2 Corinthians 8:3-8

3For I testify that they gave as much as they were able, and even beyond their ability. Entirely on their own, 4they urgently pleaded with us for the privilege of sharing in this service to the Lord’s people. 5And they exceeded our expectations: They gave themselves first of all to the Lord, and then by the will of God also to us. 6So we urged Titus, just as he had earlier made a beginning, to bring also to completion this act of grace on your part.

7But since you excel in everything—in faith, in speech, in knowledge, in complete earnestness and in the love we have kindled in you Some manuscripts and in your love for us —see that you also excel in this grace of giving. 8I am not commanding you, but I want to test the sincerity of your love by comparing it with the earnestness of others.
