So I thought it necessary to urge the brothers to go on ahead to you and arrange in advance for the gift you have promised, so that it may be ready as a willing gift, not as an exaction.

The point is this: whoever sows sparingly will also reap sparingly, and whoever sows bountifully will also reap bountifully. Each one must give as he has decided in his heart, not reluctantly or under compulsion, for God loves a cheerful giver. And God is able to make all grace abound to you, so that having all sufficiency in all things at all times, you may abound in every good work.

2 Corinthians 9:5-8
