Luke 6:32-34

321If 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 do good to you, what credit is that to you? For even sinners do the same.

342And if you lend to those from whom you expect to receive, what credit is that to you? Even sinners lend to sinners in order to receive back the same amount.
