The Bible tells us to pray for "kings, and for all that are in authority; that we may lead a quiet and peaceable life in all godliness and honesty" (I Timothy 2:2). To find out how your prayers can make a difference, and to better understand what really makes for a good leader, bring your questions to this chat with Christian Science practitioner and teacher Barbara Pettis. Ms. Pettis was previously involved with public schools and worked as a writer and editor. She has lived in Asia and in Europe and in many parts of the United States. She currently lives and teaches in the Boston area.
