2 Corinthians 8:1-6

Now, brethren, we wish to make known to you the grace of God which has been given in the churches of Macedonia, that in a great ordeal of affliction their abundance of joy and their deep poverty overflowed in the wealth of their liberality. For I testify that according to their ability, and beyond their ability, they gave of their own accord, begging us with much urging for the favor of participation in the support of the saints, and this, not as we had expected, but they first gave themselves to the Lord and to us by the will of God. So we urged Titus that as he had previously made a beginning, so he would also complete in you this gracious work as well.
