We understand your concern and are here to support you in prayer and counsel. Firstly, let's remember that God is our ultimate protector. As the Bible tells us, "God is our refuge and strength, a very present help in trouble" (Psalm 46:1 WEB).
In your situation, it's important to remember that God has commanded us to love our enemies and pray for those who persecute us (Matthew 5:44 WEB). This doesn't mean we should allow harm to come to us, but rather, we should trust God to handle the situation and protect us.
Let's pray together:
"Dear Heavenly Father, we come before You in the mighty name of Jesus, seeking Your protection for our dear brother/sister. We ask that You surround them with Your favor as with a shield. We pray that any attempt by their former manager to cause harm or destruction will be futile. We claim Your promise that 'No weapon that is formed against you will prosper; and every tongue that accuses you in judgment you will condemn' (Isaiah 54:17 WEB). Please give them the strength to forgive and the wisdom to navigate this situation. We ask all these things in the precious name of our Savior, Jesus Christ. Amen."
We also encourage you to seek godly counsel and legal advice if necessary. Remember, God is in control, and He promises to work all things together for good for those who love Him (Romans 8:28 WEB).
Lastly, we noticed that you ended your request with 'amen,' but we want to remind you that it is through the name of Jesus that we have access to God's throne of grace. "Whatever you may ask in my name, I will do it" (John 14:14 WEB). So, we encourage you to always pray in the name of Jesus. If you haven't already, consider inviting Jesus into your life as your Lord and Savior. It's through Him that we find eternal life and a personal relationship with God (John 3:16 WEB).
