I'll get you started.
In chapters 5-8, Paul is speaking to the subject of assurance. He begins Chapter 5 showing how this is true through the work and person of the Father. As he works through the chapter, he moves from the Father to Christ and how this is made manifest in His words and works.
In chapters 6 and 7, Paul anticipates questions that arise as a result of what he has shared. Chapter 6 deals with grace and license, and chapter 7 deals with the purpose of the law.
In chapter 8, the Apostle again picks up the theme of assurance as mediated through the Holy Spirit, and ends with a resounding crescendo of the love of God for His people.
In chapters 9-11, Paul anticipates questions concerning the Jewish people. Where do they fit into the new covenant, especially since all Jews are not being saved? So Paul addresses the issue. All Jews were never all saved, but only a remnant. All of Israel is not the Israel of God. Only those who were actually saved were ever truly the people of God.
So far from being excluded in the new covenant, they actually exemplify the new covenant and have all along. Just as the Gentiles started small and are growing, so too will the Jews begin small and will grow as a part of the church. And there will come a time when all the Gentiles will come into the kingdom, so there will be a time when the Jews in large number will be represented in the church. But all this is done without a partition between Jew and Greek, but only the new man in Christ exists.
