The plan of salvation was conceived by God ... the Father, Son and Holy Spirit before the creation of the world, and has been carried forth continuously since creation and through the Jews and Israel, as said in God’s Word from Genesis through Revelation, and leaving nothing out in any of the Old Testament or New Testament ... with much of the Old Testament’s promises to Israel being fulfilled at the future time of Israel being the shining light to the world as God intended. There will still be those who will be saved, in that future one-world government, when Israel is the ruling nation over all other nations, and when Ezekiel’s Temple is built at that future time ... so the work of Salvation will still go on at that time, but with Israel being in its rightful place in the world, finally.
But as a side note here, outside of what God says in the Old and New Testaments, I’m not sure how Judaism got into this. I know I didn’t mention it. I don’t call the Old Testament Judaism and the New Testament Christianity ... I call the entire a Bible from beginning to end, God’s plan of Salvation, through the Jews, with the Messiah of Israel being the only way for that salvation individually.

“I’m not sure how Judaism got into this.”
Judaism is the state religion of Israel. A tenet of Judaism, the only one I’m familiar with, is a rejection of Christ. My point is that a nation that rejects Christ, from its inception, is not being used in the plan of salvation. God loves Jews, not because they are Jews, but because they are humans.
