Whether I find it circular or not is really not the point, BHS. Paul hammers this home in most of the letters to the nascent congregations, many made up of Jewish Christians steeped in the legalism of first century Judaism. That there is nothing we can do to appease God - sacrifices, pennance, out the window, must have come as a revelation to them - an entirely new way of thinking. Grace is a topic which could stretch to a hundred posts. It's amazing. (Sorry......)
