2 Corinthians 8:5-9

They even did more than we had hoped, for their first action was to give themselves to the Lord and to us, just as God wanted them to do. So we have urged Titus, who encouraged your giving in the first place, to return to you and encourage you to finish this ministry of giving. Since you excel in so many ways—in your faith, your gifted speakers, your knowledge, your enthusiasm, and your love from us—I want you to excel also in this gracious act of giving. I am not commanding you to do this. But I am testing how genuine your love is by comparing it with the eagerness of the other churches. You know the generous grace of our Lord Jesus Christ. Though he was rich, yet for your sakes he became poor, so that by his poverty he could make you rich.
