They would have lived happily and multiplied, just as God commanded them I suppose. [though I am not sure where all the people would have lived on this planet if everyone who was ever born was still alive and multiplying! The Bible doesn't address that..."minor" point]
Would the serpent have slithered away, defeated, never to return?
Evil "exists" only as long as there is potential for sin. That, of course, is intrinsic in free will. By giving us freedom God also permitted evil. That freedom is necessary for us to love God by choice, otherwise it's not love.
Since we know for a fact that they DID have the potential to sin, unlike Christ
Christ's human nature was no different than Adam's, so it too had to have a potential to sin.
they would have cracked after some amount of time.
Speculation.
We know this was by God's design since He could have easily protected them from that potential.
Wrong. In order to be free, one must allow that potential.
So, everything happened exactly as God ordained it.
Everything happened as God knew it would, based on their free choice, by His permission.
Adam and Eve simply didn't have the tools to know what to do here.
Of course they did. They could have repented. The act that sealed their fall was their refusal to repent when caught. Adam blamed God for giving him "that woman" and Eve blamed the serpent. All they had to do was repent. God gave them ample opportunity to do so.
This is very different from God "inserting" evil into anyone, but it also shows that God's intent was that the Fall happen.
If God created Eve "ditzy" enough as you say to be easy pray then God set her up. It's no different than leading a child consciously to step into the traffic and then blame the child for getting hit. God gave her freedom to choose and she abused it. That's why we have lawyers.
They would have lived happily and multiplied, just as God commanded them I suppose [in perpetuity, with no one ever physically dying].
So, then would you say that it didn't really matter to God which outcome happened, and that either could have? God just sat back and watched? I would have answered the same question by noting that it was moot because it didn't happen. What did happen was what God wanted to happen, so that is what happened. Perhaps this is a good illustration of our differing views on the level of God's control in our world.
Christ's human nature was no different than Adam's, so it too had to have a potential to sin.
I disagree because my view on this is IMPECCABLE, Jesus could not have sinned (nyuk, nyuk :). While both Adam and Jesus did not have the sin nature, Adam had only one nature and Jesus had two. Were those natures wholly separate in every respect, or were they separate, but did support each other? Was Jesus one person or two? He was one, so the natures, while not "mixing" worked together.
Besides, if Jesus could have sinned then, then He could also sin now. What is different about His essence today vs. back then? Nothing. (Col. 2:9 : For in Christ all the fullness of the Deity lives in bodily form.) Christ is still the God-man today. But we would say if Christ sinned today it would violate His nature, so it is impossible. I wouldn't expect anyone to argue that Christ could privately use only His human nature in Heaven today to sin, so likewise He couldn't have while walking the earth.
Wrong. In order to be free, one must allow that potential.
So, for Adam and Eve to be free, God was obligated to let the serpent into the garden? OK, what about all the time in between creation and when the serpent came? Were Adam and Eve NOT free then? Were they not created free, IOW? If you say that the serpent was always free to enter, but just decided to wait, then you bely everything we know about satan and how he operates. Does he EVER just leave us believers alone? No, it is a constant attack. That scenario wouldn't fit. The serpent would have entered to hurt God and His people at the first opportunity.
They could have repented. The act that sealed their fall was their refusal to repent when caught.
I still don't get where you get this two-step process from. Apparently, you are saying that a real sin is the initial commission PLUS a failure to repent. The Bible doesn't say that. The Bible says that just sin equals death. When you ask your priest for forgiveness, and get it, do you then say to yourself: "well then I never committed that sin"? I HOPE not. :) But this is what you are saying when you say that the failure to repent "sealed" the Fall. The Fall was over and complete when Adam blew it, whether he repented right after or not. There MUST be sin before repentance even enters the picture. ....... Don't we all agree that at SOME later point Adam DID repent?
If God created Eve "ditzy" enough as you say to be easy pray then God set her up.
In a matter of speaking, YES! :) We know for sure that God, by instruction, BANNED them from the knowledge of good and evil. So, what chance did she have against real evil? I imagine she was a very trusting sort, and why not? She had never been lied to before, and couldn't possibly discern the difference. This was all by God's design.
It's no different than leading a child consciously to step into the traffic and then blame the child for getting hit.
That doesn't work unless you have the power to bring the child back to life. I'm not positive, but I assume Eve is in Heaven today. So, it's not the same. It also doesn't work because God did not coach (lead) Eve into blowing it. He did allow the traffic, but He didn't send her into it.
God gave her freedom to choose and she abused it. That's why we have lawyers.
Yeah, yeah, yeah. :)
