Perry,
If God owes us nothing, then I owe nothing to my children.
The moment I learned of the conception of both of my children I knew I had the biggest reponsibility and that as good a parent as I could be, they will owe me nothing. It is my obligation to care for them, I am doing no favor to them. Similarly, if God puts us here on Earth, then he owes at least a very basic care. Just tell us that you exist and the nature of our relationship with Him. I like the God of Einstein and Spinoza, a God of the natural order of the Universe who never interferes for good or ill in human affairs. That's the only way my life has any meaning.
A god that saves a person in a hospital (my dear one for whom I prayed) while millions of innocents die in wars, of famine, or by natural disaster makes no sense. It's plain stupid. Especially considering that years later I will pray for that same person and my prayer won't work. WTF. My prayers are supossed to get better with experience and yet seems to be quite the opposite. Is it possible that the natural order works (aging and decay) and that this idea of a God intervening in human affairs is just an invention by the superstitious, weak or self-righteous. The evidence indicates so.
If we replaced all the praying time for hours of study in the medical field we would be more effective in saving lives. Centuries ago people pray a lot more than they pray today and yet life expectancy has gone up. Isn't that evidence that the idea of God only serves as a psycological boost to the sick, but it is a waste of time when performed by others for the "benefit" of the sick person.
