I found the most condensed essence (also parody) of religious arguments for fatalism in Greg Egan's Permutation City:

Even though I know God makes no difference. And if God is the reason for everything, then God includes the urge to use the word God. So whenever I gain some strength, or comfort, or meaning, from that urge, then God is the source of that strength, that comfort, that meaning. And if God - while making no difference - helps me to accept what's going to happen to me, why should that make you sad?

Logically irrefutable, but utterly vacuous...
