My pastor does not pound the podium but one of his three translators standing next to him does -- many times in a sermon he's interpreting. For those of you that are preachers -- do you have this habit ? Perhaps you are not aware of it even if you do it . Maybe some preachers want to emphasize a point strongly and feel their words are not as persuasive as they would like . Therefore , down goes he fist . But then again John Knox , the ardent Reformer , who was as convincing as they come , would have knocked his pulpit to smithereens even in his last days .
