Paul begins by stating that he has great sorrow and anguish in his heart. He says that he wished that he would be cut of from Jesus if it meant that they other Jews would be saved. He then proceeds to explain that God’s children aren’t just the descendants of Abraham, as many of the Jews believed. It is, instead, that the people who follow God who are his children. Paul then explains that God’s judgement is based on his will, not human desire or effort. He explains that God has mercy upon whomever He wants to have mercy. Paul quotes Isaiah saying, “‘Though the number of the Israelites be like the sand by the sea, only the remnant will be saved. For the Lord will carry out his sentence on earth with speed and finality.’” The next and final section is very important and I think it's better if it's just quoted instead of summarized. That part of Romans 9 says, “What then shall we say? That the Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith; but the people of Israel, who pursued the law as the way of righteousness, have not attained their goal. Why not? Because they pursued it not by faith but as if it were by works. They stumbled over the stumbling stone. As it is written: ‘See, I lay in Zion a stone that causes people to stumble and a rock that makes them fall, and the one who believes in him will never be put to shame.’” This part shows what Paul was trying to get across to the Israelites. He was trying to tell that that they’d been following God wrong. They had spent so much time trying to interpret the Bible that they basically changed it to just laws. Paul was trying to tell them that following just those laws isn’t going to get them anywhere, even though that's what they thought would make them holy.
