Hearing in Rom 10:17 is not regeneration.
akoé - hearing, faculty of hearing, ear; report, rumor.
We can see how it is commonly used in other scriptures:
Mk 7:35: "At this, the man’s ears were opened, his tongue was loosened and he began to speak plainly." (Jesus healing a deaf man)
Matt 4:23-24: "Jesus went throughout Galilee, teaching in their synagogues, proclaiming the good news of the kingdom, and healing every disease and sickness among the people.
News about him spread all over Syria, and people brought to him all who were ill with various diseases, those suffering severe pain, the demon-possessed, those having seizures, and the paralyzed; and he healed them."
Gal 3:2 "I would like to learn just one thing from you: Did you receive the Spirit by the works of the law,
or by believing what you heard?" (Note that they had to believe what they heard to receive the Spirit - not vice versa)
II Thess 2:13: "And we also thank God continually because, when you received the word of God,
which you heard from us,
you accepted it not as a human word, but as it actually is, the word of God, which is indeed at work in you who believe. "
This shows how 'faith comes by hearing' - not by a regenerated heart that allows faith, but by the acceptance of the listener that the good news is not of human origin, but the word of God.
The word 'accept' here is "
paralambánō (from
3844 /pará, "from close-alongside" and
2983 /lambánō, "
aggressively take") –
to take (receive) by showing strong personal initiative."
Strong's Greek: 3880. παραλαμβάνω (paralambanó) -- to receive from
Heb 5:11 "About this we have much to say, and it is hard to explain, since you have become dull of hearing." (Not 'dull of regeneration' - which would make little sense even as an idiom for not trying to understand. These people he is talking to are already believers as well, but ones who are stagnating in their growth rather than growing to maturity.)
Matt 24:6: "And
you will hear of wars and rumors of wars. See that you are not alarmed, for this must take place, but the end is not yet."
Etc. Nothing in the concept of 'hearing' equates it to spiritual regeneration.
"But what does it say? "THE WORD IS NEAR YOU, IN YOUR MOUTH AND IN YOUR HEART "-- that is, the word of faith which we are preaching, that if you confess with your mouth, “Jesus is Lord,” and believe in your heart that God raised Him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved.…" Rom 10:8-10
Paul doesn't say, "The word is only near some hearts, because they receive a new heart so they can believe, but for others the word is far off, so they can't believe."
It is actually a reference back to Dueteronomy 30:11-14
Now what I am commanding you today is not too difficult for you or beyond your reach. It is not up in heaven, so that you have to ask, “Who will ascend into heaven to get it and proclaim it to us so we may obey it?” Nor is it beyond the sea, so that you have to ask, “Who will cross the sea to get it and proclaim it to us so we may obey it?”
No, the word is very near you; it is in your mouth and in your heart so you may obey it."
Man can never use the excuse of "it was impossible for me" to say why he declined to believe, as it is possible for everyone to believe the gospel when they hear it!
We also see Paul speaking of the persuasive power of the gospel (not a new heart preceding faith) in I Cor 2:4-5:
"My message and my preaching were not with wise and persuasive words, but with a demonstration of the Spirit’s power, so that your faith might not rest on human wisdom, but on God’s power."
Regeneration isn't a common term in scripture, but it has one passage that details it: Tit 3:5-7
"...he saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal/regeneration by the Holy Spirit, whom he poured out on us generously through Jesus Christ our Savior, so that, having been justified by his grace, we might become heirs having the hope of eternal life."
The renewal by the Spirit is tied in with the 'washing of rebirth,' the pouring out of the spirit, and justification by grace.
Justification comes by faith, not before faith (Rom 4:2-10, Rom 4:23-24, Gal 2:16, Acts 13:39, etc.)
The washing of rebirth is baptism (I Pet 3:21, I Tim 1:5, ph 4:4-6, II Cor 5:14-17, Col 2:11-13, etc.)
Note that faith precedes rising to a new life in the power of God (Col 2:11-13)
The pouring out of the Spirit also follows faith and does not precede it: (Gal 3:2, Acts 10:45, Rom 5:1-11, etc.)
Now, I am assuming that two passages your comment obliquely adresses are Ezek 36:22-36 and I Cor 2:6-16.
The first is a prophecy regarding Israel, both God's punishment on them and a promise to one day bring them back to their nation, which has yet to be completely fulfilled.
"‘...For I will take you out of the nations; I will gather you from all the countries and bring you back into your own land. I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your impurities and from all your idols. I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh. And I will put my Spirit in you and move you to follow my decrees and be careful to keep my laws. Then you will live in the land I gave your ancestors; you will be my people, and I will be your God...." Ezek 36:24-28
Nothing in that prophecy mandates that anyone receive a new heart before they can respond to the gospel in faith. The passage certainly contains many allusions to baptism, receiving the Spirit, and walking by the Spirit - giving hope that one day Israel will turn to faith in Christ.
The other passage, I Cor 2:6-16, is about "
a message of wisdom among the mature," - not among unbelievers. It speaks of how believers have the mind of Christ and the Spirit so they may understand the things of the Spirit.
Specifically, that believers may understand the things God has prepared for those who love him, that we may understand what God has freely given us (not get what God freely offers), and make judgements about spiritual matters. " I Jn 2:27 shows how the Spirit helps teach us all things. Rom 8:14-16 shows how the Spirit illuminates the believers relationship as a child of God. Gal 5:16-26 shows how walking by the Spirit guards us against the desires of the flesh. Etc.
Again, nothing in the passage mandates that Spiritual regeneration precedes faith, as it is about the Spiritual discernment we gain once the Spirit resides in us. Unbelievers do not have that understanding of spiritual things.
