Until one is regenerated and given a new nature, they are locked in unbelief Rom 11:32
32 For God hath concluded them all in unbelief, that he might have mercy upon all.
Mercy here gives faith to believe Vs 30
30 For as ye in times past have not believed God, yet have now obtained mercy through their unbelief:
This also proves by nature we dont have freewill to believe, being confined to unbelief
In context this is a reference to the Jews
Romans 11:26–32 (KJV 1900) — 26 And so all
Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: 27 For this is my covenant unto them, when I shall take away their sins. 28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers’ sakes. 29 For the gifts and calling of God are without repentance. 30
For as ye in times past have not believed God, yet have now obtained mercy through their unbelief: 31 Even so have these also now not believed, that through your mercy they also may obtain mercy. 32 For God hath concluded
them all in unbelief, that he might have mercy upon all.
And nothing is stated about being given faith to believe.
Because the Jews were not believing the disciples were sent to the Gentiles
Acts 13:46–47 (LEB) — 46 Both Paul and Barnabas spoke boldly and said, “It was necessary that the word of God be spoken first to you, since you reject it and do not consider yourselves worthy of eternal life! Behold, we are turning to the Gentiles! 47 For so the Lord has commanded us: ‘I have appointed you to be a light for the Gentiles, that you would bring salvation to the end of the earth.’
Romans 11:11–13 (LEB) — 11 I say then, they did not stumble so that they fell, did they? May it never be! But by their trespass, salvation has come to the Gentiles, in order to provoke them to jealousy. 12 And if their trespass means riches for the world and their loss means riches for the Gentiles, how much more will their fullness mean? 13 Now I am speaking to you Gentiles. Therefore, inasmuch as I am apostle to the Gentiles, I promote my ministry,
Acts 28:25–28 (LEB) — 25 So being in disagreement with one another, they began to leave after Paul made one statement: “The Holy Spirit spoke rightly through the prophet Isaiah to your fathers, 26 saying, ‘Go to this people and say, “You will keep on hearing and will never understand, and you will keep on seeing and will never perceive. 27 For the heart of this people has become dull, and with their ears they hear with difficulty, and they have shut their eyes, lest they see with their eyes, and hear with their ears, and understand with their heart, and turn, and I would heal them.” ’ 28 Therefore let it be known to you that this salvation of God has been sent to the Gentiles. They also will listen!”
