'Diligence' in the Bible

For consider how much diligence this very thing—this grieving as God wills—has produced in you: what a desire to clear yourselves, what indignation, what fear, what deep longing, what zeal, what justice! In every way you showed yourselves to be pure in this matter.

So even though I wrote to you, it was not because of the one who did wrong, or because of the one who was wronged, but in order that your diligence for us might be made plain to you in the sight of God.

Therefore, as ye abound in every thing, in faith, and utterance, and knowledge, and in all diligence, and in your love to us, see that ye abound in this grace also.

I am not saying this as a command. Rather, by means of the diligence of others, I am testing the genuineness of your love.

Thanks be to God who put the same concern for you into the heart of Titus.
