I found a website that uses the common Greek translation of the Bible and cross references it with Strong's.
I think if we accept what Paul wrote about the inability of our natural mind being able to understand the things of God, because to the natural mind sees it as foolishness we have but to realize and as God tells us , only God's Holy Spirit could change this.
I think if we put all that together from God's words that inform us of our condition of natural mind, we may realize those of us who have faith in God and Jesus Christ do so because God did what only his Holy Spirit could do by and through his grace.
He bestowed faith and salvation.
Because when the natural mind cannot understand the things of God,which naturally includes coming to have faith in God, because to the natural mind that is foolishness to us? Why not? God tells us.
It is because the things of God, like the Gospel, God's good news, are spiritually discerned.

How then does that fact change?
God. As God tells us.
Below is English common Greek, known as Koin Greek, chapter.

We are saved by God's grace. When our natural minds are incapable of understanding the things of God , that Salvation must include giving us the capacity for faith in that which saved. Because,as God knows and says, our natural mind can I lay understand,accept the things of God, through intetcession of his Holy Spirit.
And we know this because Jesus said, the Spirit of Truth, the Holy Spirit, cannot be seen or received by the world. Those in their worldly, natural mind. John 14:17
Those are my thoughts anyway.
