God is NOT willing that any should perish. From the beginning of the World. BEFORE the was a Jew or a Gentile, His "intent" was that the Gentiles should be fellowheirs, (with the Jew) and of the same body, and partakers of his promise in Christ by the gospel:
And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ.." (Eph.2:1-22; 3:1-12)
This is not "replacement theology"as some say. This God's Redemptive Purpose unfolding reconciling the Jew and Gentile together as saints. ONE NEW MAN
It is the Covenant that is crucial not your natural genealogy. The Israelite and the Stranger had to abide by the Covenant
