II Corinthians 8:5-7

And not only as we had hoped, but they first gave themselves to the Lord, and then to us by the will of God. So we urged Titus, that as he had begun, so he would also complete this grace in you as well. But as you abound in everything—in faith, in speech, in knowledge, in all diligence, and in your love for us—see that you abound in this grace also.
