What is it that Israel has done that has caused YHWH to cast them off?
They only murdered his son…the one he sent to save them….
What has Israel done in their entire history but cause offense to the one who chose them?
What did God say to Moses when he was in the mountain….Jehovah informed him that the people had turned to idolatry and he said:
“Now let me be, that my anger may blaze against them and I may exterminate them, and let me make youinto a great nation.”
”Exterminate” is a very strong word, indicating the depth of his displeasure with his people….but this was just the start of their rebelliousness. We actually learn more about God through his discipline to Israel than in his blessings. They teach us through their failings what God required of his people and what he will not tolerate.
Because God said that wasn't going to happen. You seem busy looking at Israel's behavior, meanwhile, you overlook the promise of God.
What was the promise of God to Israel? And were the fleshly Jews ever a good example of obedience?
Did they ever learn from their mistakes or did they just continue to be that “stiff necked” people they had always been throughout their generations?
What spiritual condition did Jesus find his nation in, when he presented himself for baptism?
During his entire ministry, exclusively to the Jews, he did not have a good thing to say about the Jewish leadership, who turned the people against their own Messiah because he didn’t fulfill their expectations about who the Messiah would be and what he would do. Read Matt ch 23.
The literal nation has never changed in their attitude towards Christianity, and so it was Paul who told us that God chose a new “Israel”….not a nation born of the flesh, but one united nation of people from every nation, who would make up what he called
“the Israel of God”. (Gal 6:16)
It was Paul who also said of this people that the definition of a “Jew” had changed…
“He is not a Jew who is one on the outside, nor is circumcision that which is on the outside upon the flesh. But he is a Jew who is one on the inside, and his circumcision is that of the heart by spirit, and not by a written code.”
Consequently, after expressing sorrow because his Jewish brothers according to the flesh came short of their privileges regarding the
“adoption as sons and the glory and the covenants,” Paul says:
“However, it is not as though the word of God had failed. For not all who spring from Israel are really ‘Israel.’ Neither because they are Abraham’s seed [according to the flesh] are they all children, but: ‘What will be called “your seed” will be through Isaac.’ That is, the children in the flesh are not really the children of God, but the children by the promise are counted as the seed.” (Rom 2:28-29; Rom 9:6-8)
Spiritual “Israel” are the ones who follow the Christ and who are obedient to his God and Father….
It is the devil who has people imagining that the blood spilling literal nation of Israel are still servants of the true God, but by their conduct, they prove the opposite. If God was backing Israel, they would have no need to rely on foreign nations to support them….the very thing their forefathers did which earned God’s condemnation.
Jesus told the Samaritan woman at the well that the place of worship is not important. God’s worship would no longer be confined to a literal place on earth, now polluted with blood.
He said:
“The hour is coming when neither on this mountain nor in Jerusalem will you worship the Father.”
Then he told her: “The hour is coming, and it is now, when the true worshippers will worship the Father with spirit and truth, for indeed, the Father is looking for ones like these to worship him.” (John 4:21, 23, 24)
Jesus lamented over his efforts to teach his people the truth….and the fact that his people were incorrigible.
”Jerusalem, Jerusalem, the killer of the prophets and stoner of those sent to her—how often I wanted to gather your children together the way a hen gathers her chicks under her wings! But you did not want it. 38 Look! Your house is abandoned to you. 39 For I say to you, you will by no means see me from now until you say, ‘Blessed is the one who comes in Jehovah’s name!’” He was quoting Psalm 118:26, which contains the Tetragrammaton.
In the last 2000 years, has natural Israel ever blessed the one who came ‘in the name of their God’…a name they had long since refused to utter….but there was never a command from Jehovah to ever do so. It was yet another act of disobedience. (Exodus 3:15)
You are looking in the wrong place for the “Israel of God”…..fleshly Israel was abandoned many centuries ago.
