Israel will be under a new covenant with God during the Millennium.
In the Church age, there is no distinction between Jew and Gentile when one believes.
Some think it ends all there.
But, in the future, during the Millennium, those on earth will once more have a distinction between the Jew and the Gentiles
There will be a distinction drawn for those alive on earth for the 1000 years.
The Church will have been resurrected and will have our home in heaven.
When possible, we are to protect the Jew out of respect for our Father's desire.
That is why Christians should show (when possible) a special guardianship for the Jews today.
When we are resurrected? Israel will have become once more a special nation of God's people on earth.
Not like the OT days. A new covenant will be lived by.
Israel shall be the place where Jesus will be seated on the Throne of David in Jerusalem, as King of those Jews.
Here's glimpse into what it shall be like in those days to come for Israel.
This is what the LORD Almighty says: “In those days ten people from all languages
and nations will take firm hold of one Jew by the hem of his robe and say,
‘Let us go with you, because we have heard that God is with you.’
Zechariah 8:23
In Contrast: We are the Church.
There is neither Jew nor Gentile for anyone who believes.
But, our Home is Heaven. Not earth during the Millennium.
Do not assume that God is done with His Chosen Jewish people.
For Jews living at that time will find their future home on the new earth.
For, God wants Jews to be alive for when He rules the New earth.
That is why Satan promotes and encourages antisemitism as to attempt to prevent that from ever happening.
It was why demon possessed Hitler wanted so badly to eliminate all Jews from the earth!
So...
Christians, we need to be careful when some begin to poke at the apple of God's eye!
