I understand what you're saying, but I have to disagree. When Paul says he was the "chief" of sinners, he certainly did not mean he was the worst sinner ever. He tells us he was blameless under the law. Philippians 3:6
Paul is speaking of his being the first (for a pattern) of those who would be saved hereafter.
1 Tim. 1:9-16 Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, 10 For whoremongers, for them that defile themselves with mankind, for menstealers, for liars, for perjured persons, and if there be any other thing that is contrary to sound doctrine; 11 According to the glorious gospel of the blessed God, which was committed to my trust. 12 And I thank Christ Jesus our Lord, who hath enabled me, for that he counted me faithful, putting me into the ministry; 13 Who was before a blasphemer, and a persecutor, and injurious: but I obtained mercy, because I did it ignorantly in unbelief. 14 And the grace of our Lord was exceeding abundant with faith and love which is in Christ Jesus. 15 This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief. 16 Howbeit for this cause I obtained mercy, that in me first Jesus Christ might shew forth all longsuffering, for a pattern to them which should hereafter believe on him to life everlasting.
Paul was speaking as a man under the law in chapter 7. He was a man most wretched because the law had dominion over him. The struggle you speak of is what those who attempt to keep the law by their own efforts have to endure.
Romans 7
7 Know ye not, brethren, (for I speak to them that know the law,) how that the law hath dominion over a man as long as he liveth?
I say the same, Robert, believing, as Paul says, that we are
dead to sin. Sin really has
no more dominion over us. We have been delivered from the law, and satan has no room to accuse us of sin. EVER.
So, was Paul carnal and sold under sin after he was created IN CHRIST Jesus....a new creation? Of course not. He was NOT carnal. He goes on to tell us why.
Romans 8:6 For to be carnally minded is death; but to be spiritually minded is life and peace. 7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
