1 Peter 2:18-21 (ESV)
18 Servants, be subject to your masters with all respect, not only to the good and gentle but also to the unjust. 19 For this is a gracious thing, when, mindful of God, one endures sorrows while suffering unjustly. 20 For what credit is it if, when you sin and are beaten for it, you endure? But if when you do good and suffer for it you endure, this is a gracious thing in the sight of God. 21 For to this you have been called, because Christ also suffered for you, leaving you an example, so that you might follow in his steps.
