What shall we say then? That the Gentiles, which followed not after righteousness, have attained to righteousness, even the righteousness which is of faith. But Israel, which followed after the law of righteousness, hath not attained to the law of righteousness. Wherefore? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumblingstone; As it is written, Behold, I lay in Sion a stumblingstone and rock of offence: and whosoever believeth on him shall not be ashamed. ~ Romans 9:30-33 KJV

What then shall we say? That the Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith; but Israel, who pursued a law of righteousness, has not attained it. 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 men to stumble and a rock that makes them fall, and the one who trusts in him will never be put to shame.” ~ Romans 9:30-33 NIV (1984)

What shall we say then? That Gentiles who did not follow after righteousness [who did not seek salvation by right relationship to God] have attained it by faith [a righteousness imputed by God, based on and produced by faith], Whereas Israel, though ever in pursuit of a law [for the securing] of righteousness (right standing with God), actually did not succeed in fulfilling the Law. For what reason? Because [they pursued it] not through faith, relying [instead] on the merit of their works [they did not depend on faith but on what they could do]. They have stumbled over the Stumbling Stone. As it is written, Behold I am laying in Zion a Stone that will make men stumble, a Rock that will make them fall; but he who believes in Him [who adheres to, trusts in, and relies on Him] shall not be put to shame nor be disappointed in his expectations.  ~ Romans 9:30-33 AMP
