Do you think G-d was surprised by their choices? That G-d didn't know until they did it?
God, as an omniscient being can know whatever he chooses to know, but because he made humans with free will (part of being made in God's image) he allowed them to make their own choices, each with a different outcome. Animals are governed largely by instinct, but humans have the same logic and reasoning capacity as their Creator. They can make decisions based on what they know to be right. There was only one negative command in Eden and no reason at all to transgress it.....until a third party with a wicked motive stepped into the picture and started asking the right questions....planting seeds of doubt.
There were several possible scenarios, so whatever they chose, God was ready with a solution.
Have you ever considered what would have happened if the woman had said no to the temptation? Or if Adam had refused his wife's offer? How do you think God would have responded then?
We believe that God's adversary was the voice behind the serpent (according to Christian scripture), so he targeted the woman when she was alone. As the younger and less experienced of the pair, he appealed to what appealed to him....self interest. In saying to the woman that eating the fruit would result in her 'being like God', he was actually voicing his own ambitions. He wanted to be a god to someone....and here were lower beings who could give him what he craved. She fell for his twisted reasoning, imagining that God had lied and was keeping something desirable away from them.
She obviously waited for the instant death that she may have expected but when it didn't happen, she offered some of the fruit to Adam when he returned.
Imagine what was running through his mind? What was he to do? He had waited so long for a mate and now he was faced with losing her. Did he know that death was not instant but a slow and painful decline into aging and sickness? We don't know. But the adversary knew he could possibly get to the man through the woman, so he did not target Adam first, (Adam would more than likely have resisted the offer) but he caused him to divide his loyalties. Divide and conquer has been the adversary's MO all along.
Christian scripture puts the blame for man's fall on Adam, not the woman. (Romans 5:12) As family head, it was his role to stick to God's law regardless of what family members decided to do with their own free will, and to keep his family in line. He failed in this respect and ultimately left his children a lasting legacy...an awful inheritance that no human could fix.....sin and all the things that result from it. Within one generation, a murderer was produced.
We have all been dying ever since, yet death is as foreign and unnatural to us now as it has always been. We were simply not created to experience it. God made the way for humanity to once again...live forever in paradise conditions on earth through the ultimate sacrifice of his son's life in exchange for ours. He is the appointed redeemer.
What is the Jewish expectation?
