You're just channeling the gnostic dualism that views everything as being determined by nature. The spirit man can't sin, but the old man can. Guess what? This dissociative separation only exists in the mind. Man is a whole comprised of old man and new spirit, and GOD holds the whole man accountable for what he does with the body.
The gnostics did not believe this. They believed that they were saved by their spiritual nature, just as you do; and that the conduct of the body was irrelevant to salvation, just as you do (and even said so in your post).
Budman: how we live our lives has no bearing on whether or not we keep our salvation ... We are holy, righteous, and sinless because that is what He is, and what His nature in us proclaims
Gnostics (per Irenaeus): [the gnostics] hold that they shall be entirely and undoubtedly saved, not by means of conduct, but because they are spiritual by nature... it is impossible that spiritual substance (by which they mean themselves) should ever come under the power of corruption [of sin], whatever the sort of actions in which they indulged.
How we live our lives has no bearing on how
we keep our salvation because WE don't keep our selves....
WE are Kept by GOD....that is part of the good news....
Saved by our Lord Jesus Christ,
kept by our Lord Jesus Christ.
How we live our lives BEFORE being saved
proved our need of a Saviour....
how we live our lives AFTER being saved
is part of, the sanctification process,
and though it may have a bearing on rewards,
it has no bearing on salvation, because who
The Lord saves, He keeps.
How you and the Lord
relate to each other is personal, but
He knows them that are His, and once you are a
son or daughter of the Living God, He promises
to never leave you or forsake you.....
He's not the kind of God who saves and then loses,
and He's not the kind of Father
who adopts and then rejects.
Praise the Lord, He loves us, He saved us,
He proved it.
That's Good news!
Our salvation is dependent upon our abiding in Christ where there is perfect safety.
Our salvation is DEPENDENT upon Jesus Christ
and His finished work upon the cross, and His
resurrection from the grave.
Salvation is by grace, through faith IN CHRIST,
not by our own efforts to abide. Again, the abiding
will follow salvation, that is sanctification.
The day I stop learning is the day I start to die, spiritually. Am I humble enough to be teachable? God, please help me to stay open to Your Truth. Am I willing to admit when I am wrong? God, save me from my ego, and the egos of those who refuse to admit to any fault. Am I loving? God, please keep me mindful of having a compassionate and contrite heart, for great is Your goodness, and we all fall short of Your Glory.
Ahem, Amen,

Love!
'And be ye kind to one another, tenderhearted,
forgiving one another, even as God
for Christ's sake has forgiven you.'
