Did any of the Angels sinned without the flesh ?
So I am sure the answer is yes.
So its not the flesh that is sin its the what in the heart that come out of the man that corrupts him.
Matthew 15:18
18 But those things which proceed out of the mouth come forth from the heart; and they defile the man.
If sin is the flesh, Mary gave Jesus his sinful flesh.
Now I know this doesn't go to well with some. But he was a seed of Abraham and David as the scripts says.
Our flesh is just a house that the heart(soul) reside in, we will get a new body in heaven if our heart is pure.
No, our flesh is responsible for the majority of our lusts to sin. God made it so, otherwise we wouldn't need His Son to come in the form of flesh as us, and be without sin, and die for us on the cross to defeat both death and sin. So really our thinking should be flesh = death. And thus Apostle Paul showed this distinction in 1 Corinthians 15 with the difference between the flesh vs. the spiritual body.
And as I said again and again, but some people only hear what they want to hear, Apostle John defined sin as the transgression of the law. And that's how it was that the devil sinned in the beginning prior to Adam and Eve in the flesh. Thus this flesh world was created 'in bondage' waiting for release when the sons of God are manifested (Romans 8). Paul was speaking that release from bondage about the glory of the world to come, not about this present world.
In Romans 8, Paul showed that God placed this present world in bondage to corruption, waiting in hope along with us for Christ's Salvation in the world to come. That is why flesh is of this present world, not of the world to come. Flesh represents this imperfect world; it represents corruption, imperfection. That is why Apostle Paul said flesh and blood cannot inherit the kingdom of God, neither does corruption inherit incorruption.
The type body of the world to come is a "spiritual body", a body of incorruption. That is what Paul taught in 1 Corinthians 15, which Chapter every Christian should make an in-depth study of.
One of the MAJOR deceptions of this present world, is the false idea of salvation in the flesh, which is a doctrine from the children of darkness. They actually believe that flesh man can become... perfect in the flesh, becoming your own god in the flesh (yes, they actually believe they can become their own god. Afterall, that was the serpent's original temptation against Adam and Eve). That is why they don't want to believe that flesh = corruption and is not what is saved in Christ's Salvation.
