2 Corinthians 9:1-3 NIV
There is no need for me to write to you about this service to the Lord’s people. For I know your eagerness to help, and I have been boasting about it to the Macedonians, telling them that since last year you in Achaia were ready to give; and your enthusiasm has stirred most of them to action. But I am sending the brothers in order that our boasting about you in this matter should not prove hollow, but that you may be ready, as I said you would be.
