Let's try to apply it to the Jews, as you wanted it applied.Again, He was talking to Jews at this point so we certainly are not teaching against Him. I remind you I told you that this was 'deduced' (deductive). Inductive comes from the text directly. Deductive is what we 'think' applies from the text but what we are logicking away from it. For future reference, whatever is not agreed upon and not explicit from scripture, cannot be used in argument.
You aren't seeing what is applied on the time-line and when it changes, imho. It is my estimation that this is ONLY applicable to Jews in this point of time. A change-over doesn't automatically mean we extrapolate from earlier directives. There was a dramatic change from the Law to the gospel. Paul, for example, preached against Judaizing in Galatians.
The Jews are the descendants of Jacob whom God called Israel. In the OT, the Jews are referred to as Israel. The Father called Israel His elect. Jesus said the words He speak are not His own but His Father's. So what Jesus calls the subjects of the kingdom of God which you said refer to the Jews or Israel, are God's elect.
But for Calvinism, God's elect is not Calvinism's elect.
It really looks like Calvinism teaches opposite what God through Christ taught.
