Ephesians 6:9  “Masters, it’s the same with you. No abuse, please, and no threats. You and your servants are both under the same Master in heaven. He makes no distinction between you and them.” 

We all know that aphorism by Lord Acton:  Power corrupts and absolute power corrupts absolutely.  Basically, people will get away with as much as they can.  A remarkable exception is George Washington.   He was given repeated opportunity to consolidate power in himself.   There was talk of making him king, and of referring to him as “your Excellency.”  He eschewed it all, declined to run again for office, and retired to Mt. Vernon.  
By contrast, we often see little tyrants in the workplace.  They do not lead by example or inspiration, but by threat and intimidation.  They do not build other people up, but tear them down.  They insult, badger, criticize, and become stern and cold in their relations.  How do they get away with it?  Because they are “the boss.”  Why do they get away with it?  Because they can.  If you work in such an environment, it likely is making you emotionally and physically sick.  
Verse 9 states a different model for Christian relations in the workplace.  No workplace bullies are allowed in this model.  Jesus is your CEO.  No wielding of titles or positions in this company.  Jesus came to love, to serve, to redeem.  Jesus wants to bring out our best.  He works that we might be our best.  His spirit is one of freedom married to responsibility:  a perfect balance of grace and truth.  The result is superlative work by joy-filled employees.  The work may not be easy or even very stimulating, but it is done with an attitude of service to the King.  Non-believers take notice, and the Kingdom is advanced by example, not only by word.
