Uh, man is not wounded. He is DEAD. Demised. An ex-parrot. The Holy Spirit is the only one who can make him ALIVE (Quicken) to Christ to where he will choose Christ.
Genesis 6:5 And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
Genesis 8:21 And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man's sake; for the imagination of man's heart is evil from his youth; neither will I again smite any more every thing living, as I have done.
Job 15:14-16 What is man, that he should be clean? and he which is born of a woman, that he should be righteous? Behold, he putteth no trust in his saints; yea, the heavens are not clean in his sight. How much more abominable and filthy is man, which drinketh iniquity like water?
Psalms 51:5 Behold, I was shapen in iniquity, and in sin did my mother conceive me.
John 6:65 And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.
You may believe what you will, but the mainstream Protestant interpretation (I realize I am generalizing - not all Protestants hold to your idea of the totally corrupt man) is incorrect on Romans 3. One doesn't need to be a Catholic to figure that out. I have already detailed my area of disagreement.
As to man requiring the Holy Spirit, I do not believe I said man could EVER save Himself. There is no need for the false dichotomy - in other words, God saves man, but that does not exclude man. One does not have to be dead to require God's salvation.
There is no point in posting Scriptures on this issue - because there are dozens and dozens of them that tell of men being righteous (as a result of God, of course). I will take your word that you claim to be familiar with Scriptures and can find these yourself.
Merry Christmas
