No where does it say that man is totaly uterly corrupt.
Corrupt yes but not totaly or he would have no hope of any comprehention of the Spirt at all.
If he was totaly uterly hoplessly corrupt one would get your head kicked in maybe every day or maybe run through with a knife, with not a second thought or care.
He would be just a wild beast, But man is not, it just that he does not know the full truth of right from wrong with regard to Gods ways. as only God is good.
When that dude said to Jesus "good teacher" Jesus seen that this was just a worldly position and that it lacked the Spirit. so he has some good that in he can fathom good to a point but is deluded to fail in understanding as of Jesus true possition.
Our works are just filthy rags because they are not in Christ at all, but only just foolishness, like modern day political correctness is just one of mans gods he made up to feed his ego.
Mans law is just his whims due to his own ego. it lacks the Spirit of God and any salvation in Christ.
Eph 2:1 And you hath he quickened, who were dead in trespasses and sins;
2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
3 Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
4 But God, who is rich in mercy, for his great love wherewith he loved us,
5 Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved
6 And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
7 That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.
If a man is dead how can he do anything to gain access to the Father? The faith that we have to believe is given to us as a gift.
Vs 9 Not of works. You can't do anything to gain access to the Father. You don't even have faith to believe. You and every one who has ever lived or will live have no desire to come to God. The only reason anyone of us have a desire to seek after God is because God gave us that desire.
Not of works, lest any man should boast.
Rom 3:10
As it is written, There is none righteous, no, not one:11 There is none that understandeth, there is none that seeketh after God.
12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
13 Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:
Let me ask you this, what did Christ death on the cross accomplish? Or let me use another way.
"For Whom Did Christ Die?
"The Father imposed his wrath due unto, and the son under went punishment for, either
1. All the sins of all men.
2. All the sins of some men.
3. Some of the sins of all men.
In which case it may be said:
A. That if the last be true, all men have some sins to answer for and so none are saved.
B That if the second be true, then Christ, in their stead suffered for all the sins of all the elect in the whole world, and this is the truth.
C. But if the first be the case, why are not all men free from the punishment due unto their sins?
You answer because of unbelief.
I ask, is this unbelief a sin, or is it not?
If it be, then Christ suffered the punishment due unto it, or he did not.
If he did must that hinder them more than their others sins for which he died?
If he did not, he did not die for all their sins
