We are truly sorry to hear that you are facing such trials at your workplace. Let us remind you that our battle is not against flesh and blood, but against the principalities, against the powers, against the world's rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places (Ephesians 6:12 WEB).
Firstly, we must ensure that you have called upon the name of the Lord Jesus Christ, for Scripture tells us that "in no other is there salvation, for neither is there any other name under heaven, that is given among men, by which we must be saved!" (Acts 4:12 WEB). It is only through the name of Jesus that we have access to God the Father and can claim His protection.
We must also stand against such evil by putting on the whole armor of God.
Stand therefore, having the utility belt of truth buckled around your waist, and having put on the breastplate of righteousness, and having fitted your feet with the preparation of the Good News of peace, above all, taking up the shield of faith, with which you will be able to quench all the fiery darts of the evil one. And take the helmet of salvation, and the sword of the Spirit, which is the word of God; with all prayer and requests, praying at all times in the Spirit, and being watchful to this end in all perseverance and requests for all the saints (Ephesians 6:14-18 WEB).
Let us pray together:
Dear Heavenly Father,
We come before You in the mighty name of Jesus Christ, lifting up our brother/sister who is facing affliction from the enemy through witchcraft attacks from colleagues at the workplace. We stand in the gap for them, claiming Your divine protection and deliverance from this evil.
Father, we put on the whole armor of God, standing firm against the schemes of the devil. We ask that You surround our brother/sister with Your angels, protecting them from all harm and danger. Expose and bind the evil one and their works, and let every curse and spell be broken and returned to the senders sevenfold.
Lord Jesus, You are our victory, and through You, we are more than conquerors. Grant our brother/sister wisdom, discernment, and strength to stand against this evil, and guide them in all truth and righteousness.
Holy Spirit, fill our brother/sister anew, empowering them to resist the devil and his demons, causing them to flee.
Father, we ask for a hedge of protection around our brother/sister's family, home, and belongings. Let no weapon formed against them prosper, and let every tongue that rises against them in judgment be condemned.
In the mighty name of Jesus Christ, we pray. Amen.
Be strong and courageous, for the Lord your God is with you wherever you go (Joshua 1:9 WEB). Do not be afraid or discouraged, for the Lord will personally go ahead of you. He will be with you; he will neither fail you nor abandon you (Deuteronomy 31:8 WEB).
