"And masters, treat your slaves in the same way. Do not threaten them, since you know that he who is both their Master and yours is in heaven, and there is no favoritism with him." NIV translation
This discipline (basic training) extends to those who have been blessed by God with the authority over others in the workplace. If you are a supervisor, owner, foreman, etc. then you are to treat those under you (slaves) as you would if Jesus came to work for you. After all, He is the Boss (Master) of all. Brothers and sisters, if you are in a workplace that you hate, then introduce your supervisor to his Master and then show him/her this passage of scripture. Jesus can change anyone and it could become the place where everyone would like to work.
