I’m sorry to hear about the trouble you are facing at your work place with this person. No detail of our lives can ever escape God’s notice, and I believe He is pleased when we bring even the smallest of our needs to Him in prayer. In fact, He instructs us to do so: “In everything by prayer and supplication with thanksgiving let your requests be made known to God” (Philippians 4:6). I’m praying for you, asking for God’s intervention, help and guidance in this matter a special way.
Psalm 46:1 God is our refuge and strength, a very present help in trouble.
