I fully agree, the Church Isnt the same as Ethnic Israel of the flesh
The Church is the Israel of God, children of the promised seed
They which are the children of the flesh (Jews) these are not the children of God
Romans 9:6-8KJV
6 Not as though the word of God hath taken none effect.
For they are not all Israel, which are of Israel:
7 Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called.
8 That is,
They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.
