2 Corinthians 9:1-5 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.  For if any Macedonians come with me and find you unprepared, we---not to say anything about you---would be ashamed of having been so confident.  So I thought it necessary to urge the brothers to visit you in advance and finish the arrangements for the generous gift you had promised. Then it will be ready as a generous gift, not as one grudgingly given.
By describing how their own "enthusiasm" had incited the Macedonians to give, Paul was, in effect, prodding the Corinthians to rekindle their initial enthusiasm for giving. Paul wasn't naive about human behavior. The start and end of a marathon are much more thrilling than the miles in between. It takes stubborn determination to keep going. Paul also knew that it took a community to persevere. Just as teammates will cheer their runner on in a race, so Paul was sending Titus and two other believers to the Corinthians to cheer them on.
