Dear Heavenly Father. I come to You as Your child, purchased by the blood of the Lord Jesus Christ.
I here and now reject and disown all the sins of my ancestors. As one who has been delivered from the power of darkness and translated into the Kingdom of God’s dear Son, and strengthened by the intercession of the Immaculate Virgin Mary, Mother of God, of Blessed Michael the Archangel, of the Blessed Apostles Peter and Paul, and all the Saints and Angels of Heaven, and powerful in the holy authority of His Name, cancel out, O Lord, all demonic working that has been passed on to me from my ancestors.
As one who has been crucified with Jesus Christ and raised to walk in newness of life, cancel, dear Lord, every curse that may have been put upon me and announce to Satan and all his forces that You, the Christ, became a curse for me when You hung on the cross.
As one who has been crucified and raised with Christ and now sits with Him in heavenly places, I reject any and every way in which Satan may claim ownership of me. I declare myself to be eternally and completely signed over and committed to the Lord Jesus Christ. Father, I ask You to command every familiar spirit and every enemy of the Lord Jesus Christ that is in or around me to leave me and to go where Jesus Christ tells these evil spirits to go.
I now ask You, heavenly Father, to fill me with Your Holy Spirit. I submit my body as an instrument of righteousness, a living sacrifice, that I may glorify You in my body. All this I do in the name and authority of the Lord Jesus Christ.
(Since no one can know for sure what his ancestors may have done, every Christian should pray this prayer. Authorities in Spiritual Warfare report that ancestral issues are the number one cause of demonic harassment in the lives of people.)
