"Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel: Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called. That 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." - Rom 9:6-8 KJV
"Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ. [...] And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise." - Gal 3:16&29 KJV
"What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded." - Rom 11:7 KJV
"And they also, if they abide not still in unbelief, shall be grafted in: for God is able to graft them in again." - Rom 11:23 KJV
"Esaias also crieth concerning Israel, Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved:" - Rom 9:27 KJV
Nowhere in scripture does it say that all people of Israel would be saved. Scripture states that very few of Israel will be saved. And still, nowhere in this does scripture say that the "nation of Israel" is chosen.

All of those that are a part of Israel/Jacob are eternally saved (delivered). The nation of Israel is not the same as Israel/Jacob. Israel/Jacob are made up of every kindred, and tongue, and people, and nation. (Rev 5:9).
The house of Israel/Jacob turned away from God, but God left in the midst of them a poor and afflicted people, which was a remnant of the house of Israel/Jacob.
Zeph 3:11-13 - In that day shalt thou not be ashamed for all thy doings, wherein thou (the house of Israel/Jacob) has transgressed against me, for then I will take away out of the midst of the them that rejoice in thy pride, and thou shalt no more be hauty because of my holy mountain. I will also leave in the midst of thee an afflicted and ;poor people, and they shall trust in the name of the LORD. The remnant of Israel/Jacob shall not do inqity, nor speak lies, neither shall a deceitful tongue be found in their mouth; for they shall feed and lie down, and none shall make them afraid.
