30 How can we sum this up? All those people who didn't seem interested in what God was doing actually embraced what God was doing as he straightened out their lives. 31 And Israel, who seemed so interested in reading and talking about what God was doing, missed it. 32 How could they miss it? Because instead of trusting God, they took over. They were absorbed in what they themselves were doing. They were so absorbed in their "God projects" that they didn't notice God right in front of them, like a huge rock in the middle of the road. And so they stumbled into him and went sprawling. 33 Isaiah (again!) gives us the metaphor for pulling this together: Careful! I've put a huge stone on the road to Mount Zion, a stone you can't get around. But the stone is me! If you're looking for me, you'll find me on the way, not in the way.

Commentary on Romans 9:30-33
(Read Romans 9:30-33)
The Gentiles knew not their guilt and misery, therefore were not careful to procure a remedy. Yet they attained to righteousness by faith. Not by becoming proselytes to the Jewish religion, and submitting to the ceremonial law; but by embracing Christ, and believing in him, and submitting to the gospel. The Jews talked much of justification and holiness, and seemed very ambitious to be the favourites of God. They sought, but not in the right way, not in the humbling way, not in the appointed way. Not by faith, not by embracing Christ, depending upon Christ, and submitting to the gospel. They expected justification by observing the precepts and ceremonies of the law of Moses. The unbelieving Jews had a fair offer of righteousness, life, and salvation, made them upon gospel terms, which they did not like, and would not accept. Have we sought to know how we may be justified before God, seeking that blessing in the way here pointed out, by faith in Christ, as the Lord our Righteousness? Then we shall not be ashamed in that awful day, when all refuges of lies shall be swept away, and the Divine wrath shall overflow every hiding-place but that which God hath prepared in his own Son.
