move forward to pray. They should know precisely what they are going to pray about. In larger corporate prayer settings where someone is already at the microphone, those who have been led to pray can be seated on the front row and wait for their turn. Once they've prayed aloud, they can return to their seat to continue to pray in agreement.
