". . . So then faith
cometh by hearing, and hearing by the
word of God.
But I say, Have they not heard? Yes verily,
their sound went into all the earth, and their words unto the ends of the world." -- Romans 10:17-18, ", , , Their line is gone out through all the earth, and their words to the end of the world. . . ." -- Psalms 19:4.
Your leaving out the entire context though, look at v16 and v20
16
But they have not all obeyed the gospel. For Isaiah says, “Lord, who has believed our report?” 17 So then faith comes by hearing, and hearing by the word of God.
18 But I say, have they not heard? Yes indeed:
“Their sound has gone out to all the earth,
And their words to the ends of the world.”
19 But I say, did Israel not know? First Moses says:
“I will provoke you to jealousy by those who are not a nation,
I will move you to anger by a foolish nation.”
20 But Isaiah is very bold and says:
“I was found by those who did not seek Me;
I was made manifest to those who did not ask for Me.”
21 But to Israel he says:
“All day long I have stretched out My hands
To a disobedient and contrary people.”
Then see what the gospel writer has to say!
What your quoting as support for your view is the exact opposite.
It has to do with hardening of the Jews whom God has blinded so that they could not believe.
So if your honest you will see your folly here.
Others reading here will see it too.
Conversely, the phrase to whom has the arm of the Lord been revealed, has to do with God being found by those who did not seek for me and those who did not ask for me. Pointing to God changing their hearts not according to their natural will which is to reject God.
You treat all this as something natural, as if a naturally minded man can receive the things of God.
By natural revelation the world is condemned, read Romans 1 !!
As your opposed to John 12's interpretation about these things, you need to change your mind about all of these things.
John 12
Who Has Believed Our Report?
37 But although He had done so many signs before them, they did not believe in Him, 38 that the word of Isaiah the prophet might be fulfilled, which he spoke:
“Lord, who has believed our report?
And to whom has the arm of the Lord been revealed?”
39 Therefore they could not believe, because Isaiah said again:
40 “He has blinded their eyes and hardened their hearts,
Lest they should see with their eyes,
Lest they should understand with their hearts and turn,
So that I should heal them.”
41 These things Isaiah said [f]when he saw His glory and spoke of Him.
