Romans chapter seven shows FLESH SERVING YOU and in Romans 7:12 KJV God's Law is introduced and you recognizing them (The Commandments) allows flesh to serve you by playing its role:
Wherefore the law is holy, and the commandment holy, and just, and good.
God's commandments, given to Moses, are spiritual and purposeful and Romans 7:14 KJV show you being carnal. The reason God made you carnal is that placing you the flesh is how He choose to expose you to sin:
For we know that the law is spiritual: but I am carnal, sold under sin.
The law is spiritual because it is your spirit (mind) that recognizes sin, enabling you to deal with it.
Sold under sin represents the fact that everybody's flesh body exposes them to sin and Romans 7:15 KJV shows this creating a dilemma for Paul, you, and me:
For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
Doing what you hate is sin, something you and Paul share one and alike and just like Paul, you may recall sin you have committed that you have asked others not to commit.
Romans 7:16 KJV shows recognizing sin to be just as important as consenting to God's Law is necessary and good.
If then I do that which I would not, I consent unto the law that it is good.
God's Commandments are as important as they are good for a reason; they allow you to recognize the sin that Romans 7:17 KJV shows dwelling in you:
Now then it is no more I that do it, but sin that dwelleth in me.
Does blaming the sin that you commonly repeat on the sin itself remind you of the old saying, "The Devil made me do it? The Devil is sin and he continually attacks you through your flesh; that same old sin seems to keep repeating.
Romans 7:18 KJV shows Satan is with you for the duration; as long as you are in the flesh Satan's access remains because your fleshly will to sin remains:
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.
Finding good to do is a bit more difficult than accepting the sin that Satan is offering and when you follow Paul in Romans 7:19 KJV you see it the same for him:
For the good that I would I do not: but the evil which I would not, that I do.
Paul sins and yours take place for the same reason;
