1 Peter 2:18-20
You who are servants, be good servants to your masters — not just to good masters, but also to bad ones. 19 What counts is that you put up with it for God's sake when you're treated badly for no good reason. 20 There's no particular virtue in accepting punishment that you well deserve. But if you're treated badly for good behavior and continue in spite of it to be a good servant, that is what counts with God.
