There's plenty to be gleaned concerning the nature and function of the will, but we can cut to the chase by simply looking at what Paul has to say on the subject in Romans 9.
He begins with this doozy:
"
3For I could wish that myself were accursed from Christ for my brethren, my kinsmen according to the flesh:...etc."
He could will this, but then adds the caveat that it doesn't really matter what he wills because...
"
6Not as though the word of God hath taken none effect."
Ultimately, what matters is what God promises, and one's will cannot usurp the power of God's promise.
"
9For this is the word of promise, "
The gospel writer affirms that it is not we who choose Christ, but Christ who chooses who will follow him. The elect are not the one's doing the electing.
"
11(For the children being not yet born, neither having done any good or evil, that the purpose of God according to ELECTION might stand, not of works, but of him that calleth"
Those works are according to one's own will which Paul has just summarily dismissed as a factor.
Paul then goes on to point out that as unfair as this may seem to those who believe God's justice must include one's freedom to choose, he simply points out that God's justice is a Given.
"
12It was said unto her, The elder shall serve the younger.
13As it is written, Jacob have I loved, but Esau have I hated.
14What shall we say then? Is there unrighteousness with God? God forbid.
15For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion."
Notice who's will is relevant?
"
16So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy."
Notice also that it really doesn't matter if one believes in free will or not because one's free will is not the deciding factor at all. Instead, it is God's mercy which is the deciding factor.
"
18Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth."
The next question Paul poses is one which spotlights the audacity of those who seek only to justify their sin.
"
19Thou wilt say then unto me, Why doth he yet find fault? For who hath resisted his will?"
Even so, once again, Paul cuts through the nonsense, and gets right to the ultimate point which is that God creates for his purposes, not anyone else's. It is idiotic to ask God why he creates someone who is predisposed to sin.
"
20Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus?
21Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour?"
The answer is a resounding "YES". Paul then continues with a hypothetical question which most people are reluctant to consider, especially the prospect that they may be a vessel fitted for destruction. Note that Paul is pointing out that were this the case, it doesn't negate God's righteousness. In fact, it justifies God's righteousness.
"
22What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction:
23And that he might make known the riches of his glory on the vessels of mercy, which he had afore prepared unto glory,
28For he will finish the work, and cut it short in righteousness: because a short work will the Lord make upon the earth."
When humanity chooses to go their own way, we're left with a long drawn out pathetic history spotlighting a testament to human failure.
It doesn't matter what my will is due to the fact that my will is the will of the flesh. I can keep the commandments perfectly, and it only spotlights the glory I have in, with, through, and for my own flesh.
Faith cannot glory in the flesh because the flesh, through many trials and tribulations; can only fail. Paul points to the Old Covenant as a testament to failure.
Again, those who actually hear the gospel message cannot then seek to justify themselves. To try is to fail, but in, with, and through Christ's faith there can only be success.
"
32Wherefore? Because they sought it not by faith, but as it were by the works of the law."
Christ points out that when this process is done in faith, the burden is light and easy. It is all accomplished in, with, through and for Christ. There is no shame in the glorious accomplishments of Christ. Everyone in the bible sees what they believe, and "
whosoever believeth on him shall not be ashamed."
Ultimately, it is "the spirit [who] breathes where HE WILLS. You hear the sound of his voice, but know not where it comes from or where it goes. So it is with everyone who is born of the spirit" John 3:8
The metaphor of birth is apt in that no one wills to be born. Being born is not something a baby does, but something the mother does. Likewise, being begotten is an act of the father, not the son who is begotten. It is according to the will of the father, not the son. Not even Christ's will supersedes that of the father.
Why then would anyone think any different when it comes to their will?
