'Pursue Righteousness' in the Bible

What shall we say, then? That Gentiles who did not pursue righteousness have attained it, that is, righteousness through faith;

But you, man of God, flee from all this, and pursue righteousness, godliness, faith, love, endurance and gentleness.

Now flee from youthful lusts, and pursue righteousness, faith, love and peace, along with those who call on the Lord from a pure heart.
