Have you thought through your reasoning? You could say the same about fornication. Is not the command not to fornicate obeyed by ceasing from touching forbidden flesh and keeping down the sinful eye of the flesh? The Sabbath also restricts doing one's own fleshly desires. What you are saying make no sense and sounds like semi-gnosticism.
We have to put to death the [sinful] deeds of the body through the Spirit.
"But I discipline my body and keep it under control, lest after preaching to others I myself should be disqualified." (1 Corinthians 9:27 ESV)
"For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live." (Romans 8:13 ESV)
Abstaining from every sin involves something to do with flesh. Flesh and physical matter are not sinful in and of themselves. The resurrection is a one of literal flesh bodies only they are glorified and immortal.
The Law is spiritual (
Romans 7:14). The Law was given by the Spirit of God:
"And he gave to Moses, when he had finished speaking with him on Mount Sinai, the two tablets of the testimony, tablets of stone,
written with the finger of God." (Exodus 31:18 ESV)
The same Spirit through which Jesus cast out the demons, UNCLEAN spirits:
"But if it is
by the finger of God that I cast out demons, then the kingdom of God has come upon you." (Luke 11:20 ESV)
"But if it is
by the Spirit of God that I cast out demons, then the kingdom of God has come upon you." (Matthew 12:28 ESV)
The Law is of the Spirit, not the flesh. It is a divine Law, not a fleshly Law. And this is why the Spirit leads man to obey it like was quoted already:
Eze 36:26 A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
Eze 36:27 And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.
