"Free" Will?

This was posted on Monergism.com. I added some relevant content:

We are dependent on God, not only for redemption itself but for our faith in the Redeemer; not only for the gift of His Son but for the Holy Ghost for our conversion."
- Jonathan Edwards in a public lecture in Boston July 8, 1731

Can a person come to faith in Jesus Christ apart from the Holy Spirit? Let us see what the Scripture says:

~1 Cor 12:3 “Therefore I make known to you that no one speaking by the Spirit of God calls Jesus accursed, and no one can say that Jesus is Lord except by the Holy Spirit"

~John 6:63 "It is the Spirit who gives life; the flesh profits nothing. The words that I speak to you are spirit, and they are life”

~1 Thess 1:4, 5 “knowing, beloved brethren, your election by God. For our gospel did not come to you in word only, but also in power, and in the Holy Spirit and in much assurance, as you know what kind of men we were among you for your sake"

If you answer in the negative (with Scripture), then you affirm that if (natural) man is left to himself he has no free will. If the will were naturally free then there would be no need for grace or the Holy Spirit whatsoever... we could simply exert our natural will to obey all of God's commands, including the command to come to Christ. But in the New Testament Jesus defines freedom as freedom FROM slavery to sin, something, the Scripture declares, only the Son can grant us. 

~John 8:34-47 “Jesus answered them, “ Most assuredly, I say to you, whoever commits sin is a slave of sin. And a slave does not abide in the house forever, but a son abides forever. Therefore if the Son makes you free, you shall be free indeed. I know that you are Abraham's descendants, but you seek to kill Me, because My word has no place in you. I speak what I have seen with My Father, and you do what you have seen with your father.” They answered and said to Him, “Abraham is our father.” Jesus said to them, “ If you were Abraham's children, you would do the works of Abraham. But now you seek to kill Me, a Man who has told you the truth which I heard from God. Abraham did not do this. You do the deeds of your father.” Then they said to Him, “We were not born of fornication; we have one Father—God.” Jesus said to them, “ If God were your Father, you would love Me, for I proceeded forth and came from God; nor have I come of Myself, but He sent Me. Why do you not understand My speech? Because you are not able to listen to My word. You are of your father the devil, and the desires of your father you want to do. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it. But because I tell the truth, you do not believe Me. Which of you convicts Me of sin? And if I tell the truth, why do you not believe Me? He who is of God hears God's words; therefore you do not hear, because you are not of God.” 

~John 6:65 And He said, “Therefore I have said to you that no one can come to Me unless it has been granted to him by My Father.” 

~Rom 6:7 “For he who has died has been freed from sin"

~Rom 6:17-18 “But God be thanked that though you were slaves of sin, yet you obeyed from the heart that form of doctrine to which you were delivered. And having been set free from sin, you became slaves of righteousness"

So any time we acknowledge the need for grace, we are acknowledging (along with the Scriptures) man's bondage to sin and his moral inability in both his affections and his will to come to Christ.
