I Peter 2:18-20

Servants, be submissive to your masters with all fear, not only to the good and gentle, but also to the harsh. For this is commendable, if because of conscience toward God one endures grief, suffering wrongfully. For what credit is it if, when you are beaten for your faults, you take it patiently? But when you do good and suffer, if you take it patiently, this is commendable before God.
