2 Corinthians 9:7-8 (AMP)

 Let each one give [thoughtfully and with purpose] just as he has decided in his heart, not grudgingly or under compulsion, for God loves a cheerful giver [and delights in the one whose heart is in his gift]. 

8 And God is able to make all grace [every favor and earthly blessing] come in abundance to you, so that you may always [under all circumstances, regardless of the need] have complete sufficiency in everything [being completely self-sufficient in Him], and have an abundance for every good work and act of charity.
