Not at all. Paul was not a philosopher. As a Jew he was very pragmatic in his descriptions. He in fact warned against vain philosophies. Rather he experienced the inner man/outer man duality in very real contrast....that's why he wrote what he did. Whether we will benefit from his admonitions and testimony really depends on what part of us is in control...the outer man...or the inner man.
I don't know where you are getting this jargon from. Maybe that is why I'm confused. Romans 6:6-7 talks about the old man (our sin nature) being crucified - making our nature dead to sin. The outer man is just a shell that has no need to be reborn until the resurrection at the second coming. It just keeps getting older and older until it dies. Sin is in our nature - the old man.
Romans 6:
knowing this, that our
old man was crucified with Him, that the body of sin might be done away with, that we should no longer be slaves of sin. 7 For he who has died has been freed from sin.
E, you really need to use biblical words for clarity. Otherwise it just becomes man-made philosophies. And, personally and frankly, I rarely agree with those.
One thing that Paul made clear is that we do not have two natures at the same time. We are either serving the devil, or Jesus. But never both. This is why it is important to not just have the fact that we are dead to sin when the old man dies, but we need to reckon ourselves dead to sin, because we still have freedom or choice.
10 For
the death that He died, He died to sin once for all; but
the life that He lives, He lives to God. 11
Likewise you also, reckon yourselves to be dead indeed to sin, but alive to God in Christ Jesus our Lord.
12 Therefore do not let sin reign in your mortal body, that you should obey it in its lusts. 13 And do not present your members
as instruments of unrighteousness to sin, but present yourselves to God as being alive from the dead, and your members
as instruments of righteousness to God. 14 For sin shall not have dominion over you, for you are not under law but under grace.
From Slaves of Sin to Slaves of God
15 What then? Shall we sin because we are not under law but under grace? Certainly not! 16 Do you not know that to whom you present yourselves slaves to obey, you are that one’s slaves whom you obey, whether of sin
leading to death, or of obedience
leading to righteousness?
