Bob, Mary, Joe, Roy, Jill, Harry, Ralph, Rudolph, Gary, Marlene, Justine, et al, do not have free will. Our wills are never free. Our will is bound to our nature. When lost, our will was enslaved to sin and Satan, seeing we were dead in sin. It takes God to change our nature, and by changing our nature, our will is changed as well.
”No one can serve two masters; for either he will hate the one and love the other, or he will be devoted to one and despise the other. You cannot serve God and wealth.”[Matthew 6:24] Man is either a slave to Satan or a slave to God.
What then? Shall we sin because we are not under law but under grace? May it never be! Do you not know that when you present yourselves to someone as slaves for obedience, you are slaves of the one whom you obey, either of sin resulting in death, or of obedience resulting in righteousness? But thanks be to God that though you were slaves of sin, you became obedient from the heart to that form of teaching to which you were committed, and having been freed from sin, you became slaves of righteousness. I am speaking in human terms because of the weakness of your flesh. For just as you presented your members as slaves to impurity and to lawlessness, resulting in further lawlessness, so now present your members as slaves to righteousness, resulting in sanctification. For when you were slaves of sin, you were free in regard to righteousness. Therefore what benefit were you then deriving from the things of which you are now ashamed? For the outcome of those things is death. But now having been freed from sin and enslaved to God, you derive your benefit, resulting in sanctification, and the outcome, eternal life. For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.[Romans 6:15-23]
No one is free in regards to their will. It says that when we were slaves of sin, we were free in regards to righteousness. What Paul meant was we were not righteous when we were slaves to sin. But no one has a free will. There is always something driving us to choose that which we choose.
