1 Peter 2:18-21

Slaves, yield to the authority of your masters with all respect, not only those who are good and kind, but also those who are dishonest. A person might have to suffer even when it is unfair, but if he thinks of God and can stand the pain, God is pleased. If you are beaten for doing wrong, there is no reason to praise you for being patient in your punishment. But if you suffer for doing good, and you are patient, then God is pleased. This is what you were called to do, because Christ suffered for you and gave you an example to follow. So you should do as he did.
