So what is it? Is prayer the power of the mind, or are religious folks simply not praying for anything that the mind and modern medicine cannot fix? Another example can be starvation. It is not the fault of man that people are starving all around the world, and even if you could argue that it is, God should have the ability to feed them and not punish them for the evil nature of others. Yet, the hungry stay hungry. So, why are the religious not praying for them? Well, they are, but the power of the mind cannot feed entire countries.
What it comes down to is either that God is simply in the mind, or he has very screwed up priorities. I mean, if God will get rid of your flu but not help feed the hungry, is that really an entity worth honoring?
