Here Come The Judge
When you came to Christ, you entered into a personal relationship with Him. He allows you to know what He wants through the Holy Spirit. He has given you understanding of His Word through the Holy Bible. What you need to additionally know is God is dealing with you on a personal level and at the very level YOU need. How He deals with your employees, on their personal level, is not something you should feel compelled to talk about with them.
To talk to an employee about their sin (in your eyes) is not only prohibited by law, it is taking away one of the jobs God has designated as His own. St. Matthew 7:1-3 - "Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?"
It is your job, as a supervisor, to handle dishonesty and other breaks in the company rules and procedures. It may be your job to punish those lapses. It is not your job to mete out judgment or punishment, in any form, for an employee's personal sin.
What if they come to you about a personal problem that involves sin? In the forty years of working, I have never had an employee ask me to judge their sins. I've had them want to talk about issues or problems but never did they ask for judgment. I've had them ask for advice but never judgment.
Where am I going on this judgment thing? It is when you judge an employee based upon what you perceive as sin. It can encompass an employee's race, religion, , economic status, position in the company, sexual, gender, and others. And although you may feel you are rightly judging another based upon your Christian beliefs, read Matthew again.
As a Christian supervisor, it is your job to witness through fair treatment of all. You may offer personal prayers for the soul of others because you believe they are sinning. You may not discriminate, chastise, mention, rate, or tell others. Trust God to work in their hearts. Trust God to use your witness of integrity and fairness in the workplace. Trust God to make the judgment more accurate and compassionate than any human supervisor. Trust that God will have a personal relationship devoted to their soul. And as Matthew continues, 7:4-5 - "Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye. Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brothers eye. "
The very act of judging others (which belongs to God) is sin. When we step up to take the Lord's work from Him and feel we can and should judge others - we are committing a sin and God directs us to take away our own sin before evening thinking about others. A job that will keep most of us quite busy. Aren't we all relieved to know that the Lord our God will judge us with His infinite knowledge of our hearts and we won't be judged by another imperfect mortal.
