dear Terry...
you said: "Was the tree a MORAL tree? Creator God had pronounced it "Good"."
the creation was pronounced good and then God warned about THAT tree...if it was still "good" then there wouldn't have been a need to warn against it, now would there?
you said: "So how is it this strange little invention, man, can piss God off by performing according to its own nature?"...
I'm sure that God sent His Son because He cared for mankind and there was no other way out of the predicament that he had gotten himself into.
you asked: "Doesn't the above heartwarming story indicate "experiential knowledge" BEFORE being expelled?"...
no, it indicates, as I've said before...some realisation of his fall from grace. he knew he was no longer "covered"...he hadn't experienced WHAT no longer being covered was. As that experience was realised outside the garden...where the toil and pain is.
love michelle
