Philippians 4:6-7
"Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all comprehension, will guard your hearts and your minds in Christ Jesus."
Lord help this person trust in you with all that concerns them even when at work. Give them your peace and strength and heal them from all anxieties. May they be able to witness to others with the calm you give them and your light shine to others through them. May they always have a kind word and a smile in their face so that others be interested how they can be so at ease. This can be the time for this person to tell them that it's only through your love and the power of our Lord Jesus Christ, and that they too can find that peace through you our
Lord and Savior. I pray in the mighty and healing name of Jesus Christ, Amen.
