My feeling is, the Course is getting better and better with time. Not just for me through the deepening of my understanding over the years. No, it seems that it actually developed further, while Jesus was dictating it. Thats pretty common with every book, just with this one its surprising, since it came from out of time. Maybe it was the first book Jesus wrote and so he had to get into it :) Anyway, I just love those later chapters and chapter 18 is really one of the best so far for me.
