In your addled mind that passage (and evidenty every other passage from Genesis to Revelation) means that Israel has been forever kicked to the curb....but in Isaac shall thy seed be called. That is, they which are of the flesh these are not the children of God...

That's about the size of it buddy.
And never forget: team Satan would like nothing better than to see exactly that happen.
Israel being utterly forsaken and condemned by God that is.
So you are in good company.
BTW........replacement theology is a heresy. Israel being forsaken by God is a heresy too. Just thought you might want to know that. But of course I could be wrong.
