Most look at chapters 9-11 as a shift in Romans, as St. Paul shows that God has not rejected Israel and turned His back on promises He has made. In this chapter, we see St. Paul speak from a place of great love for his Jewish brethren. He wants them to see that they have rejected God and everything He offered them. That is, it is they who have left God and not God who left them. He confirms that they are God’s chosen people, not due to any personal distinction or entitlement they possess; rather, it is due to God’s love. In this sense, God also has proclaimed His love to the Gentiles and He has chosen them as well.
This can be one of the tougher chapters - people often stumble over the language of God choosing people and preferring some people over other people. But it is really all about the free choice that people have and whether we choose God.
