2 Corinthians 8:6-9

So we urged Titus that as he had previously made a beginning, so he would also complete in you this gracious work as well. But just as you abound in everything, in faith and utterance and knowledge and in all earnestness and in the love we inspired in you, see that you abound in this gracious work also. I am not speaking this as a command, but as proving through the earnestness of others the sincerity of your love also. For you know the grace of our Lord Jesus Christ, that though He was rich, yet for your sake He became poor, so that you through His poverty might become rich.
