Romans 9:30-33

30What shall we say then? That the Gentiles, who followed not after righteousness, have attained to righteousness, even the righteousness which is by faith. 31But Israel, who followed after the law of righteousness, hath not attained to the law of righteousness. 32Why? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumblingstone; 33As it is written, Behold, I lay in Zion a stumblingstone and rock of offence: and whoever believeth on him shall not be ashamed.1
