How about you actually attempt to deal with the FACT that Jesus crucifixion is JUST AS the raising up of the bronze serpent - where not a single Israelite that was bitten was without access to the cure. They could, all of them, look to the serpent. Whether they looked or not, the cure was there for them.
Bitten Israelites translate to sinning humans...the source of the analogy points to the target of the analogy - that's how analogies work.
What if the perception is all wrong? What if Jesus didn't die for people, but for the sin OF the people?
What if Jesus died for the snake-bitten condition rather than the peoople themselves?
He was the scapegoat, who was made sin (not singular articular, but singular anarthrous). The scapegoat didn't have people placed upon it.
He didn't die for the whole world. He died for the SINS of the whole world. And sin is not a "something". It's a lack of something as a "somethinglessness".
He died for the hole or void in mankind. To fill it by being made sin, the singular anarthrous noun. The source of all acting and actions as the verb.
What if everyone is squabbling over the wrong thing? Focusing on the whos rather than the what.
