In an email exchange this morning, one of my coworkers wrote to me "I'm honestly at a loss here, I don’t even know how to respond to this latest fiasco." This particular coworker and I talk about faith a lot, making it feel natural to replying with what I think ended up being a Spirit-led response. I'm posting that here because I think most of us feel "at a loss" at work from time to time.
You could respond by saying, "my job is stressful, but my job doesn't define me. God defines me. My job is stressful, but I don't need to allow it that power to consume me. My job will not follow me home and stress me out there (I have my family to take care of giving me stress there!). My job is stressful, but I am employed. My job is stressful, but my spouse supports me unconditionally. My job is stressful, but I know I live for something so much more than just my job. My job is stressful, but every day at my job, I have the opportunity to minister to my coworkers, usually in ways they won't be conscious of, but subtle ministry that affects them nonetheless. My job is stressful, but my God is bigger than that stress. My job is stressful, but I am God's child, I am beloved by the Most High King, I am a son/daughter of the Most High King, and that will get me through the day."
