Even James said anything apapret from faith is sin! So even mans "good deeds" are poisoned by his sin nature.
Paukl went on in Corinthians to say the natural man (unsaved) does not even perceive the things of God for they are foolish to HIm. I am not one who easily redefines passages of Scripture. Even if they do paint a bleak picture of man apart from Jesus. If god wanted to say autonomous man ( which I assume you mean simply somebody who just wants to do their own thing as in very selfish) He would have said so. God is far more adept at grammart tthan we are.
Well yes, I wouldn't want you to accept my word for anything. By all means, determine what the Scriptures are saying, and please note if what I say is in the same spirit and intent as that which the Scriptures say! I'm not interested in saying anything else!
But the Scriptures tell stories, and do not always provide a systematic theology. In ancient times all we get are stories and outlines of God's overall intentions with respect to human history. It is for us to look back and figure out how what happened in ancient times relates to what we have today. Today we do have a systematic theology, and that's what God used Paul for.
And so, I'm interested in explaining what Paul is saying, because indeed even Peter explained that Paul is difficult to grasp at times. When Paul uses the word "flesh," he obviously is not referring to our "carcass." ;) So we have to decipher what he means by the choice of that word.
My thought is that it goes back to Eden where Man chose against God's word and against his own created nature to obey his own carnal interests, ie the things he saw and wanted. So for me, the "flesh" does refer to "autonomous man," ie Man doing his own thing, with no regard for God's guidance and virtue.
Since acting apart from the will of God causes us to lose virtue, yes, doing supposedly "good works" is poisoned by our own self-interest. God may use it for good for others, but it is not, in and of itself, "good."
This is very different from Man actually doing good. People who are generally "autonomous," living apart from the will of God, sometimes genuinely choose to do good. They cooperate with God's will and word. Therefore, true virtue is in it. Consider that Jesus "loved" the Rich Young Ruler...
Mark 10.17 As Jesus started on his way, a man ran up to him and fell on his knees before him. “Good teacher,” he asked, “what must I do to inherit eternal life?”
18 “Why do you call me good?” Jesus answered. “No one is good—except God alone. 19 You know the commandments: ‘You shall not murder, you shall not commit adultery, you shall not steal, you shall not give false testimony, you shall not defraud, honor your father and mother.’”
20 “Teacher,” he declared, “all these I have kept since I was a boy.”
21 Jesus looked at him and loved him.
But this good, being authentic good, cannot achieve eternal life. Goodness alone does not achieve eternal life. Eternal Life comes from embracing all of God, His entire will, rejecting all evil. We submit ourselves and our will to the word of God. Even though we be imperfect, we cast ourselves on God for His help in living a life of dependence upon Him.
So I'm arguing 2 things here. 1) Man may do an artifical "good," by doing what he thinks is good, but is actually self-interest. And 2) Man may do authentic good, without achieving eternal life in doing so.
Man achieves Salvation when he commits his entire life and will to the Lord. In this way he achieves cleansing from sin, by depending on nothing he does in and of himself. He recognizes, rightly, that all true good comes from God, and that to be saved we must commit entirely to Him as the good, rejecting all evil as autonomous living.
