They are God's Chosen People; they were called that long before Christ arrived. I kinda agree with Kolo. I don't believe that God has withdrawn His covenant from the Jewish Nation.
It's conditional. Besides, using in part Jeremiah, the author of Hebrews 8:6, 13, Heb 9 suggests otherwise.
God makes many covenants (with Noah, Abraham, with Moses, with David, with Job, Ps 50:5 says God makes covenant with individuals who offer him sacrifice, with the house of Judah and the house of Israel, and then a separate one with the house of Israel, a new government at the Last Supper, etc.) and in Hebrew 8 it declared that Old Covenant was not eternal (although, of course, the Bible contradicts itself on that too).
