Okay we’ll ask yourself how is the only way all Israel will be saved?
They will believe in Jesus.
It can’t be ethical Israel because we both know that they all are not and were not saved
Only the true church are and all are saved
Don't you believe God can change hearts?
Ezekiel 11
17 Therefore say, 'Thus says the Lord GOD: "I will gather you from the peoples, assemble you from the countries where you have been scattered, and I will give you the land of Israel." '
And He did.
18 And they will go there, and they will take away all its detestable things and all its abominations from there.
19 Then I will give them one heart, and I will put a new spirit within them, and take the stony heart out of their flesh, and give them a heart of flesh, 20 that they may walk in My statutes and keep My judgments and do them; and
they shall be My people, and I will be their God.
And they will!
