If in a leadership gathering, you rehearse your prayer before you speak the words, that rehearsal is not driven by your worship of God but by something else entirely. God hears the rehearsal! Such a prayer is not an act of worship but a means of aggrandizing yourself in the minds of those who will hear you pray. You want to appear humble, contrite, worshipful, grateful, and theologically informed, not to God but to the other people who are in the room.
