God's Sovereign Choice
Why not? Because their pursuit was not by faith, but as if it were by works. They stumbled over the stumbling stone, Romans 9:32 · Berean Standard Bible
Why didn't Israel attain righteousness? Because they pursued it as if it were about their own works—their effort and obedience—rather than trusting in what God would do. They stumbled over Jesus, the stumbling stone.
Paul identifies the core problem: Israel approached righteousness as an achievement rather than a gift. They built their religious identity on performance, so when Jesus came offering righteousness as a gift received through faith, it conflicted with everything they'd been taught. Many rejected Him because He didn't fit their framework.
Paul
Jesus is presented throughout the New Testament as the stone the builders rejected. Israel's rejection of Jesus wasn't accidental—it was the predictable collision between a works-based system and a faith-based gospel.
Israel stumbled because they pursued righteousness through works of the Law rather than through faith, treating the Law as a system to be mastered instead of a pointer to grace.
Paul diagnoses the root cause: 'not by faith, but as if by works' (οὐκ ἐκ πίστεως ἀλλὰ ὡς ἐξ ἔργων, ouk ek pisteos alla hos ex ergon). This is the crystallization of Paul's theological argument throughout Romans: salvation is not the outcome of competitive achievement through legal compliance. The phrase 'stumbled over the stumbling stone' (προσέκοψαν τῷ λίθῳ τοῦ προσκόμματος, prosekopsan to litho tou proskammatos) introduces the metaphor that will dominate verses 33: the stone is Christ Himself. In Isaiah 8:14-15, the stone (צוּר, tsur in Hebrew) represents God's judgment; Paul applies it to Jesus as both the revelation of God's righteousness and the judgment upon those who reject it.
Paul, explicating why Israel 'failed to obtain' righteousness
The whole narrative arc of Israel—from covenant at Sinai to the present—came to a breaking point when the Law itself became an obstacle to recognizing God's righteousness in Christ. The stone over which they stumbled was the revelation of God's mercy itself.
30What then will we say? That the Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith;
31but Israel, who pursued a law of righteousness, has not attained it.
32Why not? Because their pursuit was not by faith, but as if it were by works. They stumbled over the stumbling stone,
33as it is written: “See, I lay in Zion a stone of stumbling and a rock of offense; and the one who believes in Him will never be put to shame.”
Read all of Romans 9 — Paul wrestles with the hardest question: why has Israel rejected its own Messiah? The answer involves a potter, clay, and a sovereignty that bends to no one.
