"Whatever your task, put yourselves into it, as done for the Lord and not for your masters, since you know that from the Lord you will receive the inheritance as your reward; you serve the Lord Christ." Colossians 3:23-24 (NRSV)
Have you ever worked at a job you really disliked? It's been years, but I know I have and currently know a few people in this situation. It’s often not the job itself, but the person you are working for is the challenge. Facing constant unrealistic demands by difficult people sometimes make going to work very hard and unpleasant. Sadly this is the way of the world. Fortunately, we work for many good people, but occasionally we end up with one other kind.
We can't change those folks--only God can do that--but we can control how we respond. We can change our mindset from working for a problematic earthly person to serving someone much higher. When we do what we do for God, we achieve a totally different perspective. We may still need to meet the ridiculous demands of man, but God is the one in charge. By devoting our work to God internally, our outward demeanor also changes. Who knows, perhaps this will serve as a witness to the person creating the difficulties, but guaranteed are the wonders it will do for us spiritually, mentally, and physically. As for that problematic person--keep on praying for them.
God, we give thanks for employment. We are intended to work and be fruitful. We dedicate our tasks to you. Please help us as we encounter challenges in our jobs to respond according to your will. May others witness the light of Jesus through us. Amen.
While many reading this may be retired, dealing with difficult folks isn't limited to the pre-retired. We all employ our time and talents in some way and have equal opportunities to encounter difficult folks. In all things, we should put Christ first.
