This topic certainly deserves the flaming folder next to it.
Here's my 2 cent theological exposition:
When the original pair sinned, they broke a mystical connection they had between themselves and God. That's why they slowly died, diconnected from their life source. None of the children they had were born with this connection, so all slowly die. However - Jesus was sent and through God';s power was born with this connection - a connection that had to be withdrawn during his final hours for him to die; hence his cry, "Father, why have you forsaken me?"
Now, to restore that connection for imperfect creatures like us, who did not ask to be born this way and thus can be shown mercy, someone has to fix it. Jesus has been given the power and opportunity to fix it, and "he has learned obedience through the things he has suffered." His mission here was as much for him to learn about being human, as it was for us to learn about being divine. He knows our pain, confusion, spiritual agonies. He has eaten, drank, been thirsty and confused and tempted, has shit and been in love - he knows it all. So he has been fully trained in HOW TO BE WILLING TO SHOW MERCY.
The actual mechanics of fixing that connection are beyond our comprehension. However, his death was necessary, because he had the RIGHT to live forever as an imperfect human. But metaphorically, he said, "If Czar messes up, I'll die for him." Well, guess what, I messed up and Jesus had to accept that penalty 2000 years ago. And he's done it for each individual that agrees to accept it.
Having undergone that, he was restored to life, which God can do at will. Remember, this ransom is only part of God's plan - which is to fill the earth with the perfect seed of Adam. Having forever given up a human life, Jesus is now our Kiing in charge, temporarily, of bringing us all closer to god. It's a long and difficult journey, but he is now much more merciful than he was when he was leading the Israelites through their wilderness, having tasted the bitter fruits of imperfection.
The original story of the fruit may only be a metaphor, or it might be literal. When you're rebelling against god, one action is as good as another.
But I sense a great deal of contempt in this forum, so I will shut up now, having said my piece.
