Study: Romans 12-13

One of the key disciplines of the the Christian life is study.  Spend an hour studying and really trying to get at the meaning of Romans chapters 12 and 13 (many scholars agree these passages are best read together).  What was Paul saying in this text and why was he saying it?  Consult commentaries, look up words you think are key in lexicons, go as deep as you can into the passage.  What do you find?
