How one comes to belief is stated in:
Faith is a gift (Php 1:29).
Php 1:29 For unto you it is given in the behalf of Christ, not only to believe on him, but also to suffer for his sake;
I cannot deny that the Spirit works on the children of wrath so they can (Does not God desire ALL to come to a faith which saves):
Joh 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:
Faith is by grace (Ac 18:27).
Act 18:27 And when he was disposed to pass into Achaia, the brethren wrote, exhorting the disciples to receive him: who, when he was come, helped them much which had believed through grace:
And by the gracious act of God, salvation is through faith and no longer through the Law.
Rom 11:6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.
And how does one believe through grace:
Joh 6:28 Then said they unto him, What shall we do, that we might work the works of God?
Joh 6:29 Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
One must have the Spirit of God to receive the things that come from the Spirit of God; e.g., faith (1Co 2:14).
And how do we receive the Spirit of God:
Gal 3:2 This only would I learn of you, Received ye the Spirit by the works of the law, or by the hearing of faith?
How does one hear the faith:
Act 15:7 And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe.
Act 15:8 And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us;
Rom 10:13 For whosoever shall call upon the name of the Lord shall be saved.
Rom 10:14 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?
Rom 10:15 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!
Only the children of God can hear (Jn 8:43-44, 47).
Joh 8:43 Why do ye not understand my speech? even because ye cannot hear my word.
Joh 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
Joh 8:47 He that is of God heareth God's words: ye therefore hear them not, because ye are not of God.
Is it not true that the children of the flesh mentioned in 1 Corinthians 2 is also mentioned here and would seem they have chosen the flesh over the spirit:
Rom 9:8 That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.
