When people are praying 'round the circle', each one taking his turn, their prayers in tongues—as when they pray in natural language—tend to be of the same duration, as if they had all agreed to divide the total amount of time devoted to prayer equally. Public messages never seem to be as long as sermons or testimonies, but they have their own common duration .... Since a message is given with the conviction that it contains important in formation from God, the speech is faster (perhaps because the message is urgent) and the volume greater.
