Your suggestion is misplaced.If you believe that He bore our sins in his own body, and that the actual reason he suffered and died was for our transgressions, and that God set him forth as a propitiation in His blood; well, the only thing I would suggest is that you look to see if scripture shows that sin can cause a reaction from God that humanly is described as "wrath" in English. Because then, if he bore our sins, he bore God's wrath. It's not really a stretch. Do I think that God the Father was ever personally angry with Jesus? I don't, apologies to R.C. Sproul. But this plan of redemption involves these things. It is plain to see. And we are looking into something we should be careful messing with. We do know God's view of sin. We do know we are children of wrath until we are saved.
We are told directly that "he that believeth not the Son shall not see life but the wrath of God abideth on him". Now, am I going too far in interpreting scripture directly if I say that I am going to assume that, since this is only 22 verses beyond John 3:14, where the Son as the one being lifted up like the serpent in the wilderness is the one you are to believe in - that is is something in that that solves the problem of God's wrath? You should be careful because if you say no, it's your faith then the question is faith in what. That the events happened? Why are you so adamant that this connection cannot be made when John clearly made it? And from other things you say, are you trying to take John 3 and start with "you must be born again" and then somehow cut out verses 14-16 or act like anyone who sees them is a heretic?
No. The truth is, you must be born again. And this is taught along with the idea that Christ gave himself for us on the cross and to reject that will cause the wrath of God to abide on you. That is clear in John 3 as far as where the look of faith is to be directed. And so I am going to make a big heretical assumption. That is that the wrath of God was abiding on us who now believe and what we believe involves Jesus getting that removed on the cross - as scripture says.
Yes, God's wrath is against the wicked. Yes, sins are the "fruits" of a mind set on the fkesh, what wickedness produces.
But I suggest you look in the Bible and read how God forgives. This is very different from what you suggest.
And I agree that we currently sin and fall short of God's glory in the flesh. When we do sin we have an Advocate in Christ, and Mediator who as our High Priest makes propitiation for us.
I disagree that this is because God punished Jesus for our sins.
Instead I believe that our flesh dies because of our sin and live because of righteousness. I believe Christ Himself is the Propitiation.
But I also believe that our sins are propitiated rather than punished on another.
