Jesus died for your sins, whether you were born an Israelite or not. That all Israel will be saved is speaking of Israel yes, God's people. Does this take into account that we don't know all who will be saved? I believe yes. Well, obviously some from Israel now can be said to have come to Christ. I don't know how to speak about it though, whether this is correct to interpret it as true prophecy from the following. There are different views on the phrase, "(and so) all Israel will be saved".Unt,
There is pretty good evidence that almost no one today in israel knows their tribal descendency. There are also only about 8% evangelicals. About the same % are orthodox but the majority are agnostic or NYC liberals.
It is entirely possible that the orthodox will resurrect Judaism enough to practice the whole worship system again, which would bring us back to the eve of the New Testament period, right?
So I don't see very much the same. Northwye is quite right that 11:26's "all" can't be the ethnos; it is the "Israel" (or remnant, or elect, or Abraham' seed) Paul has been referring to since ch 2, again in ch 9. In 11, granted, there are several contrasts between ethnos Israel and the nations, but anytime you limit a group that's moving through history and say at one future moment that "all" of it will be saved, you have actually qualified that "all" quite a bit.
Then, look carefully at how Isiaiah is quoted. It is all current. Those things are fulfilled for Paul: the Redeemer came, the sin as debt is taken away, the new covenant is operating. 11:30 solidifies with God only doing things through and upon Christ, whether in mercy or wrath. The same standard for all manking.
Romans 11:23-27 NASB - 23 And they also, if they do not continue in their unbelief, will be grafted in, for God is able to graft them in again. 24 For if you were cut off from what is by nature a wild olive tree, and were grafted contrary to nature into a cultivated olive tree, how much more will these who are the natural branches be grafted into their own olive tree? 25 For I do not want you, brethren, to be uninformed of this mystery--so that you will not be wise in your own estimation--that a partial hardening has happened to Israel until the fullness of the Gentiles has come in; 26 and so all Israel will be saved; just as it is written, "THE DELIVERER WILL COME FROM ZION, HE WILL REMOVE UNGODLINESS FROM JACOB." 27 "THIS IS MY COVENANT WITH THEM, WHEN I TAKE AWAY THEIR SINS."
I don't know whether or not it is right to say we who have believed are now of Israel.
Ephesians 2:12 NASB - 12 remember that you were at that time separate from Christ, excluded from the commonwealth of Israel, and strangers to the covenants of promise, having no hope and without God in the world.
