2 Corinthians 8:5-9

Not only [did they give materially] as we had hoped, but first they gave themselves to the Lord and to us [as His representatives] by the will of God [disregarding their personal interests and giving as much as they possibly could]. So we urged Titus that, as he began it, he should also complete this gracious work among you as well. But just as you excel in everything, [and lead the way] in faith, in speech, in knowledge, in genuine concern, and in your love for us, see that you excel in this gracious work [of giving] also. I am not saying this as a command [to dictate to you], but to prove, by [pointing out] the enthusiasm of others, the sincerity of your love as well. For you are recognizing [more clearly] the grace of our Lord Jesus Christ [His astonishing kindness, His generosity, His gracious favor], that though He was rich, yet for your sake He became poor, so that by His poverty you might become rich (abundantly blessed).
