“Slaves, in reverent fear of God submit yourselves to your masters, not only to those who are good and considerate, but also to those who are harsh. 19 For it is commendable if someone bears up under the pain of unjust suffering because they are conscious of God. 20 But how is it to your credit if you receive a beating for doing wrong and endure it? But if you suffer for doing good and you endure it, this is commendable before God.”
God is glorified when Christians patiently endure justice and do not lash back and take revenge on those who hurt them. We as Christians need to remember to always behave appropriately towards authority, even when they obey inappropriately towards us. We must still obey our bosses, for instance, even if they are mean to us. We must still treat our parents with respect even if they are cruel to us. We must still treat our government with respect even if it is unjust to us.
There are many people in this world who suffer justly for their own sins and selfishly complain about it. But we, as true Christians, need to set an example by not lashing out when we suffer unjustly.
