On the selves in our homes, we may have some curios that we've purchased from any department store here in America.
Many have bought them in foreign land and place them all around the house. Some homes have Buddha, etc. and crosses with Jesus still on them, which He is not, and numerous other types of items that may be idols.
If there are problems in the home, check to see what is sitting around that may need to be removed or cleansed in the name of Jesus.
