There is no change. They are irrevocable. Once God uttered it, it would be carried through. Regardless of men, He would work it out so that the gifts, the calling, and the promises that He made to Israel are met.

God has a commitment to Israel—and thus us—because of the obedience of one man, Abraham. We are reaping the benefits of the good Abraham sowed almost four thousand years ago because God is faithful to His promises!

Little Things Count!
Man cannot "find" God; only God can initiate a calling. The world, including most of physical Israel, is consigned to unbelief until later in God's plan, yet most modern Israelites would say they know God or believe in Him. Romans 10:12-15 describes how God generally introduces people to Himself, though they may suppose they initiated contact with Him by "calling on the name of the Lord." Men must hear of Him through a preacher - and one whom God has sent, not one that is self-proclaimed.

Basic Doctrines: Faith Toward God
God's mind is absolutely undivided. In practical application, this means that His sovereignty can never be separated from His love; His grace cannot be separated from His omniscience; His judgment cannot be separated from either His mercy or His wrath. God is absolutely constant because His faithful providence cannot be separated from any other of His attributes. God is whole and complete. Under every circumstance, He is never confused or uncertain about what to do. He is always headed in the same direction, which is to complete His purpose.
It is absolutely impossible for Him to do anything that is not wise and at the same time loving. It is He who tells us how to live and how to be like Him. What God is has awesome ramifications for us because we are so different, and He wants us to be like Him, to be one with Him, to be whole, to be complete, to be undivided in mind like Him.
There are problems here because becoming this way requires a measure of cooperation from us. Compared to God, our mind is all over the place, and thus we are so easily distracted from our focus.

The good news comes in two parts. First, God has not put Israel so far away that it has no hope of salvation. Paul says plainly, "So all Israel will be saved." He is very positive that the vast majority of Israelites will enter God's Kingdom. Peter says in II Peter 3:9 that God "is not willing that any should perish but that all [all humanity, including Israel] should come to repentance."
Second, because of what Israel experienced—and yes, because they failed—the called of God, Christians, have been given the opportunity for salvation now as the firstfruits. God knew all along that Israel would fail; it was part of His plan to create a historical record of a physical people attempting to keep His covenant. Among other things, He desired a people—Israel—to show His regenerated children the absolute futility of life without Him, even if it is lived under the best circumstances.
God loves Israel, so He did not commit them to eternal disobedience and condemnation. Very few of them have lost their opportunity for salvation. He has simply put them aside for the time being. Other places in the Bible explain that God will open salvation to them later, when conditions will be even better for them (see Ezekiel 37:1-14; Revelation 20:12-13). As Paul says in Romans 11:31, the salvation of Christians will eventually work out for the benefit of the Israelites: They will also obtain mercy (see also verses 11-15, 23-25).
Nevertheless, due to their being "broken off" from the vine (verse 17), a place has been made for others to be "grafted in." We should note that the vine's roots and trunk, as it were, were never rejected—just some of the branches. This means that God's Kingdom is still in large part an Israelite Kingdom! It is still rooted in the Patriarchs, the prophets, the teachings and promises, the house of David, the Twelve Tribes, and the most important of all Israelites, Jesus Christ of Nazareth.
No, Israel, though blinded to God's way for now, remains a vital part of God's plan of salvation!
