You need to re-read Rom 11 and NOT spiritualize your understanding of it.
I have read it, studied it, it is you who appears to lack understanding of it. And Spiritualize, I spiritualize whatever Paul does. He knows more about the scripture than you and better qualified to determine what is spiritualized than you..
As to Cornelius, he was indeed a Gentile - a "god fearer."
That's right, of which no man by nature is according to scripture Rom 3:18
There is no fear of God before their eyes.Only those given a New Heart Fear God Jer 32:39-49
And I will give them one heart, and one way, that they may fear me for ever, for the good of them, and of their children after them:
And I will make an everlasting covenant with them, that I will not turn away from them, to do them good; but I will put my fear in their hearts, that they shall not depart from me.
Now, ethnic jews who are not born again, they have no relationship with God whatsoever Rom 9:8
8That is,
They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.
It does not matter what the talmud says either..
