Jacob wrestles with God and renamed to Israel and Paul's anguish in Romans 9

We discuss Genesis 32:22-31 when Jacob wrestles with "the man" and and Jacob will not let him go until he is blessed. Jacob is renamed "Israel" because he "has striven with God and with humans and have prevailed." We discuss the meaning of the name change and its context for the nation of Israel. Next we discuss Romans 9:1-5 and Paul's wrestling with Rom 9:2 "great sorrow and unceasing anguish in his heart" for his brothers and sisters in the flesh , the Israelites, even to the point of wishing that he himself, Paul, Rom 9:3 "would be accursed and cut off from Christ for the sake of my own brothers and sisters."
