There is the old saying “When in Rome.” The idea of course is that if you are a particular area or with a group of people you act like they do. If you are with a sophisticated people you act sophisticated. If you are Red Necks you act like a Red Neck. If you are among Pagans then act like one. Whatever you do don’t stand out. From the world’s way of thinking that is how you succeed.
Of course it is those who stand out who are successful. But really the saying should bother us because it is wicked. That way of thinking is opposed to Christ. In a human way of thinking conforming gets you noticed, liked, and it opens doors.
