Bob, my wife just pointed out, after reading to her our exchanges, that you seem to want to have control over God's word. God's word says that we're sinners and require His grace to obey. In this we follow God despite our flawed obedience. God only wants us to abide in Christ, even if we can't do it perfectly.
You don't seem to accept that formula. For you, any disobedience is a choice to disobey God, and not so much something innately affecting our ability to obey. Your assumption seems to be that we don't have to sin?
In reality, Sin is a part of our nature, and not our willful obedience, as such. It is an imperative, that we rely upon God's virtue even as our nature tends to resist God's word. That is how God's word expresses it, and to deny that it to wrest control away from God and His word, putting control exclusively in our own hands, where our disobedience will become even more manifest.
To deny our need for Grace is itself a form of sin, because it assumes we have control where it has been taken away from us since the Fall of Man. God has indeed reduced us in weakness to the need for God's Grace. But this Grace does enable us to obey, even in our weak, sinful flesh.
