2 Corinthians 9:7

⁷ Each man should give as he has decided in his heart. He should not give, wishing he could keep it. Or he should not give if he feels he has to give. God loves a man who gives because he wants to give. 
⁷ Cada uno debe dar según se lo haya propuesto en su corazón, y no debe dar con tristeza, ni por necesidad, porque Dios ama a quien da con alegría.
