I acknowledge that Romans was written after Paul's conversion but in Romans chapter 7, he was talking about how he was BEFORE his conversion as being under the law for how that was like as a sinner.@JesusIs4Me,
For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
If then I do that which I would not, I consent unto the law that it is good.
Now then it is no more I that do it, but sin that dwelleth in me.
This is after Paul's conversions. Paul didn't understand Satan tempting him until after He was born again. Paul said, it not him that's making himself feel the way he does, but Satan (who is sin) causing him the problems. Paul could not understand this except by Christ's teaching after his conversion; not before.
Romans 7:1Know 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? ....5 For when we were in the flesh, the motions of sins, which were by the law, did work in our members to bring forth fruit unto death. 6 But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter....14 For we know that the law is spiritual: but I am carnal, sold under sin. 15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I. 16 If then I do that which I would not, I consent unto the law that it is good. 17 Now then it is no more I that do it, but sin that dwelleth in me. 18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not. 19 For the good that I would I do not: but the evil which I would not, that I do. 20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me. 21 I find then a law, that, when I would do good, evil is present with me. 22 For I delight in the law of God after the inward man: 23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. 24 O wretched man that I am! who shall deliver me from the body of this death? 25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
So Paul was leading to the conclusion of how he was under the law for which he thanked Jesus Christ for delivering him from the body of death, but he still points out the state of man under the law in verse 25. From which he leads into the 8th chapter about those who do not follow Christ by the religious flesh as one under the law.
Romans 8:1There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. 2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death. 3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: 4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
I can hope in the Lord that He will help you to understand His words for what Paul was conveying about in how he was as Saul, under the law to how he is now, thanks to Jesus Christ.
