Jews heading to the millennium. If you want the body of Christ, go to Paul’s epistles.
I am sought of them that asked not for Me; I am found of them that sought Me not:
I said, Behold Me, behold Me, unto a nation that was not called by My name.
(Isaiah 6:1)
But I say, did not Israel know? First Moses saith, I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you. But Esaias is very bold, and saith, I was found of them that sought Me not; I was made manifest unto them that asked not after Me. But to Israel He saith, all day long I have stretched forth My hands unto a disobedient and gainsaying people.
(Romans 10:19-21)
that's 'a nation' singular in Isaiah, and Paul makes clear that He is not talking about Israel when He says 'a nation not called by My name'
Peter speaks of the same thing --
Which in time past were not a people, but are now the people of God:
which had not obtained mercy, but now have obtained mercy.
(1 Peter 2:10)
so how can he be speaking 'only' of Jews? were they never before a people?
