No problemo.
(Rotherham) Isaiah 64:6 But we have become as one unclean all of us, And, as a garment polluted, were all our righteous doings,--And so we faded like a leaf all of us, And, our iniquity, as a wind, carried us away;
Was Isaiah in the garden to witness firsthand what Adam was like before sinning? NO! Isaiah is a human being used of God to tell God's chosen people of the errors of their ways in an attempt to persuade them to repent of sin.
He is making no statement here about mans abilities, only about his actions. Actions and Abilities are distinctly different aspects.
Abilities denote skill, Actions denote desires!
(Rotherham) Romans 3:10-18 Even as it is written--there is none righteous, not even one,
There is none that discerneth, There is none that seeketh out God:
There is none that discerneth, There is none that seeketh out God:
A sepulchre opened, is their throat, with their tongues, have they used deceit, the poison of asps, is under their lips,
Whose mouth, of cursing and bitterness, is full,
Swift, are their feet to shed blood
Destruction and misery, are in their ways,
And, the way of peace, have they not known:
There is no fear of God before their eyes.
Please note that each phrase here speaks of desire and not ability.
Discerneth is what one does with what one has. That is, one has the ability to discern but does not. You would have us believe that one does not have the ability to discern.
Seeketh: an action that one must have the ability to do, else it is not possible for one to seek out God, but the phrase says, "there is none that seeketh out God" denoting the ability exists but not the desire to do so.
Man has a mouth with which to speak that which is in their heart, but man is using the mouth to speak with deceipt, with cursing and bitterness, therefore it is these things that are in the heart of man. Again, the ability exists, the desire does not!
(Rotherham) Ephesians 2:1 [Unto] you also--being dead by your offences and sins,
Metaphorically and spiritually speaking, man is dead to God because of transgressions of sin. Is man dead? NO! Man lives! But the life is natural physical life without having spiritual life. Does man have the ability to have spiritual life? YES! The same spirit with which man lives the natural life can be reborn into the spiritual life. But man has no ability to cause that rebirth anymore than any man can cause his own natural life. Rebirth (regenation if you desire) comes from divine source outside of man.
(Rotherham) Ephesians 2:5 Although we were dead by our offences, gave us life together with the Christ,--by favour, ye have been saved,--
This is not proof that the ability does not exist? NO! The ability is there or it cannot be redeemed. Redeemed, implies once possessed, then lost, once again gained.
You have failed to prove that man is unable. Let's change the tune to, "Man has the ability, but not the desire because of sin!" That is the reason man is instructed to repent from sinning! So long as man continues to sin, the desire to strive for holiness is stifled.
As you know, I have oft said that man cannot save himself. Man has the ability to have faith. That is demonstrated in whatever state of sin man may be in, for faith is present where knowledge is not. If one has knowledge, for what reason is faith needed. But faith in what? That is where Hearing comes in. Faith in God comes by hearing, the hearing of God's word. Then man having heard God's word can have faith in God, in the same manner (process) that man can have faith in anything. The ability exists in man to have faith. MAN IS ABLE! God made us that way!
Now to overcome man's reluctance!
