We come in the name and authority of Jesus Christ to deal with curses pronounced over the life of X (your full name).
We ask the protection of the blood of Jesus Christ as we pray and we bind the activity of any evil spirits in Jesus name. We claim the full armor of God (read Ephesians 6:10-18).
We confess the sins of the parents and ancestors of X that may have given ground for a curse to alight upon him/her. (Name & renounce the sins esp. idolatry , witchcraft and murder)
We confess any sins in the life of X that may have given ground for a curse to alight upon him/her. (Name & renounce the sins esp. idolatry , witchcraft, sexual immorality and murder)
We claim the forgiveness and cleansing of the blood of Jesus Christ and now assert that no ground remains for a curse to affect the life of X. We assert that X has been seated in the heavenly realms with Christ Jesus far beyond the reach of curses. (Ephesians 1:20, 2:6)
We renounce the curse and all its effects. We break the curse and all its power in the name of Jesus Christ of Nazareth. We plead the blood of the cross on behalf of X and say that Christ has taken all his/her curses on the cross according to Galatians 3:10-14. In accordance with the Scriptures and the will of God we pull down and destroy any strongholds in X's life (2 Corinthians 10:4,5) and we destroy the works of the Devil (1 John 3:8)and turn back the curses and all effects of witchcraft destroying them in the cross of Christ.
We pray for the restoration and blessing of X in accordance with the Scriptures especially Ephesians 1:3 that says we have been blessed with every spiritual blessing in the heavenly realms. We pray for the blessings of Abraham that are ours in Christ (Galatians 3:8-29) to be appropriated by X and given to him/herin abundance. We especially pray for the blessings given to all humans at Creation - that of fruitfulness, multiplication and dominion. We out bless all the effects of the curse and by the power of God we turn the curse into a blessing.
We ask Jesus to minister to all the places in X's life that the Devil has cursed. We ask for healing of body, mind and spirit and restoration of life and a just, fair and blessed prosperity in Jesus name. Amen. You may need to do this three or four times. I have seen it work powerfully and bring peace to many.
Hexes & Spells
If you think your property may have been affected by a "hex" e.g. your computer or car inexplicably plays up then simply pray over it in the name of Jesus. Remove all items associated with the occult e.g a lucky charm in the car. (see Deut 7:24,25). Pray something like "In the name of Jesus I remove the effects of any hex or spell."
Spells cast on persons are not an area I have had much to do with but they seem to involve confusion, often involve a "floating" mental state, sometimes a loss of memory during which actions are performed and a weakening of the person's will so they are easily seduced/manipulated etc. Others are like a sharp stabbing pain in the head or abdomen that is without medical explanation and which is emotionally distressing. Drug addiction may sometimes be associated with occult activity and casting of spells against people.
Again the solution is to form a believing prayer group, and break the spell by applying the cross to the problem. Something like "Our son Jim seems to be being manipulated by witchcraft and may be under a spell Lord, therefore in the name of Jesus we break all spells and hexes, renounce all vows and free him from all occult bondages for the person you set free is free indeed. Free his will from the dominion of Satan and make him strong and full of the light of the Lord. In Jesus name. Amen." You can ask God to reveal the problem if you are unsure. Use the long prayer on curses as a model for how to pray in these other areas as well.
