God indeed will judge Jews by a different measure. Be glad of that. God's judgement on Israel is severe. That's why 6 million perished under Nazi rule.
When it comes to salvation, it is true that everyone is saved the same way. And all will be judged as sinners or saints without exception. Lord Jesus is returning to Jerusalem, to the Mount of Olives, not Washington or Los Angeles. He will rule and reign from Mount Zion, not London or Paris.
God's covenant with literal Israel has not changed. 1948 proved that. Israel exists now only by the power of God. Israel is a nation of 8 million Jews surrounded by 400 million hostile Muslims. They could raise armies that would flood Israel if they chose to. Why do they not? God protects Israel.
God will remove His protection during the Great Tribulation. Nations from the North will invade Israel, but God will step in to to destroy those armies. The millennial reign of Christ will begin and Satan cast into the bottomless pit.
Sure, most Jews rejected Jesus and Israel paid a terrible price. However, it was to Israel and the Jews that Jesus came. It was to Jews that He gave the responsibility to preach the gospel. God's plan and purpose for Israel has never changed and God's will shall be done. Jeremiah 33 includes this declaration
Behold, the days are coming, declares the LORD,when I will fulfill the gracious promise that I have spoken to the house of Israel
and the house of Judah. In those days and at that time I will cause to sprout for David a righteous Branch, and He will administer justice and righteousness in the land. In those days Judah will be saved, and Jerusalem will dwell securely, and this is the name by which it will be called:The LORD Our Righteousness.
Read all of Jeremiah 33. God's plan for Israel will be fulfilled.
Isaiah alone contains so very much of the "IN THAT DAY" future prophecy for Israel and Jerusalem.
Massive quantities. Why the denials by the replacement theology types? Frankly its deeply concerning if not outright scary.
Absolutely NONE of this has happened yet in all of recorded history.
