There are other verses (see the Video in the first post) that indicate that "acts of the flesh" is actually trying to follow the law. Let's face it: decent people all try to do the right thing, but we do it by our own strength - we follow our flesh (eg. the Buddhists). Sowing to the Spirit is forgoing the flesh (depending on works) and having faith in His grace. If we interpret "sowing in the flesh" and "acts of the flesh" as trying to follow the law, then suddenly Gal 6:8 has a whole new meaning.
It is true that the works of the flesh is in reference to the Law in Galatians 6:8. But it is in reference to the Old Law. Specifically circumcision in this particular instance.
"For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh." (Galatians 6:13).
It is sin to try and go back to the Old Law of circumcision. For if we seek to be circumcised, Christ will profit us nothing (Galatians 5:2).
But works of the flesh is also in reference to serious sins in general, too. How so? Skip back a chapter and it says this,
19 "Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God." (Galatians 5:19-21).
They which do such things shall not inherit the Kingdom of God. So yes. Christians are under some kind of laws. For we cannot go around murdering, getting drunk, sleeping around, and or indulging in witchcraft without the consequence of not inheriting the kingdom of God (if we do not repent of such sins).
