Because there were Jews who did believe in Jesus as their Messiah. Most of the apostles were of Israel. There are many Jewish believers, who after receiving Christ become apart of the church. Those of Israel who did not receive Jesus as Messiah belong to unbelieving Israel. It is that last generation of unbelieving Israel that God is going to deal with during that last seven years in fulfillment of the seventy sevens that were decreed upon them.
Every Jew who has received Jesus as Messiah from the on-set of the church until the resurrection, will be included in the resurrection as belonging to church, as well as those believing Jews who are alive at the time of the resurrection will be changed and caught up and that because they are considered to be apart of the church.
The Church = Jew and Gentiles
Israel = Unbelieving Israel

So what has happened to "glory, honour and peace to the Jew first"? where is it?
