1 Peter 2:18-20

18You who are slaves must obey your masters. Always respect them. Do that to every kind of master. Obey those who are good and kind. But also obey masters who are not fair to you.

19This makes God happy. Maybe your master will punish you when you have done nothing wrong. If you know that you are serving God, continue to be patient and brave.

20But if you do something wrong, then your master ought to punish you. That is only fair. Even if you are brave when he is cruel to you, nobody should praise you for that. But your master may punish you even when you have done good things. Then God will be happy if you are patient and brave.
