The Jewish people are God's chosen people. In a world where there is increasing anti-Semitism, God is still in control. There is absolutely no evidence in the Bible where God rejects the Jewish people as His chosen people. There is no evidence where God is for anti-Semitism. In fact, the roots of Christianity is in Judaism. In the Book of Exodus, the same God that Christians worshipped the last 2000 years is the exact same God as the "Lord God of the Hebrews" (Exodus 3:18). The Bible was written by men and inspired by God thousands of years before Christianity. The Jews were held in captivity by the Egyptians for over 400 years. God constantly reminded the Jewish people, who were called Israelites in the Old Testament of their freedom from slavery. He was the same God that commanded the people to worship Him and obey all of His commandments and walk in His judgements. Even though God's people has disobeyed the Lord, they have been forgiven by Him after they repented and returned to Him. They are God's people by covenant. To Abram (Abraham), He said that He will make of him a great nation. (Genesis 12:2) He has also said that He will bless those who bless them and curse those that curse Israel. (Gen. 12:3) Throughout history, every nation that has oppressed or cursed the Jewish people are either no longer in existence or have had to suffer various consequences as a result. Two examples that come to mind are Germany and ancient Egypt.
While it is true that many of the Jewish people have rejected Jesus, there is never any excuse for bigotry and anti-Semitism. Many of the first Christian believers, all 12 disciples, the writers of the Bible, and Jesus Himself are all Jews. Paul, a Jew, wrote most of the entire New Testament or some of the books were based on His letters. "Salvation is of the Jews" (John 4:22). Jesus came to save the Jewish people. He is still the Messiah of the Jewish people. Romans 1:16 says that "It is the power of God unto salvation to the Jew first, then to the Gentile."
The birth and ministry of the Messiah has been prophesied in the Old Testament books of Psalms, Isaiah, and Zechariah. Isaiah 45:17 says, " [But] Israel shall be saved in the LORD with an everlasting salvation: ye shall not be ashamed nor confounded world without end." Israel will always be God's chosen people. In Revelation 7:4-8, 144,000 Jewish will have the seals of God written on their foreheads. God will not break His covenant with the Jewish people, nor will He. In Isaiah 46: 13, Israel is "my glory". In Israel 49:3, Israel is God's servant, in whom they will be glorified. Isaiah 49:6 also says, "And he said, It is a light thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth." Do not believe the lies that God is not the God of the Jewish people or it is okay to hate them because "they killed Jesus."
