1. For protection from God that they might do no harm upon you and lose their obsession.
2. For the strength to fight them that you might not be a coward unable to stand your ground against them.
3. For a change of heart, that they might let go of their evil ways, and become not your enemy but your friend and advocate.
This is what I pray when I am forced to fight my enemies who just won't leave me be in peace and make it their business to ruin my life and to work evil influences to darken my mind. These three requests held sternly in the heart I believe cover all ground and justify me.
