no, if the Greek word translated "sin" can be used in the sense which you use it then the greek experts would certainly be aware of that meaning.
Let us look at what you say about those verses;
How can you say that the following verses are referring to the "literal flesh"?
"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" (Ro.7:5).
"But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his" (Ro.8:9).
If Paul is speaking of the "literal flesh" at Romans 8:9 then perhaps you can tell me how it was possible that those to whom his words were addressed were "not in the flesh" or not in a "literal" body?
Paul said "it is sin that dwells in me."
Whether you believe the Word or not is up to you. But sin dwells in believers and must be confessed.
1John 1:9 states that we must confess our sin.
What is sin? Sin has many definitions and takes many forms.
One definition is that it is an attitude of rebellion against God.
That being so, it definitely resides in you. Jesus taught that all sin comes from within, from the heart, and defiles the man. He said: murder, fornication, adultery, thefts, these come from within, from the heart. It was not the things that defiled a man by unwashen hands from without that made a man unclean, but the things that were already within the heart, residing within that made him unclean. Sin resides within.
Jesus taught on the sermon on the mount that it was not the actual act of murder only that was the transgression of the command. But the one that got angry with his brother also committed murder. Why? Because it is conceived in the heart, just like adultery.
He said: "But if a man looks upon a woman and lusts after her, with her already in his heart, he has committed adultery." Sin resides in you. You don't have to physically commit adultery to break the command. You can do it from within. Sin resides within you.
So Paul describes the battle of sin residing in him. He does the things he doesn't want to do, and he doesn't do the things he wants to do. It is sin that dwells in him.
He cries out: "Oh wretched man that I am who shall deliver me from the body of this death."
And then the answer comes:
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. (Romans 7:25)
--The battle is in the mind, from within. Sin is conquered with the mind. "Let this mind be in you which also is in Jesus Christ." Submit your mind to the Lord Jesus Christ. That is the only way to conquer the sin that resides within you. Sin always resides within. Sin is rebellion. It is rebellion against God. It is conceived in the heart. Even our secular courts recognize this when the convict a person for
premeditated murder.
