This is not my opinion.
1 Cor 2:14 says:
"But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned."
And the Lord Jesus Christ said this as well, in
John 3:3-8:
3 "Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
4 Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born?
5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
7 Marvel not that I said unto thee, Ye must be born again.
8 The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit."
Only God can reveal the truth to a sinner, and cause him to "see" what he would not otherwise be able to see in his natural state. And God does that under the preaching of the gospel.
(1 Cor 1:21; Rom 10:9-17)
The gospel is how Christ died for the sins of a particular people, according to the Scriptures. And how he was buried for three days and rose again, and ascended to heaven, according to the Scriptures.
(1 Cor 15:3)
That is, according to what all of the prophets in the Old Testament said he would do. He fulfilled all of that which was written of him, and he saved his people from all of their sins.
(Is 53; Matt 1:21!)
Christ came to this world, not to make salvation possible, but to actually accomplish salvation for those who were given to him by his Father before the world was.
(John 10:1-30; John 17:9) And that's what he did!
He actually bore the sins of his people in his own body on that cursed tree. And he shed his own blood to make an atonement for all of their sins, and God accepted it!
(Gal 3:13; 2 Cor 5:21; 1 Pet 3:18; Heb 9:12, ....etc)
And all those for whom Christ shed his blood and died, will not be left in their natural state, but will be raised from spiritual death to life, by the power of God, under the preaching of the gospel.
The Apostle Paul said,
"For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek." --
Rom 1:16
It is under the preaching of the gospel of Christ, that God sends his Spirit to enlighten the minds of his chosen people, and makes them to know, that they are, in fact, the children of God!
(Rom 8:15-16)
And God could have chosen whatever means he pleased to do that, but he chose the instrument of preaching. And it is only by God-given faith in Christ that any sinner can be saved.
(1 Tim 2:5; Rom 5:19-26)
This is why its so crucial to preach this gospel. The eternal souls of countless people will either go to hell for eternity or be reconciled to God through faith in Christ.
That is my concern, and that's why I do this. I don't earn any points with God for doing it. My whole salvation was accomplished by Christ. I only do this out of gratitude.
Well, there's a lot more to say, but I'll wait for your response.
Hopefully, Skarekrow won't rain on this parade. (I won't hold my breath.)
In any case, I pray that the Lord may be pleased to give you saving faith.
