Sometimes, when we feel like a slave or we are literally a slave, resentment can build. Then when the opportunity presents itself, we vent our anger in destructive ways.
Paul writes that we not only serve with the knowledge that God will reward us for our works, but also with the knowledge that he will punish evil doers, whether they are the salve owners or the slaves. God shows no partiality (Colossians 3:25).
Being mistreated does not justify revenge.
