'Pursuit' in the Bible

To what conclusion does this bring us? Why, that the Gentiles, who were not in pursuit of righteousness, have overtaken it--a righteousness, however, which arises from faith;

whereas Israel, [though always] pursuing the law of righteousness, did not succeed in fulfilling the law.

How then does the matter stand? It stands thus. That which Israel are in earnest pursuit of, they have not obtained; but God's chosen servants have obtained it, and the rest have become hardened.
