2 Corinthians 9:4-7

4For if any of the Macedonians should come with me and find that you are not ready to give, we would be humiliated (not to mention you) by this confidence we had in you.

5Therefore I thought it necessary to urge these brothers to go to you in advance and to arrange ahead of time the generous contribution you had promised, so this may be ready as a generous gift and not as something you feel forced to do.

6My point is this: The person who sows sparingly will also reap sparingly, and the person who sows generously will also reap generously.

7Each one of you should give just as he has decided in his heart, not reluctantly or under compulsion, because God loves a cheerful giver.
