It is universal Christian teaching among Catholics, East Orthodoxy, and all Protestant denominations founded prior to John Darby that the Jews who followed their Messiah, and those Gentiles who joined them, were the sole inheritors of the Abrahamic blessings. Any who reject Christ are "broken off" from the tree of Israel until they return to the fold by faith. DNA without a reciprocating faithfulness to the Covenant counts for nothing.
Prophesies that give the land the Jews and predict the reestablishment of Israel may be opaque to you, but they are clear to me and many others. Moreover, the Gospels and the Epistles are the most important parts of the Bible for Christians, but those sections are not the only parts. The Bible for Christians should be as seamless as Jesus cloak.
Re-read the prophesy at the top of this thread and the worldly interpretation which directly contradicts Romans 11, Matthew 3:9, Luke 3:8, John 8:33, etc., etc., etc.
Pardon me if I am misreading you comment here, I have not paid attention to your view up till now, but I sense you dont believe that Israel (Jews) are still Gods chosen people and will once again be dealt with on an individual (as a nation) basis during the Tribulation period.
Romans 11 specifically deals with that and explicitly says that the Jews, ie Israel, will be again dealt with as it says until the fullness of the Gentiles be come in. Once God determines that the end of the time for the Gentiles has come He will again, for a period of seven years, deal with the Jews as a nation.
