Letters form Heaven

An except taken from the website The Post-Rapture Post:

"Just write your letter and it will be hand-delivered immediately following the exodus of the pure from the Earth. But you must be thinking to yourself, "How can the letters be delivered after the Rapture?" The answer is simple. The creators of this site are Atheists. That's right, we don't believe in God. How else would we be able to deliver your correspondence after the Rapture?"

Regarding of the nature of this civic initiative, I recommend to check out the FAQ they provide. First might be a joke to laugh on, but on the second, it seems rather to be a satirical attempt to shake people, and raise some money on real charity - which is an interesting shift from being a mocker to being a critique of a social interaction.
Another satirical attempt by atheist, misused by believers, but still interesting example of satire in action.
