Hey james..send me a message with what you are saying ..I find it hard to piece things together from different posts..it's me..not you. I'd rather to sit down and read in one place what the thoughts are so that I can get a clearer understanding of what is being said...it is definitely a complex subject...lol
It is simple. You have just admitted the flesh/sin reigned in Paul in rom7:14-25. So in those verses we agree sin was Paul's master.
According to rom 6:14, sin will not be the Christians master for they are not under law but under grace. Therefore in ch 7:14-25 Paul must have been speaking of when he was under the law.
The reason I emphasised he sinned in his old(Adamic) nature, is because of a couple of posts hrftd wrote earlier.
