1Jo 3:9 No one who is born of God practices sin, because His seed abides in him; and he cannot sin, because he is born of God. (e.g. slave to righteousness)
Paul in Romans 7 continues to fight against the flesh.
Romans 7 has for almost 1700 years (if not longer) been interpreted that Paul was speaking in regards to a non-Christian. "Who will rescue me...? Thanks be to Christ." It was only within the last several hundred years that this has been translated in the cardinal sense of a believer falling away.
But, HD, if the devil, by your theology, is necessarily God's obedient servant doing simply God's will, why would God come to destroy him?
If you have sinned, you have practiced it, have you not? You are putting words into John's writings that are not there. He doens't say "if you sin once, you are ok, only 10 times per month - then you are from the devil".

The chapter uses the first person pronoun "I", indicative of his own personal struggle with sin and the reliance in the end on Jesus Christ to save us from the flesh. According to you, the "non-Christian" won't be making the choice between good and evil, and will always choose the evil, correct? According to Reformed theology, isn't that the anthropology of man? That he can never choose good? There is no such contest within the non-Christian - all are wicked and no one seeks out the Lord? Correct? Now, you are saying something different in that Romans 7 refers only to non-Christians...
