Someone sent me an email asking to pray for a 19 year old friend who has an inoperable brain tumor. I said, "I would pray that she stop thinking in ways that cause a brain tumor. The change has to start with her. Everything else we do is temporary."
People send emails asking me to pray for all kinds of cancer, I say, "I pray that they stop eating junk food. That they start to care about the foods they eat and what they put in their mouths. That they stop living in negativity and stop harboring non-useful grudges."
