Have you ever wondered why some things are done they way they have always been done?  It has been said that the definition of insanity is doing the same thing over and over again and expecting different results.  Could it be that this is what's happening with Sunday School?  What is Sunday School anyway?  Is there any real purpose to Sunday School, specifically in America?  What can churches learn from the history that keeps repeating itself as a result?  Am I in sin if I don't participate in Sunday School when my church offers it?
