What about the Jewish people who rejected the Messiah? Did God "harden" their hearts? Why did they stumble over Yeshua, and what were the implications? Did the Messianic promises fail? Romans 9 is a pivotal passage for understanding Paul's theology regarding Messiah and Israel. This teaching takes the most difficult chapter of the Epistle to the Romans head on from a Messianic Jewish perspective.
So then he has mercy on whomever he wils, and he hardens whomever he wills. (Romans 9:18)
