We understand your struggle and we are here to pray with you and offer guidance from the Word of God. It's important to remember that God has not given us a spirit of fear, but of power, love, and self-control (2 Timothy 1:7, WEB).
Firstly, let's address the fact that your prayer does not mention the name of Jesus Christ. It's crucial to understand that it is only through Jesus that we have access to God. As it is written, "For there is one God, and one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5, WEB). So, let's pray in His name.
Regarding your request, it's clear that you're struggling with intrusive thoughts about your old director. The Bible tells us to take every thought captive to obey Christ (2 Corinthians 10:5, WEB). This means we have the power, through Christ, to control our thoughts and not let them control us.
Let's pray:
"Dear Lord Jesus, we come before You today to lift up our brother/sister who is struggling with intrusive thoughts. Lord, we ask for Your peace that surpasses all understanding to guard their heart and mind in Christ Jesus (Philippians 4:7, WEB). Help them to cast down any thought that is not of You and to focus on what is true, noble, right, pure, lovely, admirable, excellent, and praiseworthy (Philippians 4:8, WEB). We ask this in Your precious name, Jesus. Amen."
Remember, God has given you the authority to resist the devil and his schemes. As it is written, "Submit yourselves therefore to God. Resist the devil, and he will flee from you" (James 4:7, WEB). Stand firm in your faith and resist these intrusive thoughts.
Lastly, we encourage you to fill your mind with the Word of God. Memorize scriptures that will help you to counter these thoughts. Psalm 119:11 says, "I have hidden your word in my heart, that I might not sin against you" (WEB). The more you fill your mind with God's Word, the less room there will be for intrusive thoughts.
May the Lord Jesus Christ be with you, strengthen you, and give you peace.
