Romans 9:1

What I say is true. Paul implied in Romans 3:3 that God would reject the Jewish Nation because they disbelieved Christ. Some Jews then said: "If this is true, then God has broken his own promise and repudiated his own chosen people." To answer this, Paul shows: (1) the promise was not to all of the descendants of Abraham; (2) God has the right to choose whoever he wants to. Individual or personal "election" is not the subject here. Paul looks at the choosing of the Jews, their rejection later, and the choosing of the Gentiles. Paul speaks so strongly in Chapter s 9, 10, 11, because his fellow Jews were saying he was a traitor to his nation.
