The Jewish people have enough fault in the death of Christ. It is not something popular in Christian circles. In some ways Israel has become an idol to parts of the Church and that colors the way she is seen in the End Times. The promise that all Israel will be saved is distorted because they don’t see the promise of all Israel being destroyed. How can both be true? The key is that not all Israel is Israel. What the heck does that mean? A Jew is not a Jew if He is one only in the flesh. The Lord told Israel they needed to be circumcised in the heart a picture of spiritual rebirth without it the Lord God said Israel was headed for the same judgment as the Gentile nations.
51 Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did, so do ye.
52 Which of the prophets have not your fathers persecuted? and they have slain them which shewed before of the coming of the Just One; of whom ye have been now the betrayers and murderers:
He basically accused their fathers, and themselves, of murdering whoever they dislike and tell them things they don't want to hear, and it accumulated to killing the Son of God himself.
