'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;

while the descendants of Israel, who were in pursuit of a Law that could give righteousness, have not arrived at one.

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.
