Im not sure I understand you, but man by nature is dead to God, he can do nothing Godward worth anything towards Salvation, he must be born again, resurrected from the dead, which is totally out of our control.
in nature man still has nature that is of God, this is his human nature.
Which was spiritualy alive before the fall. Or call it born again.
Because when ye are born again ye are made spiritualy alive
Which means the human nature you have is cleansed of spiritual death, that your human nature was experiencing whilst unsaved.
Your human nature is still alive to God but the spiritual nature of human nature is alive to death.
This is why ye must be born again..
What your not understanding to be born again means you where already born once with spirit.
Spirit does not die.
What happens is spirit become controlled by death ie Adam.
This is why ye are sown perishable
