I can be hurt by nothing but my thoughts.

Father, Your Son is perfect. When I think that I am hurt in any way, it is because I have forgotten who I am, and that I am as You created me. Your Thoughts can only bring me happiness. If ever I am sad or hurt or ill, I have forgotten what You think, and put my little meaningless ideas in place of where Your Thoughts belong, and where they are. I can be hurt by nothing but my thoughts. The Thoughts I think with You can only bless. The Thoughts I think with You alone are true. I will not hurt myself today. For I am far beyond all pain. My Father placed me safe in Heaven, watching over me. And I would not attack the Son He loves, for what He loves is also mine to love.
