I certainly hope not. But from your question I see that you still fail to understand just who the covenant nation of Israel is.
Before I give up, here are some questions for you. Maybe these will help clarify things:
Spiritually by virtue of the fact that he has accepted Christ as Savior. The spiritual child of Abraham is not the same as the ethnic, physical seed of Abraham, nor does the spiritual child of Abraham replace the ethnic, physical seed of Abraham.
Is a jewish non believer a child of Abraham?
A Jewish believer is both a spiritual child of Abraham and the ethnic, physical seed of Abraham.
In John 8:39ff are these children of Abraham?
They are the ethnic, physical seed of Abraham but not the spiritual child of Abraham because they rejected Christ as Savior.
Is a gentile believer a member of the commonwealth of Israel?
A Gentile believer is part of the spiritual Israel, in that they became adopted into the family of God by faith in Jesus Christ which was offered first to the Jew and meant for the Jews. They are not part of the literal nation of Israel, as they are not the physical seed of Abraham, and are not included in the promises that God made to the ethnic, physical seed of Abraham.
Why doesn't the current "nation of Israel" perform the daily sacrifices?
Actually, the Jews have resumed animal sacrifice and have been since around 2008.
However, because their temple was destroyed in 70AD, they were dispersed throughout the world, and have not rebuilt their temple.
We know from Daniel 9:27 that the third Jewish temple will be rebuilt and sacrifices will be carried on in that temple because midway through the Tribulation, the Antichrist puts a stop to it, stands in the temple, and declares himself to be God:
Then he shall confirm a covenant with many for one week; but in the middle of the week he shall bring an end to sacrifice and offering. And on the wing of abomination shall be one who makes desolate, even until the consummation, which is determined, is poured out on the desolate."
So while limited sacrifices are happening now, shortly the temple will be rebuilt and the sacrifices in the temple will resume.
Would the reinstatement of the daily sacrifice by the "nation of Israel" be ok?
It's not "ok", however, when the Church age ends at the Rapture, God will turn His attention back to His people and will complete the last seven years of Daniel's prophecy of the 70 weeks. The Jews will pick up where they left off, their temple will be rebuilt, and they will have animal sacrifices.
This will end at the end of the Tribulation when the remnant of surviving Jews come to faith in Jesus as their Messiah and are given all that God has promised them and are restored in a covenant relationship with God.
It doesn't matter what our opinion is, our opinions can't be more meaningless. What God has said is going to happen will happen, and there is nothing anyone can do about it.
Who are the elect?
The word "elect" is used different times in Scripture and refers to different groups of believers. Both in Hebrew and Greek the word for elect means chosen and is used in a number of ways. It refers to the Messiah in Isaiah 42:1, Israel in Isaiah 45:4, the Church in Romans 8:33, and tribulation believers in Matt. 24:22. In Mark 13:27 Old Testament saints, the raptured Church, and Tribulation believers are all included as the elect.
Depending on the context in which the word is used in any given passage will reveal which group the word "elect" is referring to.
