Jesus made the two groups ONE.
You are badly mistaken.
Ephesians 2:14 For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility,
15 by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace,
There is NO difference between Jew and Gentile!
You are the one who is badly mistake.
He made individual Jew and Gentile one in a new humanity.
He didn't make them one in the nation of Israel, which is an ancient entity which GOD created long ago.
The body of Christ is new with individuals of all nations entering in. They are not entering into national Israel.
There is no difference between Jew and Gentile in the body of Christ, but there is a difference between national Israel and the body of Christ. These are two different creations of GOD.
National Israel is promised the land, the same land as always and with a King ruling from the throne of David, in that land.
The Body of Christ, the church, is not promised a land but are citizens of heaven.
The Bible has certain facts with distinctions.
But you put them all in a blender and mix them up.
