2 Corinthians 8:2-5

They are being tested by many troubles, and they are very poor. But they are also filled with abundant joy, which has overflowed in rich generosity. For I can testify that they gave not only what they could afford, but far more. And they did it of their own free will. They begged us again and again for the privilege of sharing in the gift for the believers in Jerusalem. 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.
