Rom 8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
My question is: How does God condemn sin in the flesh if there was no sin in the flesh of His son?
Sin is not imputed where there is no law. If one is not under law, then they are free from sin, since sin is not imputed, if there is no law.
As an example, marijuana laws are different in different states in the US. Marijuana is a sin in some states where there is a law, but if you cross the border to a state, where there is no law, there is no sin in that state. Law defines sin, and if the law is revoked, then the sin is also revoked.
Jesus was under faith instead of the law. Jesus was called a drunkard and glutton by the Pharisees. This may have been true, based on the laws of the Pharisees. But since Jesus was not under their laws, this same behavior, for him, was like him crossing the border, to another state, where this is legal. If you stood at the border between two states, where in one state marijuana was legal and the other state it is illegal, the people on each side will treat you differently in terms of your behavior. Only one side will see a sin.
The reaction will be more hostile, where there is law. Jesus crossed over the waters to a new state of mind, where nothing was unlawful, making him free from sin. God is not under man's law and sin.
Original sin is an artifact of social conformity to law. To use our example, in states that have strict marijuana laws, even if you would never thought about smoking, you are still required to be under the law. You are treated as a sinner, even if your nature as a person would not allow you to smoke, even if it was legal. Law and conformity to law assumes everyone is a potential sinner; Original sin, and forces conformity.
Original sin is not from God, but is manmade. It forces conformity to law, as though everyone can have a bad day and break the law. It assumes an inner criminal, in all, that can appear at any time. This is a time illusion created by law, since nobody can predict the future. Conformity to law, by everyone, is a solution to minimize the future criminal unknowns. But in doing so, it assumes original sin is part of all of us.
Jesus, as the son of God, was under faith. He lived in a state of mind, where all things were lawful. If all things are legal, nothing you can do, will generate sin. His behavior, may be look like sinning to others, who live in another states of mind; full of taboos and laws. Such people can resent someone, not under their law; original sin. They tried to force Jesus, to be be an original sinner and conform to their laws.
Jesus was the new Adam and was not part of original sin, since he was not under any law of man. As a last ditch effort to assert law and original sin over Jesus, they gave Jesus the death penalty, as though he was guilty of the worse sin the law had, env though he did nothing wrong. The death penalty assumed he had an inner sinner potential; original sin. But he was never under the law and sin is not imputed where there is no law.
