2 Corinthians 9:5-7

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. Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously. Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
