2 Corinthians 8:7-9

7Now as you excel in everything — in faith, speech, knowledge, and in all diligence, and in your love for us  — excel also in this act of grace.

8I am not saying this as a command. Rather, by means of the diligence of others, I am testing the genuineness of your love.

9For you know the grace of our Lord Jesus Christ: Though he was rich, for your sake he became poor, so that by his poverty you might become rich.
