Man has always had free will. The Garden of Eden is the story of when he first used it. I don't know if it's literal or not. I expect not but it doesn't matter at all because it's just a way for human minds to grasp an idea anyway.
I appreciate your insight on these type of threads quite a bit. Regarding the 6 day creation narrative in Genesis, or Noah and the Ark, or Jonah and the great fish (for examples)…what are your thoughts regarding whether they were literal or not…?
I don't think it matters whether they are literal or not. It doesn't mean they aren't God's word. These stories are meant to teach a lesson or make a point. They aren't meant to be perfectly accurate historical accounts.
