All of the the wrong views about Romans 7 being written about a believer, are INVALID because the subject person has not died to the law, but is very much alive to it. One cannot have the Spirit if they are alive to law, they must first die to law. The Spirit can only inhabit a dead to the law person, it is only the Spirit that makes a Christian a Christian, one who is dead to the law, that makes one alive to God.
Since the person in Romans 7 is very obviously still alive to the law (otherwise they would not still be talking about it) then neither are they Christian, nor do they possess the Spirit. They are still dead under the law, in the law. Christians are those not under law, not in the flesh at all. Only law makes flesh alive to sin, the Spirit makes the spirit alive and puts natural flesh to death.
“Those who are His have crucified the flesh with its passions and desires”. “One died for all, therefore all died”.
[Romans 4:15 “…for the law brings about wrath, but where there is no law, neither is there violation”.][A legalist cannot inherit the Spirit of Christ][but only the legalistic mind can interpret this because it is aimed at legalists][And this may be why some godly people get it wrong]
