Sometimes we have uninvited guests that want to wreak havoc in our lives but with a little discipline, we can prevent that.
Any oil you have will do as long as you ask Father God, I chose to refer to Him as Abba, to anoint it with the blood of His precious Son, Jesus Christ.
I prefer olive oil or the anointing oil I have from Israel.
Rub a little on your hands, start at the lower level of your home and work your way up, touching every possible entry point a spirit could come through such as; a door, window, mirror, computer, TV, or phone, you get the idea. When you touch those surfaces speak you will not come through the blood of Jesus. Not that you have to do it like I do or get religious about it. You are simply setting up barriers that evil spirits know they are not allowed. Someone will likely say I thought a spirit can come through a wall? Yes, that is true they can but our entrances are normally the places we have to give an open door to the enemy and we are standing our ground and taking authority by doing such. Feel free to anoint every wall in your home, there is nothing wrong with that. After all, you simply touch with a fingertip a small amount of oil and it will not hurt to anoint any area you feel led to do. Just last Sunday we anointed the house and Monday morning this impression was on the basement door.
