"Let each one give as he has purposed in his heart, not unwillingly or out of compulsion, for 'God loves a cheerful giver' (Prov 22:8). 
But God has the might to bless you abundantly with every gift of grace, so that you may always be sufficient in every way and possess abundant resources for good works of every kind"

(2 Corinthians 9:7-8)
