This link you shared has a vast amount of resources because it’s an entire organization dedicated to demonstrating that Whites are God’s chosen people. I read several posts to get a sense of what their about.

The idea of Europe being God’s chosen people is fascinating to me and it can explain a lot. however I must point out scripture does clearly state Christ has come to save both Jew and Gentile as seen here:

John 10:16 ESV - And I have other sheep that are not of this fold. I must bring them also, and they will listen to my voice. So there will be one flock, one shepherd.

Colossians 3:11 ESV - Here there is not Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free; but Christ is all, and in all.

Acts 15:7-9 ESV - And after there had been much debate, Peter stood up and said to them, “Brothers, you know that in the early days God made a choice among you, that by my mouth the Gentiles should hear the word of the gospel and believe. And God, who knows the heart, bore witness to them, by giving them the Holy Spirit just as he did to us, and he made no distinction between us and them, having cleansed their hearts by faith.
