My question, asked for more than 40 years of debating this with others, is simply how Paul can be a "captive" of the law of sin (7:23), and also "have been set free from sin" (6:22) at the same point of reference in present tense real time? I have yet to get a logically coherent answer from any one in that time span, and I don't think that I'm likely to in the future, simply because both statements cannot be true at the same time, and yet that is exactly what you want me to believe.
It is you who doesn't understand Scripture. Paul was clear about his own sinful nature, which he struggled with. And his admission to Timothy. You have no excuse for your unbiblical views.
And as for your "choices" argument, that is your death knell because Romans 6 and 8 both give the believer choice
There you go! Well, the Bible SHOWS the choices that all believers face. The Bible does NOT give believers the choice not to sin. That is faulty language.
Paul continues to refute your notions throughout his epistles.
Gal 5-
13 You, my brothers and sisters, were called to be free. But do not use your freedom to indulge the flesh ; rather, serve one another humbly in love.
15 If you bite and devour each other, watch out or you will be destroyed by each other.
16 So I say, walk by the Spirit, and you will not gratify the desires of the flesh.
Eph 4-
26 “In your anger do not sin” : Do not let the sun go down while you are still angry,
27 and do not give the devil a foothold.
30 And do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption.
31 Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice.
3 But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God’s holy people.
All of these verses are directed to believers. NONE of these verses make any sense IF believers do not have a sin nature.
Finally, consider Paul's prayer to believers:
Phil 1-
9 And this is my prayer: that your love may abound more and more in knowledge and depth of insight,
10 so that you may be able to discern what is best and may be pure and blameless for the day of Christ,
If your theory were correct, believers who cannot sin are already "pure and blameless".
esp if they no longer have a sin nature.
So Paul totally destroys your opinions.
