Magnum, the NT is about a group of people who believed in one of the Jewish Messiahs, the one that was crucified by the Romans. Perhaps they all were, we don't know do we. So after the fact they had to explain why their leader died. Enter the Ransom Sacrifice doctrine. He was meant to die, he did not fail.
Aligned with that goes the idea that we are all sinful, missing the mark. Falling short of the glory of god. No more super heroes. No more Davids, Samsons, Solomons. Just weak people who need a saviour. I prefer pagan religions to this sad story of the fall I must say.
