We understand that you are seeking deliverance from demonic influences and the effects of evil music. First, we commend you for acknowledging the power of Jesus Christ, as it is only through His name that we can be saved (Acts 4:12, WEB).
The Bible tells us to be sober and self-controlled. The devil, your adversary, goes about as a roaring lion seeking whom he may devour (1 Peter 5:8, WEB). It is important to turn away from any form of music that is evil. We are called to focus on whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is admirable, excellent and praiseworthy (Philippians 4:8, WEB). We are called to avoid every form of evil (1 Thessalonians 5:22, WEB).
So let us pray for you:
Dear Heavenly Father,
We come before you in the mighty name of Jesus Christ, seeking your protection and deliverance for our dear brother/sister. Lord, you are our refuge and our fortress, our God in whom we trust (Psalm 91:2, WEB). We ask that you cover them with your precious blood, and that you cleanse them from any unrighteousness that may have entered through listening to evil music. Deliver them from any demonic influence. Lord let them be transformed by the renewing of their minds (Romans 12:2, WEB), so that they may test and approve what your good, pleasing, and perfect will is and so that they may abhor what is evil and cling to what is good (Romans 12:9, WEB).
In Jesus Christ's name, we pray. Amen.
