I agree Yeshua is the messiah. But Yeshua is also one and the same as YHWH in the old testament. Anyone who rejects Yeshua doesn’t know the Father, John 8:19.

But Romans 1:16 says salvation comes through Christ for the Jew first and also for the Greek.

Anyone can be grafted into Israel, (see also Roman’s) but to say Israel is done away with is just replacement theology.

It is sad though how many Jews reject Yeshua.
