There has always been unjust antisemitism in the world or has the millions killed in WWII death camps been forgotten? To this day, there are people who hate the house of Judah from where the Jews come from and the only other that stands as witness on earth to the God of Abraham, Isaac, and Jacob besides the Christian.
There are many people who are Jewish, today, who worship and accept Jesus as the Messiah, and they are just as accepted as any other group of people into the fold of the Great Shepherd, Jesus.
The devil has hated the Jews for ages, as he knew that the "lion of Judah" and "King of Kings", Himself, would come through the seed of Jacob's son, Judah. He tried several times to prevent the birth of Messiah.
Someday, a remnant of both houses of Israel, along with their companions - the grafted in wild branches, will reunite under one King and leader. It is foretold they will inherit the land with Jesus as King for 1000 years or the last "day" where the earth finally enjoys a sabbath rest from war. Peace will reign Jesus' kingdom.
Jer 3:18 In those days the house of Judah will walk with the house of Israel, and they will come together from the land of the north to the land that I gave your fathers as an inheritance.
Eze 37:12 Therefore prophesy and say unto them, Thus saith the Lord GOD; Behold, O my people, I will open your graves, and cause you to come up out of your graves, and bring you into the land of Israel.
13 And ye shall know that I am the LORD, when I have opened your graves, O my people, and brought you up out of your graves,
14 And shall put my spirit in you, and ye shall live, and I shall place you in your own land: then shall ye know that I the LORD have spoken it, and performed it, saith the LORD.
Is.65:8 ¶ "But I will not destroy them all," says the LORD. "For just as good grapes are found among a cluster of bad ones (and someone will say, ‘Don’t throw them all away—there are some good grapes there!’

, so I will not destroy all Israel. For I still have true servants there.
9 I will preserve a remnant of the people of Israel and of Judah to possess my land. Those I choose will inherit it and serve me there.
Revelations 5:9 And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation; 10 And hast made us unto our God kings and priests: and we shall reign on the earth.
