2 Corinthians 9:5-7 NIV

[5] 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. [6] Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously. [7] 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.
