Israel Has Stumbled And Hurt Itself Because It Has Not Believed In Its Messiah And Submitted To The Righteousness Of God Obtainable Through Faith In Him (9:30-33).
Paul emphasises that the believing Gentiles, by responding to the Messiah, have attained to the righteousness which is of faith, the righteousness which was God's gift to them through Christ (Romans 3:24-28; Romans 5:15-19). They had discovered that ‘he who believes on Him will not be put to shame' (Romans 9:33), that is, will have nothing to be ashamed of in the eyes of God the Judge when he comes before Him for judgment. In contrast unbelieving ‘Israel', by rejecting their Messiah, and seeking righteousness by works, have stumbled and fallen on the Messianic stumblingstone (Romans 9:32).
