A slight correction here.
Jesus was not sacrificed on the cross to save sin prone nature, he was placed up there to destroy it...that's the point being made - it couldn't be saved or fixed, "flesh and blood" was under condemnation and the only way to remove that death was to destroy its power (the wages of sin is death) hence a sinless sacrifice was required to uphold the righteousness of God.
Now Romans 8:1-3 applies to those found in Christ - meaning they are in His raised glorious body which is no longer flesh and blood held by the power of death (i.e. Devil)
He is a Spirit being, we are being fashioned into his image and after his likeness as he is of God and the Elohim.

You misunderstood my use of the word 'save'. I used it as 'except', not 'deliverance'.
See, we are getting closer now to your focus on angels.
But angels are not really the topic of thread. So start another topic or go back to your previous one.
