Pay attention, Van. If you can't grasp the free will in these verses and how the Holy Spirit works to enlighten man of the Gospel, then I'll be happy to explain it in detail from these verse.
Rom. 10:14-17
"How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!
But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?
So then faith cometh by hearing, and hearing by the word of God."
Let me add this, this is how the Holy Spirit uses the Word of God to penetrate the cold hard heart of depraved man.
Heb. 4:12
"For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart."
Christ told us He would send the Holy Spirit (the Comforter) to convict of sin, of righteousness, and of judgement.
This is how the Holy Spirit does it when you and I present the Gospel.
