I didn't throw it back because it has never been anyone but yours. You are the one throwing out those verses attempting to say that they must not be true since amputees who pray to re-grow their limbs don't always get a "yes." Thus, it's your job to show how these verses literally mean that any conceivable prayer request, including the re-growth of limbs, must be granted by God. Unless you can show that it is so, you're just blowing hot air.
I'm a simple man. And like many in the his target audience, I'm not very adept at finding the hidden meaning in the word of the cosmic zombie. When I read that he says one shall receive whatever it is they ask for in prayer, I understand that one shall receive whatever it is that they ask for in prayer. Now I'm no bronze age goat-herder, but I think my comprehension of such a statement is fairly accurate. If my interpretation of the cosmic zombies message is off, either I and millions of others are missing something or the cosmic zombie should have been a bit less mysterious in how he chose to communicate.
And when you say "amputees who pray to re-grow their limbs don't always get a 'yes'" implies that there are amputees who've had their prayer answered. That was a mistake on your part, right?
