You foolish Galatians, who has bewitched you, before whose eyes Jesus Christ was publicly portrayed as crucified? 2 This is the only thing I want to find out from you: did you receive the Spirit by works of [b]the Law, or by hearing [c]with faith? 3 Are you so foolish? Having begun [d]by the Spirit, are you now [e]being perfected by the flesh? 4 Did you [f]suffer so many things in vain—if indeed it was in vain? 5 So then, does He who provides you with the Spirit and works [g]miracles among you, do it by works of [h]the Law, or by hearing [i]with faith?
Would Paul write these words if he actually approved of efforts to follow the Law?
Indeed he would - because Paul knew full well it is still "a sin" - to take God's name in vain -even for Christians.
Rom 7:
7 What shall we say then? Is the Law sin? Far from it! On the contrary, I would not have come to know sin except through the Law; for I would not have known about coveting if the Law had not said, “You shall not covet.” ...12 So then, the Law is holy, and the commandment is holy and righteous and good.
13 Therefore did that which is good become a cause of death for me? Far from it! Rather it was sin, in order that it might be shown to be sin by bringing about my death through that which is good, so that through the commandment sin would become utterly sinful.
14 For we know that the Law is spiritual, but I am fleshly, sold into bondage to sin. ...16 However, if I do the very thing I do not want to do, I agree with the Law, that the Law is good. 17 But now, no longer am I the one doing it, but sin that dwells in me. 18 For I know that good does not dwell in me, that is, in my flesh; for the willing is present in me, but the doing of the good is not. 19 For the good that I want, I do not do, but I practice the very evil that I do not want. 20 But if I do the very thing I do not want, I am no longer the one doing it, but sin that dwells in me.
21 I find then the principle that evil is present in me, the one who wants to do good. 22 For I joyfully agree with the law of God in the inner person,
Paul says that a lost person does not submit to the Law of God - neither indeed CAN they.
Rom 8
5 For those who are in accord with the flesh set their minds on the things of the flesh, but those who are in accord with the Spirit, the things of the Spirit. 6 For the mind set on the flesh is death, but the mind set on the Spirit is life and peace, 7 because the mind set on the flesh is hostile toward God; for it does not subject itself to the law of God, for it is not even able to do so, 8 and those who are in the flesh cannot please God.
9 However, you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you.
