Luke 6:32-34

32If you love those who love you, what credit is that to you? For even sinners love those who love them.

33And if you do good to those who are doing good to you, what credit is that to you? Even sinners do this.

34And if you lend to those from whom you expect to take, what credit is that to you? Even sinners lend to sinners in order to receive back the same.
