We see Paul's heart in these three chapters of Romans, and his heart is with his people, the Jews. If he could give up his own salvation so that the Jews would come to faith, he would. Paul used a lot of Old Testament Scripture passages in these chapters to show how God chose the Jews, and how He picked Abraham, Isaac, and Jacob. 9:16, "It does not, therefore, depend on man's desire or effort, but on God's mercy." The sovereignty of God is discussed. Please notice that verses 22 & 23 start, "What if," not that "God does." The Lord allowed a hardening of the Jews, so that God would open the way for the Gentiles to enter the family of God. The Jews had not attained this gift of salvation because "they pursued it not by faith, but as if it were by works. They stumbled over the 'stumbling stone'" (9:32). That stumbling stone was Jesus. Some key verses are 10:9-10, "That if you confess with your mouth, 'Jesus is Lord,' and believe in your heart that God raised Him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved." Paul continued by asking, "How can people believe if they have not heard?" Then he declared that the Jews had heard, but because of their hard heart they did not believe. His final explanation was an olive tree with branches that have broken off and died. They represent the Jews, but God then graphed in the Gentile believers, the wild olive shoot." This benefitted both the tree and the wild olive shoot together they make up "All Israel." This section ends with a bursting forth of praise from Paul, about how God is so beyond us, and everything we have and are come from Him, and belongs to Him, including all glory and praise, forever. Amen!
