So there IS a particular theological implication in that you think its ONLY by the power of the Spirit can one be changed, as if people are robots who can't possibly fix themselves without this Deterministic factor. Do you have scripture to support this view?
You'll find ample scripture to support that, but you will find no scripture to support the idea that it's ever possible for any man to clean up their own act and be declared righteous on their own.
 
Matthew 5
You therefore must be perfect, as your heavenly Father is perfect.
Romans 3:
10 As it is written:
"There is no one righteous, not even one;
Matthew 19
25 When the disciples heard this, they were greatly astonished, saying, "Who then can be saved?" 26 But Jesus looked at them and said,
"With man this is impossible, but with God all things are possible."
Romans 3
20
Therefore no one will be declared righteous in God’s sight by the works of the law; rather, through the law we become conscious of our sin.
Romans 5
20 The law was brought in so that the trespass might increase. But where sin increased, grace increased all the more,
Hebrews 7
19
(for the law made nothing perfect); but on the other hand, a better hope is introduced, through which we draw near to God.
Hebrews 10
For since the law has but a shadow of the good things to come instead of the true form of these realities, it can never, by the same sacrifices that are continually offered every year, make perfect those who draw near.
 
John 3
Jesus answered him, "Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God." 4 Nicodemus said to him, "How can a man be born when he is old? Can he enter a second time into his mother's womb and be born?" 5 Jesus answered, "Truly, truly,
I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. 6 That which is born of the flesh is flesh, and
that which is born of the Spirit is spirit. 7 Do not marvel that I said to you, ‘You must be born again.’ 8 The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit."
 
Ezekiel 37
3 And he said to me, "Son of man, can these bones live?" And I answered, "O Lord God, you know." 4 Then he said to me, "Prophesy over these bones, and say to them, O dry bones, hear the word of the Lord. 5 Thus says the Lord God to these bones:
Behold, I will cause breath to enter you, and you shall live. 6 And I will lay sinews upon you, and will cause flesh to come upon you, and cover you with skin,
and put breath in you, and you shall live, and you shall know that I am the Lord."
Genesis 2:7
7 then the Lord God formed the man of dust from the ground
and breathed into his nostrils the breath of life, and the man became a living creature.
 
Romans 8
3
For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh, 4 in order that the righteous requirement of the law might be fulfilled in us,
who walk not according to the flesh but according to the Spirit. 5 For those who live according to the flesh set their minds on the things of the flesh,
but those who live according to the Spirit set their minds on the things of the Spirit. 6 For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace. 7 For the mind that is set on the flesh is hostile to God, for it does not submit to God's law; indeed, it cannot. 8 Those who are in the flesh cannot please God.
9
You, however, are not in the flesh but in the Spirit, if in fact the Spirit of God dwells in you. Anyone who does not have the Spirit of Christ does not belong to him. 10 But if Christ is in you, although the body is dead because of sin, the Spirit is life because of righteousness. 11
If the Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you.

Likewise the Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words. 27 And he who searches hearts knows what is the mind of the Spirit, because the Spirit intercedes for the saints according to the will of God. 28 And we know that for those who love God all things work together for good, for those who are called according to his purpose. 29 For those whom he foreknew he also predestined to be
conformed to the image of his Son, in order that he might be the firstborn among many brothers. 30 And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified.
 
2 corinthians 3
17 Now
the Lord is the Spirit, and
where the Spirit of the Lord is, there is freedom. 18 And we all, with unveiled face,
beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For
this comes from the Lord who is the Spirit.
 
Philipians 1
6 And I am sure of this, that
he who began a good work in you will bring it to completion at the day of Jesus Christ.
 
Galatians 2
20 I have been crucified with Christ. It is no longer I who live, but Christ who lives in me.
Galatians 5
5
For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery.
2 Look: I, Paul, say to you that if you accept circumcision, Christ will be of no advantage to you. 3 I testify again to every man who accepts circumcision that he is obligated to keep the whole law. 4 You are severed from Christ, you who would be justified by the law; you have fallen away from grace. 5
For through the Spirit, by faith, we ourselves eagerly wait for the hope of righteousness. 6
For in Christ Jesus neither circumcision nor uncircumcision counts for anything, but only faith working through love.
...
16 But I say,
walk by the Spirit, and you will not gratify the desires of the flesh. 17 For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh, for these are opposed to each other, to keep you from doing the things you want to do. 18
But if you are led by the Spirit, you are not under the law. 19 Now the works of the flesh are evident: sexual immorality, impurity, sensuality, 20 idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, 21 envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God. 22
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control; against such things there is no law. 24 And those who belong to Christ Jesus have crucified the flesh with its passions and desires.
25
If we live by the Spirit, let us also keep in step with the Spirit.
 
Ephesians 4
17 Now this I say and testify in the Lord, that you must no longer walk as the Gentiles do, in the futility of their minds. 18 They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them, due to their hardness of heart. 19 They have become callous and have given themselves up to sensuality, greedy to practice every kind of impurity. 20 But that is not the way you learned Christ!— 21 assuming that you have heard about him and were taught in him, as the truth is in Jesus, 22 to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, 23 and to
be renewed in the spirit of your minds, 24 and to put on the new self, created after the likeness of God in true righteousness and holiness.
Romans 12
2 Do not be conformed to this world, but
be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
 
To sum it all up:
Supernatural intervention via the Holy Spirit is required to remove the damage and influences that keep us walking in opposition to God.
