We understand that you are seeking deliverance from evil in your household and protection from someone who has vowed to use you for demonic transactions. Firstly, we commend you for acknowledging the power of the Lord and standing on His word, which says, "You shall not allow a sorceress to live" Exodus 22:18 WEB.
Let us pray together for you:
Dear Heavenly Father, we come before You in the mighty name of Jesus Christ, seeking Your divine intervention and deliverance. We plead the blood of Jesus over this household and claim Your protection and deliverance from the evil scheming to harm Your children. We rebuke the spirit of witchcraft and every demonic transaction assigned against your family. We command this witch to no longer harm your family EXODUS 22:18 WEB. We stand on Your word in Psalm 91, "He who dwells in the secret place of the Most High will rest in the shadow of the Almighty. I will say of Yahweh, 'He is my refuge and my fortress; my God, in whom I trust.'" We ask You, Lord, to fight this battle and receive all the glory, honor, and praise. In Jesus Christ's name, we pray. Amen.
We encourage you to continue standing on the word of God and to remain steadfast in prayer. Remember, "The God of peace will soon crush Satan under your feet. The grace of our Lord Jesus Christ be with you" Romans 16:20 WEB.
You are also a new creature in Jesus Christ. "Therefore if anyone is in Christ, he is a new creature. The old things have passed away. Behold, all things have become new" 2 Corinthians 5:17 WEB. Part of this new creation is a new family. Your faith and trust is to be in God through the name of Jesus Christ, not in the protection of a father or other relative. You are now a member of God's family. If your father is demonic, then you must trust the God and Father of our Lord Jesus Christ as your Father. The blood of Jesus Christ protects you.
Ensure that your household is serving the Lord with all your heart, soul, mind, and strength. Stay in close fellowship with other believers and remain covered in prayer. If there are any items in your household that represent witchcraft or any other form of idolatry, remove them immediately. "You shall have no other gods before me" Exodus 20:3 WEB.
Lastly, be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: 1 Peter 5:8 WEB. God has not given us a spirit of fear. Stay close to Him and allow Him to fight your battle. Be wise but do not fear what man or Satan can do to you. Jesus has already overcome the world. John 16:33 WEB.
