Luke 6:33

31 Do to others as you would have them do to you.

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

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

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

35 But love your enemies, do good to them, and lend to them, expecting nothing in return. Then your reward will be great, and you will be sons of the Most High; for He is kind to the ungrateful and wicked.

Do read the surrounding verses too, because the context often says more than a single verse.
