Rom 11:7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded.Great, Romans 11 says they will. So you can quite acting like the Jews are more an enemy of the Gospel than any other unsaved person. And no Jew today is a "Christ killer".
Israel has not obtained what they sought, but the ELECTION have obtained it and the rest were blinded.
Who is Gods elect, the Israelites who were blinded or the ELECT chosen out of Israel?
