Luke 6:33-35

33If you do what is good to those who are good to you, what credit is that to you? Even sinners do that.

34And if you lend to those from whom you expect to receive, what credit is that to you? Even sinners lend to sinners to be repaid in full.

35But love your enemies, do what is good, and lend, expecting nothing in return. Then your reward will be great, and you will be children of the Most High. For he is gracious to the ungrateful and evil.
