(That is a side issue, as some don't even want to hear anything about God.
Their "predication" is non-existent.)
That's a part of not hearing. And you didn't answer my questions about not being able to hear spiritually.
You have the cart in front of the horse.
Nope. First saved/born again, and from that, faith, spiritual hearing/spiritual discernment, etc comes. Salvation brings faith and knowledge; faith and knowledge doesn't bring salvation.
The natural men Paul writes of are those who refused the gospel.
And, he is writing to natural men who are no longer "natural".
Paul is writing to the converted about the unconverted.
If there were spiritual men on earth before their conversion, there would have been no need for Jesus, or Paul.
What could Jesus provide that they didn't already have, being spiritual men?
All unsaved refuse the gospel. They refuse it because they were not given, nor do they possess, spiritual discernment -
that was my whole point.
Didn't you read the " neither can he know
them, because they are spiritually discerned", part of the verse?
Of course, Paul was writing to those saved, the unsaved, being natural man, could/would not be able to
comprehend what Paul was telling them. He was providing instruction and edification to those already saved so that
they gain an understanding of their salvation. So, unless saved, natural man cannot understand.
Here, these verses explain it further. They tell us that unless someone is first born again, they do not have a spiritual mind that can perceive the things of God, and not perceiving the things of God, they will not believe in true gospel, nor desire salvation on the basis of the gospel. Therefore, only certain people - those who are given that understanding by God - can truly believe in it. As we are informed in Luk 1:77 (below), a true knowledge of salvation comes only to those whom Christ died for, by which, their sins are remitted, and they gain spiritual discernment - salvation first, discernment after.
In other words, no one can even know the true salvation unless and until their sins are first forgiven. Notice
the "unto his people". That means Christ has a certain people, and it is they alone who's sins become remitted, so remittance being only unto them, is not given to/for everyone.
[1Co 2:12 KJV] 12 Now we have received, not the spirit of the world,
but the spirit which is of God;
that we might know the things that are freely given to us of God.
In is impossible for someone to truly know salvation until and unless their sins are first remitted.
[Luk 1:77 KJV] 77
To give knowledge of salvation unto his people by the remission of their sins,
