Israel did embrace Jesus as the Messiah. God rejected those who did not and grafted believing gentiles into their place.
Once and for all:
THE CHURCH IS NOT ISRAEL! The Church is a spiritual kingdom--Jesus said so--it is a blessing for ALL nations. Israel is a mortal national entity. Israel has never yet occupied all of the geography outlined in the Book of Ezekiel. It will when the physical Kingdom of Israel is restored. It is unthinkable that the irrevocable promises of the prophecies of the latter prophets (which did NOT depend on obedience) would be overturned.
Here is a teaching about the Kingdom of Israel which is seen from Matthew's point of view. It deals with prophecy from Micah that we Christians love to quote:
"In Matthew 2 we have recorded the response of the Jewish leaders to the question of Herod, who "inquired of them where the Christ (Messiah) should be born" (v. 4). The response was, 'In Bethlehem of Judea'; and in support, Micah 5:2 is cited, which says that from Bethlehem would 'come a Governor, that shall rule My people Israel' (vv. 5,6).
These words show very clearly that Jesus Christ is to rule the nation of Israel. However, anyone wishing to object to this could point out that it was the Jewish leaders who cited the prophecy, and they were mistaken about the true role of the Messiah they looked for. In reply to this...
...The angelic revelation quoted above from Luke 1:32,33 links perfectly with this, confirming our understanding that
Micah 5:2 refers to the restored Kingdom of Israel, and that this promised restoration will be fulfilled literally.
