'Earnest' in the Bible

For behold, this same thing, that you were made sorry in a godly way, what earnest care it worked in you. Yes, what defense, indignation, fear, longing, zeal, and vengeance! In everything you demonstrated yourselves to be pure in the matter.

So although I wrote to you, I wrote not for his cause that did the wrong, nor for his cause that suffered the wrong, but that your earnest care for us might be revealed in you in the sight of God.

But thanks be to God, who puts the same earnest care for you into the heart of Titus.

For he indeed accepted our exhortation, but being himself very earnest, he went out to you of his own accord.

We have sent with them our brother, whom we have many times proved earnest in many things, but now much more earnest, by reason of the great confidence which he has in you.
