2 Corinthians 9:7; 2 Corinthians 11:11; 2 Corinthians 12:15

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.
11 Wherefore? because I love you not? God knoweth .
15 And I will very gladly spend and be spent for you ; though the more abundantly I love you, the less I be loved .
