A wise person once said that two hands engaged in labor can accomplish more than a million hands clasped in prayer.
People who are afflicted with religious delusions often believe that they can ask their invisible friend for a favor, and if he is not in a bad mood he just might grant their wish, if he feels like it, and they asked the right way, and they asked the correct invisible friend – the one they imagine exists, not the one those bad people imagine.
Try telling a teenager to pray when their iPod is broken. Try telling a double amputee to pray so that an invisible friend will make her limbs grow back. It is not going to happen. And the reason that it is not going to happen is that Nothing Fails Like Prayer.
