For the next part of your response, I think you are not appreciating the purpose and meaning of the narrative. It is one thing to ask questions all day long about any given story, but in the end, every answer is nothing but a speculation. Answering questions that the narrative never intended to answer is a form of “epigesis” that leads one to put into the narrative that which was never intended to be put in it. We could ask questions about what the narrative could have been till we are blue in the face and still learn nothing and gain no knowledge nor improve our understanding of what the narrative is intending to offer on its own accord. So, please do be careful with how you treat the narrative. We must always seek to answer the questions about what the author was intending to do in relating the information that he or she provided. All else is vanity.
While you may not accept the story as a reporting of events which occurred in the past, it is clear that the author intended it to be just that. So, no matter what you or I believe regarding its nature as a factual report of events that did indeed occur is of no relevance. What matters is that the author is revealing to us an event that was shown to him in a very particular manner for a very particular reason in order to tell us a very important thing. Anything beyond that is fruitless and just us trying to read our own opinion, unjustified as it is, into the authors work. A mightily disrespectful thing to do to any author, and the first step away from actual exegetical study of a literary work.
Now, with regards to it being a “heaven on earth,” it was certainly not. It was the creation as God intended it to be, and as it was, was “very good” in God’s eyes. This is God revealing something of His work to humanity. If He was attempting to convey to us that this garden of eden was heaven, he would have called it heaven. No, this is nothing more than a setup that he intended at the beginning in order to accomplish something. He does not reveal to us what that intention was, nor has he a need to. At the time of his revelation of this to Moses, God had a very particular purpose in mind in conveying this information to the Israelite people. That is what I am attempting to guide my readers through in this series.
The Fall was neither a good thing or a bad thing. It is not a thing that is capable of having such attributes, and the text shows to us nothing regarding whether it was good or bad. That really has no point or purpose in the grand scheme of things. It is simply the way it happened according to the text. To suggest that the fall was a good thing or a bad thing would be nothing more than an effort to fruitlessly apply a moral quality to an object which has no moral qualities.
There is also more to the story than just the fall, which is why I am doing this series as well, and you will come to see some more points that might help clarify some things for you as I go through the series.
Now allow me to move to evaluating what you have written. Who is to say that you and I would not exist had it not been for the fall? Who are we to think we would know what the difference would be? Who are we to think we know the will of God during this situation? Also, you do not understand yet, but heaven is not for us to choose. It is an inevitable outcome and is not the objective of anything, nor is it the objective of the Judeo-Christian system of beliefs. It is just what has been revealed to us as something that is yet to come, and our living till the day it comes is something we are just in hoping for.
The fall is not responsible for anything. Adam and Eve had occur to them something that is unique to them, and that was a singular event in the course of human history. So much of what you have written in your response is grounded squarely in the assertion that the world would be different had this event not occurred. That my good friend, is pure speculation. Now then…I am off to playing with my children before going to night classes! As always, I enjoy the discussion and responses, sir. God be with you.
