We are truly concerned for the soul of your friend's girlfriend who has become entangled with demonic powers. We stand with you in prayer, seeking God’s deliverance and salvation for her. It is crucial to remember that our battle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms (Ephesians 6:12, WEB).
Firstly, we must address that prayer in the name of Jesus Christ is the only way to approach God the Father. It is only through Jesus that we have access to God, and it is only through His name that we can be saved. 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) and "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!" (Acts 4:12, WEB).
We rebuke the spirits that have taken hold of her and pray for her release from their grip. Let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up the girlfriend of our friend to You. Lord, we know that You desire for all to come to repentance and knowledge of the Truth. We pray that You would deliver her from the evil one and bring her into the light of Your Son, Jesus Christ.
We rebuke the demonic powers that have taken hold of her life, and we command them to flee in the name of Jesus. Lord, we ask that You would open her eyes to see the darkness she is involved in and the light of the Gospel. Grant her the courage to turn away from her sin and to turn to You.
Surround her with Godly influences, and bring believers into her life who will share the Gospel with her and disciple her in her walk with You. Lord, we ask that You would transform her life and use her testimony for Your glory.
We also pray for her boyfriend/fiancé/potential husband. We pray for his strength as he should be the spiritual leader. We pray that he would be submitting to God and God's will in his life and relationship with his girlfriend. We pray for a strong Christian marriage between him and his girlfriend, and we pray that any sexual immorality between them would be addressed and taken care of through Christ.
We ask this in the powerful name of Jesus Christ, who lives and reigns with You and the Holy Spirit, one God, forever and ever. Amen.
Continue to pray fervently for her, and trust that God is at work in her life. Remember, "The effective, fervent prayer of a righteous man avails much" (James 5:16, WEB).
We also encourage you to share the Gospel with her and with their boyfriend/fiancé/potential husband, as it is written, "How then will they call on him in whom they have not believed? How will they believe in him whom they have not heard? How will they hear without a preacher?" (Romans 10:14, WEB). Be bold in your witness, and trust that God will use your words to draw her to Himself and to draw her boyfriend to Himself and His will.
