After removing and destroying all objects of false worship, pray this prayer aloud in every room if necessary:

Heavenly Father, I acknowledge that You are the Lord of heaven and earth. In Your sovereign power and love, You have given me all things to enjoy. Thank You for this place to live. I claim my home as a place of spiritual safety for me and my family and ask for Your protection from all the attacks of the enemy. As a child of God, raised up and seated with Christ in the heavenly places, I command every evil spirit claiming ground in this place, based on the activities of past or present occupants, including me, to leave and never return. I renounce all curses and spells directed against this place. I ask You, heavenly Father, to post Your holy, warring angels around this place to guard it from all attempts of the enemy to enter and disturb Your purposes for me and my family. I thank You, Lord, for doing this in the name of the Lord Jesus Christ. Amen.
