And this is where you miss it.
The Denying Duo has been shown time and again, but, like insolent children, demand that the arguments conform to their verbatims. God is not inclined to acquiessce to childishness. So let's put the maxims to which they pay lip service to the test.
1. What does it mean to be made sin?
2. What does it mean to bear our sins?
3. What does it mean to be made a curse?
I will simply take the third case, because the Apostle lays out the argument for us, linking us right back to the law upon which His statement is based, and because Jon supplied a retort to the Apostle's case very useful in the undoing his own premises.
Paul said, and I agree with him, that
Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree: Galatians 3:13
As is common among the NT writers, Paul did not quote the law verbatim, but drew from it the obvious implication. The writing to which Paul appealed is thus:
And if a man have committed a sin worthy of death, and he be to be put to death, and thou hang him on a tree: His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; for he that is hanged is accursed of God; that thy land be not defiled, which the LORD thy God giveth thee for an inheritance. Deuteronomy 21:22-23
In retort, Jon said this:
So your interpretation of the passage is anybody who is hanged on a tree is cursed by God (like Peter, Black people who were lynched, the Hebrews who were crucified by the Saducces during the Hasmonean period, etc.)?
Isn't that a little like witchcraft (if you want to have somebody cursed by God, hang them on a tree)?
The retort is a ridiculous, obviously, and a DIStortion of the argument. Of course the mere hanging on a tree does not result in a curse. It is the guilt of the one hung, and the just sentence on that one for his sin that results in a curse.
When Paul said that Jesus became a curse for us, it means that He took our place in judgment. He took our sentence. It is really that simple.
