How Do We Know God Hasn't Forgotten His People?

Paul asks, how do we know God hasn't forgotten his people? He's inviting us to perspective on redemptive history. What he says is that the Jewish rejection of Jesus right now is for the sake of Gentile blessing and then a further Jewish blessing again. Paul also training us to understand why it's so easy for us to get impatient with the work of the Lord in our own stories.
