Many times throughout my life, in times of trouble or crisis, I've had people come up to tell me, "We're praying for you." And of course, I would never be rude enough to say "Don't bother, if the cancer hasn't responded to chemotherapy, it probably won't respond to mindless chanting", so I thanked them for their efforts. And I never wanted to be entirely negative and say the prayers won't work, on the off chance they might, but now I know different.
According to a study funded by the John Templeton Foundation,prayer had no effect in the recovery of patients. Patients actually did worse if they knew that people were praying for them. Of course, prayer advocates will tell you that prayers were answered, only in the negative, I say if God has already decided whether a person will live or die, the prayers of strangers won't change his mind.
So the next time someone says they're praying for you, what should you do? Thank them for their concern. because it's nice to know that in this selfish and self-sentered world, there are still those who are concerned with others.
