Sorry, still don't understand. First, just to be clear (and I'm sure you know this), Paul didn't write the Bible, God did, each and every word. That notwithstanding, and just to level-set, would you mind restating your bottom-line point to tie it all together cause I've lost it?
No problem.
Paul, by the grace of God, wrote Rom 7 from two different perspectives.
The past of his life and the present life.
He used the present-historical tense, (also called present-narrative), to describe, (narrate), were he
was and what he thought while
still a man walking after the flesh.
Though he was now walking in the Spirit.
Anyway, a few questions:
Verse 18 doesn't sound like it pertains to the past to me: the "that in me" and "in my flesh" describes present.
Ask yourself...Was Paul still carnally minded after his conversion to Christianity?
NO!!!
He is stating a prior condition.
Verse 16 is based on Paul's condition during the time from whence he is narrating. ie...as verse 14 says..."For we know that the law is spiritual but I am carnal, sold under sin."
Paul is pointing out that though he wanted to keep the Law, he couldn't...as a man walking in the flesh instead of walking in the Spirit.
Again, 7:22 does not seem to reference the past as it is saying that he (in the present) "delights in the law of God"
[Rom 7:22 KJV] 22 For I delight in the law of God after the inward man:
Paul is pointing out that though he wanted to keep the Law, he couldn't...as a man walking in the flesh instead of walking in the Spirit.
Verses 23 and 24 conclude his lament...from his past.
Verse 25 wraps it up..."I thank God through Jesus Christ our Lord. (for delivery from "this body of death" in verse 24)...So then with the mind I myself serve the law of God; but with the flesh the law of sin."
Paul is no longer in the flesh, as he already referenced in verses 5 and 18.
He has separated one from the other.
The purpose of Romans 8 generally seems to be to explain to us what Christ alone achieved for us; that is, it ties it all back to Christ. I'm not exactly sure what you meant by "prevails with the new "Spiritual" mind"" -- if it is that a new spiritual mind (of itself) made anything to "prevail", I would have to disagree, as everything that is "new" spiritually, to include the mind, is given by/through Christ.
If you meant Romans 8 teaches that amongst the gifts of Christ, is also a new spiritual mind, I would definitely agree.
We might be saying the same things but I'm just unsure
Rom 8:5-13 are alternating (parts of) verses contrasting a walk in the flesh with a walk in the Spirit.
We can't walk in both.
However, Rom 8 contains much more than just that.
I seem to be having some computer problems, so if that wasn't clear, please ask again.
Sorry.
