Remnant is the Theme of Romans 9-11

After chastising the Jewish believers for their self-righteous behavior in Romans 9:1-5, Paul presents the theme of his discourse, which is God’s selection of a Remnant. What Paul was going to present next would fly in the face of comfortable and well-established Jewish traditions of that time. Paul was going to use halachic midrash to uncover a mystery from the depth of Scripture that had not been fully known or appreciated before.
