Now see that's interesting I didn't know there were scriptures in the old testament that said that you cant die for someone elses sin which puts a whole new light on the Christian religion.
You really should read that whole chapter and not take someone's word based on two verses plucked out of context.
If your parents sin, they will die for their sins. You will not be killed for the sins of your parents. (That seems fair of God to me.)
If your children sin, they will die for their sins. You will not be killed for the sins of your children. (This also seems fair to me.)
If you sin, then neither your parents nor your children nor anyone else will be punished for your sins. You will be required to die for your own sins.
When we get to the NT, we get the bad news that ALL HAVE SINNED and therefore all shall die. Sorry, the percentage of people who deserve death is currently 100% under the Law.
If you are like me, then we are not even Jewish, so even the prescriptive sacrifices for sin are unavailable to us.
Since this is not about 'salvation' but 'atonement' I am under no pressing obligation to present the obvious Christian solution to this problem. However, all those verses say is a perfect man has nothing to fear from God, but a sinful man does.
That does not prove that Jesus could not have died for anyone's sins.
(You should really read it for yourself. Don't take my word for it.)
