Great Sermon! Good stuff! I've pondered whether the separation of light and darkness represented the fall of satan, and if God allows man to eat of all trees, then (after fall of satan) changes it to only the tree of life, not allowing them to eat from the tree of knowledge of good and evil?? He gives them their first command, knowing their first temptation (from satan) is coming. Free will and the test of obedience(faithfulness)..God always provides a way of escape..
