I have talked to other theologians on similar.
Eden was to have them appreciate what God can deliver.
Non-Eden was for them to understand what happens if one does not obey God's word.
Human equivalent to Heaven vs Hell
I would like to offer a more general answer that gets, I think, more precisely to the question.
The question of 'why does God allow evil', the fundamental question underlying the costs born by Man-kind for original sin, has been a problem since Epicurus said:
Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not willing? Then he is malevolent. Is he both able and willing? Then whence cometh evil? Is he neither able nor willing? Then why call him God?
Is God willing to prevent evil but not able?Then he is not omnipotent.
God is omnipotent but boundedly so in the sense that any omnipotent being will be bound by this: "Plan is identical to reality for an omnipotent being."- Cerpin Tax
God is willing to prevent sin and not able to end it without there being other consequences. If the meaning of reality is to bring you, you the person reading this right now, to this very moment: then every bit of evil would have had to have gone throughout the world otherwise exactly, precisely, who everyone is or has been could never be.
Paul calls this the evil of our world 'birthing pains' of the world to come.
Implicit in this is that God is a being of pure will, and to plan to make us, you and me dear reader, just as we are God had to go through with creating the evils that would lead us to be who we are.
Is he able, but not willing? Then he is malevolent.
So, God, if defined as good and defined as creator, must have created evil by allowing for evil to enter into the picture. Further God must have known the consequences of evil. Finally, God could eliminate those consequences, but one of said consequences is
precisely who you and I are.
Which is malevolence: to eliminate the good in you and I because there is some evil, or to allow for evil so long as there is still some good to be found?
Is he both able and willing? Then whence cometh evil?
I posit that it may come from a desire to have exactly who you are exist.
And to that cosmic setup of history and time and matter that has lead God to allow you to be exactly to you are.
I can't then believe in eternal punishment for you being who you are; but rather believe that God is in all that are loving, who act in a way contrary to self-serving lust and greed: particularly at their own expense.
In my experience faith in Christ directly is submission of self which allows for elevation by God; and I welcome anyone else, spiritual or otherwise, who might offer their own experiences and interpretations.
