Part 8:  Cain & Abel (Genesis 4)  Our story picks up outside of the Garden.  Cain & Abel offer sacrifices to God.  Turns out, some sacrifices are received and others are rejected.  One did right and the other, well something seems wrong with his attitude.  God intervenes and has an interesting conversation with Cain.  Ignoring God's warning, Cain does the unthinkable.
