I agree, but we have to work in real time and in this world. I have news for you: the Church was rejected by the vassmajority of the Jews. It's survival was not there.
The survival of The Church Universal has always been God's business.
Of course, the OT & NT are/were clear that the house of Israel would reject The Messiah . . . and He would be a deliverer for all mankind . . . then . . . in the closing acts of the play . . . the House of Israel would again recognize their true Messiah . . . stay tuned . . . the play continues.
It was no surprise to God that the House of Israel would, on the whole, reject it's Messiah.
