You do understand that the 'serpent' was not an actual snake, but was a representation of what was 'within' mankind?
Take any human, and tell them they cannot do something. See what happens.
Oh. I understand now, I think? Sort of like how the 'days' in Genesis are not really our 24 hour days. Thank you.
So, when God had the snake slither away forever to eat dust, God was throwing evil out from 'within' man?
