2 Corinthians 9
v.2-4
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. 3But 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. 4For 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.
v.6
Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously.
v.7
Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
