This is plainly untrue in those verses,
the flesh did reign:
We know that the law is spiritual; but I am unspiritual,
sold as a slave to sin. [SUP]
15 [/SUP]I do not understand what I do.
For what I want to do I do not do, but what I hate I do. [SUP]
16 [/SUP]And if I do what I do not want to do, I agree that the law is good. [SUP]
17 [/SUP]
As it is, it is no longer I myself who do it, but it is sin living in me. [SUP]
18 [/SUP]For I know that good itself does not dwell in me, that is, in my sinful nature.[SUP]
[c][/SUP]
For I have the desire to do what is good, but I cannot carry it out. [SUP]
19 [/SUP]
For I do not do the good I want to do, but the evil I do not want to do—this I keep on doing. [SUP]
20 [/SUP]Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it.[SUP]
21 [/SUP]So I find this law at work: Although I want to do good, evil is right there with me. [SUP]
22 [/SUP]For in my inner being I delight in God’s law; [SUP]
23 [/SUP]
but I see another law at work in me, waging war against the law of my mind and making me a prisoner of the law of sin at work within me. [SUP]
24 [/SUP]What a wretched man I am! Who will rescue me from this body that is subject to death? [SUP]
25 [/SUP]Thanks be to God, who delivers me through Jesus Christ our Lord!
So then, I myself in my mind am a slave to God’s law, but in my sinful nature[SUP]
[d][/SUP] a slave to the law of sin.
So how did the flesh not reign in the above? The flesh won every time, it dominated Paul, he was its slave
