I am curious to know whether or not God is marking Cain for protection or in shame, and what that mark may be. I suppose I just don't understand the basic point of the whole story. Cain's sacrifice was not taken because it was not a blood sacrifice, but I have heard that wheat sacrifice was considered just as worthy. Still, the Bible states that God did not find favor with Cain, as well as with his sacrifice. So he murdered Abel for jealousy? - posted: August 17 2005
