The only thing that can be changed is the mind. Jesus teaches us in A Course in Miracles Workbook Lesson 7, "I see only the past." (W-7) The world is a projection from wrong-minded perception that has already past. It's like watching a film that's "in the can," so talking back to the movie screen is ridiculous because what you are speaking to are merely shadows. You can always have a change of mind, a state of peace, and an alignment with the Holy Spirit. Letting the Holy Spirit manage your mind will take you into divine providence!
