Perhaps you should read the old testament, specifically Exodus.Nowhere does Scripture ever speak of a Jewish covenant people on earth, much less entering the kingdom of Christ. It's the heretic construct of a made up Goyim/Gentile theology.
There has never been a 'Jewish covenant people'. At least, not with the God of Israel, because He has never had a covenant people by natural birth, but only through faith. The OT covenant was never a Hebrew, Israeli, nor Jewish covenant, but only a covenant of faith in circumcision and law.
God's covenant has never been by natural birth. And so no all naturally born of Israel, are the Israel of God by faith. And Paul is more bold, in declaring not all born Jews are not Jews with covenant of God by circumcision:
The gross error of Goyim/Gentile theology, is claiming the true God ever has a covenant with a people of 'special' natural birth: Theological eugenics. So that there is a 'Jewish covenant people' vs a 'Gentile covenant people'...
Exodus 19:3-6 Then Moses went up to God, and the Lord called to him from the mountain and said, “This is what you are to say to the descendants of Jacob and what you are to tell the people of Israel: 4 ‘You yourselves have seen what I did to Egypt, and how I carried you on eagles’ wings and brought you to myself. 5 Now if you obey me fully and keep my covenant, then out of all nations you will be my treasured possession. Although the whole earth is mine, 6 you will be for me a kingdom of priests and a holy nation.’ These are the words you are to speak to the Israelites.”
Exodus 24:6-8 Moses took half of the blood and put it in bowls, and the other half he splashed against the altar. 7 Then he took the Book of the Covenant and read it to the people. They responded, “We will do everything the Lord has said; we will obey.”
8 Moses then took the blood, sprinkled it on the people and said, “This is the blood of the covenant that the Lord has made with you in accordance with all these words.”
I suggest you rethink your position in light of these passages.
