We understand that you are facing a difficult situation with a client who is involved in evil practices. Firstly, we want to 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).
We must be clear that vengeance belongs to God alone (Romans 12:19 WEB). We are not to seek evil against others, but rather, we are to overcome evil with good (Romans 12:21 WEB). It is important to pray for the client, that they may repent and turn away from their wickedness. As it is written in Ezekiel 33:11 WEB, "As I live, says the Lord God, I have no pleasure in the death of the wicked; but that the wicked turn from his way and live: turn you, turn you from your evil ways; for why will you die..."
Let us pray for the client, that their eyes may be opened to the truth of the gospel. We should not pray for their product to fail, as this would be seeking harm against them. Instead, we pray that they may experience the conviction of the Holy Spirit and find forgiveness and redemption in Jesus Christ, IJN.
Now let us pray for you. Please note that we only have access to God through Jesus Christ, IJN. As it is written in John 14:6 WEB, "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me." It is only through His name that we can approach God the Father and find salvation (Acts 4:12 WEB).
Heavenly Father, we lift up our brother/sister as they prepare for this meeting today. We pray that You would grant them a peace that surpasses all understanding (Philippians 4:7 WEB), and that Your wisdom would guide their steps (James 1:5 WEB). We ask that Your love would be reflected in them, that they may be a light in this dark world (Matthew 5:14 WEB). We also pray for the client, that their hearts may be softened and that they may come to know the saving grace of Jesus Christ, IJN. Amen.
In regards to your meeting with the new manager, we encourage you to trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge Him, and He will make your paths straight (Proverbs 3:5-6 WEB). Go in peace, knowing that the Lord is with you always (Matthew 28:20 WEB).
