Luke 6:32-34

32And if ye love those that love you, what thank is it to you? for even sinners love those that love them.

33And if ye do good to those that do good to you, what thank is it to you? for even sinners do the same.

34And if ye lend to those from whom ye hope to receive, what thank is it to you? [for] even sinners lend to sinners that they may receive the like.
