CL is right to pin you down on this.
In this reply you are saying that Paul did continue to sin, only it wasn't him but sin that dwelt in him that was doing it.
Did Paul continue in sin because he was not under law but under grace? God forbid.
I'm not saying that Paul did or didn't continue in sin. Or that he continued in sin because he was not under Law.
No, I'm not saying that.
In this thread I'm focusing one a correct exegesis of this particular verse.
We need to make sure we're getting each verse right so that we can have the right idea at the end of it all.
I'm saying that a key point of this passage, the latter half of Romans 7, is to teach that sin resides in the flesh, and that when we are reborn, when we are justified, that we are separated from our flesh, and that though the flesh remain corrupt and enslaved to sin, we are not. In the inner man, by which I think he means the "new creation", we are righteous and enslaved to righteousness.
One of the implications in this understanding is to know that even should we commit sin, which I still do, speaking strictly for me, that the source of this sin is my flesh, and not my new spirit, the child of God, and there is now no condemnation, no guilt or stain.
This is what many people seem to bristle at. This is where the accusations of "license to sin" come in. This when the baby gets thrown out with the bathwater. But we ARE forgiven.
The idea is that once we realize that our sins do not disqualify us from God's help, that in my inner man, I am in communion with God, and with His help, as God works we me, I am obtaining greater control over my flesh. And failure doesn't affect that, God continues His work in me.
Much love!
