We understand your concern and we are here to support you in prayer and guidance. First, we would like to address that we noticed that the name of Jesus was not mentioned in your request. It is through the name of Jesus that we have access to God, as it is written in John 14:13-14 WEB, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it." Also, in Acts 4:12 WEB, it is written, "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!" So, we encourage you to always approach God in the name of Jesus.
Regarding your request to expose the work of thieves, we must be cautious and wise. It is important to remember that our struggle is not against flesh and blood, but against the spiritual forces of evil in the heavenly places, as stated in Ephesians 6:12 WEB. We should not seek vengeance or to expose others through our own efforts, but rather, we should pray for God's justice and protection.
Let us pray for you:
"Heavenly Father, we come before You in the name of Jesus Christ. We lift up our friend to You, asking for Your divine protection over them, especially in their workplace. Lord, we ask that You expose any works of darkness and bring to light what is hidden. We pray that You frustrate the plans of those who seek to harm or steal, and that You turn their hearts towards repentance. Protect our friend from any harm or retaliation, and surround them with Your favor as with a shield. We ask for Your wisdom and discernment to guide their actions and words. May Your peace, which surpasses all understanding, guard their heart and mind in Christ Jesus. We rebuke any spirit of fear or anxiety, and we declare Your sovereignty over this situation. In Jesus' mighty name, we pray. Amen."
We encourage you to continue to seek God's will in this matter and to trust in His protection. Remember, "The Lord is my light and my salvation. Whom shall I fear? The Lord is the strength of my life. Of whom shall I be afraid?" (Psalm 27:1 WEB). Also, "Don’t be afraid, for I am with you. Don’t be dismayed, for I am your God. I will strengthen you. Yes, I will help you. Yes, I will uphold you with the right hand of my righteousness." (Isaiah 41:10 WEB).
Lastly, we advise you to be cautious and wise in your actions. If you have evidence of wrongdoing, it may be appropriate to report it to the proper authorities, but always do so with a heart of love and a desire for justice, not vengeance. Trust in God's timing and His ways, for they are perfect.
