I hear Catholics and other Christians talking about prayer a lot, asking people to pray for them, but I doubt that most truly believe in prayer.
For example, a Catholic friend recently asked for people to pray for her because she was about to undergo surgery to cure a medical condition. I find that amazing. If she really believed in the power of prayer, why would she undergo surgery? Prayer by itself should be enough. Is the thought that God has the power to cure, but only if he has the assistance of a mortal physician? He can’t cure by himself.
On the other hand, I see Christian Scientists as true believers in prayer. They will actually receive prayer in lieu of modern medical techniques that have been proven to cure the ailments that affect us. They truly believe in the power of prayer.
