Let's back up a bit. Creation is true and when God created Adam from the earth he breathed life into him. Adam at that point was perfect without sin. Then God created Eve. Both were perfect and sinless, and they had fellowship with God.
Then the serpent came tempted Eve and the rest is history. How can we blame God for that?
How can you not, after all he's the parent. My son is likewise perfect and without sin. He's too young to understand the difference between good and bad. Now I know that there are some christians who would say that my son is an unsaved sinner who if he dies tommorrow will burn for eternity for all his sins. However, I will assume that you are not so inclined, and prepared to accept that the innocence of a child is a close analogy to the state of grace Adam and Eve enjoyed in that creation myth you hold to be true. In this analogy his Mother and I play the role of God. We are almighty and with wisdom far beyond his ken. We need an analogy for the tree of knowledge. This shall be the cleaning cupboard. It's contents could well be calamatous for my little boy. If he consumes of the fruit of the cleaning cupboard then he shall surely die.
Here's where God and I differ. God simply told Adam not to eat the fruit. I've told my little creation not to even play with the contents of the cupboard he knows what's in there from when he sees the stuff in use. I wouldn't even mention the possibility of drinking the stuff or showing him how to open the childproof top, but I've also I told not to even open the cupboard. I've ringfenced the danger. I'm not omniscient but if I happend to be watching whilst he disobeyed either rule I'd intervene immediately before any harm was done. I've also got a lock for the cabinet.
I don't count myself as extraordinariliy wise, certainly not omniscient but I do know that there's a risk here and how to mitigate it. This God being is supposed to be omnipresent, omniscient and omnibenevolent, watching over us at all times and looking out for us and yet performs worse than me in this respect. How can you say he is blameless. Surely if I watched over my son as he disobeyed my rules in a manner I could have easily have prevented either before or during the event, such that he irreparably harmed himself in the process, you'd be holding me accountable for extreme negligence. Negligent for not placing additional barriers in the way of harm and negligent for not intervening as it became clear what was about to happen. He sets himself up to fail and doesn't even notice what's happened until later. He's can't even find Adam and Eve when he's walking in the cool of the Garden, and even though that's not the behaviour of an omniscient, omnipresent, omnibenevolent god it's still as negligent as if my kid had got into the bleach whilst I wasn't watching because I hadn't taken enough precautions.
It seems to me that you have a very low opinion of God to think that events unfurled in the way that they did without it being either his express intention or at the very least something he franklly couldn't care less about.
And if you were Eve do you think you would have been so rebellious?
Someone tells me not to eat fruit, someone else tells me I should eat it. I'm without knowledge of good and bad. I'm not sure, God knows what I'd do. (pun intended)
At that moment when Adam and Eve sinned they lost the garden and their fellowship with God because he cannot even look upon sin.
Horray look at me, I can do something that an omnipotent being can't.
If you were Holy you would understand better but without Christ's holiness in you it is still hard to come to terms with. I see it pretty clearly because I have some insight to holiness through Christ.
I would contend that we're the ones who understand this better, more holiness merely supresses doubts rather than answers them. If you can't see the flaws in this story of yours it's are you sure it's because you have greater understanding or could it be that you've blinded yourself to them. I suggest you pray for clear answers to these questions.
So now what? Wages of sin is death and cursed is the ground because of Adam and Eves origanl sin. In the beginning the world was perfect but after the fall everything was cursed. It is what he had to do being God is Holy. It's sin that caused all the problems, can't you see? It was always meant to be perfect even though God knew what he would have to do to redeem it. The good news is he will make it all new again and I think we would all not want to miss that opportunity.
Taking his sweet time over it isn't he? Sounds a bit like a Microsoft production schedule. 7 days to cobble the whole thing together. Then 4,000 years before the first service pack and 2,000 years later it still doesn't work as intended.
