benefitting from disobedience

Romans 11:25-32

Paul connects disobedience and mercy in this passage. He quotes from Isaiah and Jeremiah to support his point that all Israel will be saved. His main argument is that the hardening of Israel is not a complete and total hardening but that one day they will return to God. I, as a Gentile, benefit from Israel's disobedience. His logic is: Israel disobeyed God so God turned his attention to the Gentiles; this pouring out of mercy on the Gentiles will stir up envy in the heart of Israel and they will repent and receive God's mercy. Because God is in control, it means that he turned us all (Jew and Gentile) over to the disobedience so he could have mercy on is. Our sinfulness was predetermined by God in order to bring him glory.
This does not excuse me (Paul makes that clear - at some level it was still my choice to be disobedient). It does speak of the incredible sovereignty of God and how far he will go to bring himself glory. In a human this would be incredeibly selfish but because there is no one higher than God that he should be seeking glory for, it is right and good (and hard to understand).
