Gosh, once i was a Gentile!
I am sorry to give the impression that there were no saved non-Jews in the OT, i was only speaking generally.
My point is that salvation comes to those God personally reveals His saving Word in. Consider this passage from 2nd Corinthians 4:
And even if our gospel is veiled, it is veiled to those who are perishing, in whose case the god of this world has blinded the minds of the unbelieving so that they might not see the light of the gospel of the glory of Christ, who is the image of God. For we do not preach ourselves but Christ Jesus as Lord, and ourselves as your bond-servants for Jesus’ sake. For God, who said, “Light shall shine out of darkness,” is the One who has shone in our hearts to give the Light of the knowledge of the glory of God in the face of Christ.
We preach Christ Jesus as Lord to many but to whomever we preach to they get saved even as we did: God, who said, “Light shall shine out of darkness,” is the One who has shone in our hearts to give the Light of the knowledge of the glory of God in the face of Christ. So likewise they get saved when He shines in their hearts, giving them the Light of the knowledge of the glory of God in the face of Jesus the Messiah.
If He does not, they remain blinded still to that glory of Christ, the Gospel truth, and to the reality that only Jesus saves.
Likewise we read that Abraham was called by God and given a promise and he believed.
The knowledge of the true one was not lost, for who preached to Abraham?
But as for all other men we read:
What then? Are we better than they? Not at all; for we have already charged that both Jews and Greeks are all under sin; as it is written,
“There is none righteous, not even one;
There is none who understands,
There is none who seeks for God;
All have turned aside, together they have become useless;
There is none who does good,
There is not even one.”
“Their throat is an open grave,
With their tongues they keep deceiving,”
“The poison of asps is under their lips”;
“Whose mouth is full of cursing and bitterness”;
“Their feet are swift to shed blood,
Destruction and misery are in their paths,
And the path of peace they have not known.”
“There is no fear of God before their eyes.”
A bleak picture is painted, and we read on…
Now we know that whatever the Law says, it speaks to those who are under the Law, so that every mouth may be closed and all the world may become accountable to God; because by the works of the Law no flesh will be justified in His sight; for through the Law comes the knowledge of sin. But now apart from the Law the righteousness of God has been manifested, being witnessed by the Law and the Prophets,..
Now even you admit that such knowledge was rare. And that my friend is the point. God kept Himself hid, His salvific knowledge rare. Even the outpouring on the Israelis was a small thing for we read in Deut. 7:
For you are a holy people to the Lord your God; the Lord your God has chosen you to be a people for His own possession out of all the peoples who are on the face of the earth. “The Lord did not set His love on you nor choose you because you were more in number than any of the peoples, for you were the fewest of all peoples, but because the Lord loved you and kept the oath which He swore to your forefathers, the Lord brought you out by a mighty hand and redeemed you from the house of slavery, from the hand of Pharaoh king of Egypt.
But it was His chosen servant Israel otherwise known as Jesus that Isaiah speaks about in the passage you brought forth. But even then we see that salvation only comes to a remnant of the people in every land. Even in the USA, once maybe the most Christian of nations, do we see that God is not saving the most only the many.
i dunno, maybe you think He is trying and failing, after all He has to work with us imperfect battered vessels. i dunno how you see God, but looking at the reality of life across this globe, if His goal is to save even half, He is falling way short. And 56 million people die every year! [http://www.hebrew4christians.com/About_HFC/Death_Rate/death_rate.html] And looking at other tables i can’t see how half of those are Christians. Which means He is losing ground… fast! Over 2.4 million die in the USA every year, and somehow i doubt that even half of those are believers.
Much disagreement between us brothers comes down to how we see God. Are you letting ideology usurp theology? Truth is truth. Is your God winning or losing?
