I disagree. Paul states in Romans 7:25 that he serves the law of God with his mind. It's not possible for a person to be serving the law of God with his mind if he is doing any of the acts Paul listed in Galatians 5:19-21. He meant his flesh serves the law of sin by dying, not that he still struggled with sin. The things he did that he didn't want to do (Ro 7:20) are unintentional acts like touching unclean things and animals, and also bodily functions like nocturnal emissions. Wilful sin is doing what you want to do, not doing what you don't want to do.
Rom 7:21 I find then a law, that, when I would do good, evil is present with me.
Rom 7:22 For I delight in the law of God after the inward man:
Not the state of an unsaved person, but of a saved person struggling with his flesh, until delivered from its power.
