Unbelieving sinners have no free will pertaining to sin and God: they will sin by nature and cannot possibly serve and please God.
Only believers of Jesus born again of God have the seed of God in them to have free will on earth to choose to serve sin or God.
To say we have no such free will, while the seed of God remains in us, is to say God has no power nor free will against sin to give us.
Those who call upon a 'grace' without free will to sin or not to sin, are calling upon a lie to save them, not from sin, but from judgement of God against all sin.
It is a strong delusion that practicing sinners against God, who claim to believe Jesus, are calling upon to save them, while yet willingly in their sins. They excuse their sins and repent not, because they frustrate the grace of God to be free of sin's nature, and reject the power of God to do what no unbeliever can do: to yield ourselves to sin and serve sin, or to yield ourselves to righteousness and serve God.
Unlike the devils that believe there is one God and quake and tremble at His judgment, they have made themselves by vain imagination free of the judgment of God, while living like devils that have no choice but to sin.
Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead.
Only them that are alive from the dead have power to yield themselves to God. Them that have no so power, are not alive from the dead. And them that are alive from the dead, that claim there is no such power and willfully refuse it by grace, are fallen from grace of God, while believing in their own grace of sin.
The salvation by grace of God is to be delivered from the bondage of sin, so that we may now have freedom and liberty in Christ to choose to sin or not.
Unbelievers born of the flesh and not of the Spirit have no such liberty nor freedom of will to choose one or the other:
Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.
Such Scripture only speaks to them that believe Jesus, not to them that believe not, especially not to those that choose to believe a lie and be damned: that the grace of unconditional salvation gives no freedom of will to choose service to sin unto death or service to God unto righteousness and eternal life.
All such liars against Scripture are far worse off than the uncircumscribed of the world, even as their willingly sinful state is far worse than the ignorant unbelievers of the world who know not God, and have no choice but to sin. (Matthew 12:45) (2 Peter 2:20)
They were clean escaped from the bondage of sin, being made free from sin by grace of God and cleansed of all sin with power of God to and yield by choice not to sin, only to then believe a lie that allows them to return to sin willfully, and so make themselves twofold more children of hell than before.
Before Christ they were servants to sin without choice, as were we all, but now, unlike all, they are servants to sin with choice, claiming no choice at all:
But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!
Grace that is blind to sin and gives no power nor freedom to choose to sin or not, is not grace of God, but peace with the devil and covenant with hell:
Because ye have said, We have made a covenant with death, and with hell are we at agreement; when the overflowing scourge shall pass through, it shall not come unto us: for we have made lies our refuge, and under falsehood have we hid ourselves. (Isaiah 28)
Which is why blind grace lovers, that are lovers of their own grace and pleasures more than are lovers of God (2 Tim 3), hate the law of God lovers, because they that abide lawful by grace of God condemn their unrighteous grace:
For this is the message that ye heard from the beginning, that we should love one another. Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous. Marvel not, my brethren, if the world hate you.
Blind grace lovers do not love them that love the law of God, and so call them grace-haters.
Which is true: I do hate blind grace, and by grace of God, I will not receive it to my own destruction.
Willfully blind grace lovers cannot love the law of Christ, and will not be subject to it, because they choose the carnal mind that is at enmity with God and reject any law of Christ that comes with His grace to do it.
For not the hearers of the law are just before God, but the doers of the law shall be justified...But be ye doers of the word, and not hearers only, deceiving your own selves.
The law of Christ and His Word are the same, and them that claim salvation without His law, are them that are hearing the word of another gospel, that is cursed: the gospel of a blind grace without power of will to choose to sin or not to sin.
Blind grace like blind justice is foolishly judges with an appearance of righteousness, that is not righteousness of God at all, nor His faith, nor His grace, nor His judgment against all sin.
