As long as our flesh lives we serve the law of sin and death. Once we put the flesh to death with Christ, we are no longer compelled to live after the flesh but the Spirit. However, people can choose to live after the flesh, but that proves who their father really is. The laws of God always will exist, if we live by the flesh we will continue to offend God and His holy laws and the end result will not be good. There is no law against the Spirit of God and the things it causes us to do.
Galatians 5
6 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
18 But if ye be led of the Spirit, ye are not under the law.
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.
22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
23 Meekness, temperance: against such there is no law.
24 And they that are Christ's have crucified the flesh with the affections and lusts.
