Prayer Vs Work

In my youth I was promised that as long as I was a good person, God would help me when I needed him. But, I always asked, "Where was God when my mother had lost both of her kidneys? Where was God when my father couldn't find any work? Where was God when my mother died?" and, yes, my family was religious and all prayed for help.

Now some of you christfags will say "It was God's plan" but that doesn't mean anything when you also say that if you pray, God will help you. If God just follows his plan, then what is the point of prayer. Because, if you pray, and you believe, God says he will help you. But, if it was part of God's plan, then he wont help even if you pray.

Therefor, even to christfags, prayer does nothing.

Or let me ask another question:
Can God create a rock so heavy not even he can lift it?

If you answered yes, then you just said God can't lift that rock, and is therefor not omnipotent.
If you answered no, then you just said God can't create that rock, and is therefor not omnipotent.

And, if God is not omnipotent then he is not God.
