Below are just a few verses which clearly teach that there are divine constraints upon mankind's "will":
Mat 4:4 But he answered and said, it is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.
John 1:12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: 13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
Prov 16:1 The preparations of the heart in man, and the answer of the tongue, is from the LORD.
Prov 20:24 Man's goings are of the LORD; how can a man then understand his own way?
Isa 26:12 O Jehovah, thou appointest peace to us, for, all our works also thou hast wrought for us.
Jer 10:23 I know, Jehovah, that the way of man is not his own; it is not in a man that walketh to direct his steps.
Deut 29:4 Yet the LORD hath not given you a heart to perceive, and eyes to see, and ears to hear, unto this day.
Isa 44:18 They have not known nor understood: for he hath shut their eyes, that they cannot see; and their hearts, that they cannot understand.
Isa 64:8 But now, O LORD, thou art our father; we are the clay, and thou our potter; and we all are the work of thy hand.
Prov 21:1 The king's heart is in the hand of the LORD, as the rivers of water: he turneth it whithersoever he will.
In this age, God's Word teaches that only those people who are blessed from the foundation of the world will be saved:
Eph 1:11 In whom also we have obtained an inheritance, being predestinated according to the purpose of him who worketh all things after the counsel of his own will:
2Tim 1:9 who did save us, and did call with a holy calling, not according to our works, but according to His own purpose and grace, that was given to us in Christ Jesus, before the times of the ages…
Rom 8:30 Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.
Rom 9:11 (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;)
Paul was even asked about why God still finds fault with mankind given the truth that God's "will" rules over our "will":
Rom 9:15 For 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. 16 So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy. 17 For the scripture saith unto Pharaoh, even for this same purpose have I raised thee up, that I might shew my power in thee, and that my name might be declared throughout all the earth. 18 Therefore, hath he mercy on whom he will have mercy, and whom he will he hardeneth. 19 Thou wilt say then unto me, why doth he yet find fault? For who hath resisted his will?
How can you read these scriptures which I have posted above and come away with the conclusion that mankind has a free will to determine their own destiny?
