2 Corinthians 9:6-7

New International Version (NIV)

6 Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously.
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.

New King James (NKJ)

6 But this I say: He who sows sparingly will also reap sparingly, and he who sows bountifully will also reap bountifully.
7 So let each one give as he purposes in his heart, not grudgingly or of necessity; for God loves a cheerful giver.

King James Version (KJV)

6 But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully.
7 Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
