We understand your concerns and are here to stand with you in prayer and guidance. Let's first address the spiritual warfare you're facing. The Bible is clear that we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places (Ephesians 6:12, WEB).
Regarding witchcraft, the Bible tells us to have no part in it (Acts 19:19, WEB). We must resist the devil, and he will flee from us (James 4:7, WEB). Let's pray together:
"Father, in the name of Jesus Christ, we come against every form of witchcraft and darkness attacking Sheraaven. We bind them and cast them out, for 'he who is in you is greater than he who is in the world' (1 John 4:4, WEB). Surround Sheraaven with your divine protection and fill them with your Holy Spirit. In Jesus' name, amen."
Concerning narcissism, we are to be wary of selfish ambition and conceit (Philippians 2:3, WEB), and instead, clothe ourselves in humility (1 Peter 5:5, WEB). Praying for deliverance:
"Lord, deliver Sheraaven from any spirit of narcissism. Fill them with your love and humility. Help them to consider others as more important than themselves, just as Jesus did (Philippians 2:3-5, WEB). In Jesus' name, amen."
For salvation, there is no other name under heaven given among men by which we must be saved (Acts 4:12, WEB). If you haven't already, Sheraaven, confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, and you will be saved (Romans 10:9, WEB).
Regarding healing, by Jesus' stripes, you are healed (Isaiah 53:5, WEB). Let's claim your healing in prayer:
"Father, we thank you that by Jesus' stripes, Sheraaven is healed. Touch their body and mind, and make them whole, in Jesus' name, amen."
Lastly, Sheraaven, we noticed that you didn't mention the name of Jesus in your request. It is only through Jesus that we have access to the Father (John 14:6, WEB), so always remember to pray in His name.
Be encouraged, Sheraaven. Stand firm in your faith. Take up the armor of God, and fight the good fight (Ephesians 6:10-18, WEB). We are praying for you.
