2 Corinthians 8:4-8

4Praying us with much intreaty that we would receive the gift, and take upon us the fellowship of the ministering to the saints. 5And this they did, not as we hoped, but first gave their own selves to the Lord, and unto us by the will of God.

6Insomuch that we desired Titus, that as he had begun, so he would also finish in you the same grace also. 7Therefore, as ye abound in every thing, in faith, and utterance, and knowledge, and in all diligence, and in your love to us, see that ye abound in this grace also. 8I speak not by commandment, but by occasion of the forwardness of others, and to prove the sincerity of your love.
