2 Corinthians 8:4-8

4they begged us earnestly for the privilege of sharing in the ministry to the saints,

5and not just as we had hoped. Instead, they gave themselves first to the Lord and then to us by God’s will.

6So we urged Titus that just as he had begun, so he should also complete among you this act of grace.

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.
