I liked the story I once heard about a fire-and-brimstone street preacher. He was just winding up to the climax of his peroration by painting a lurid picture of hell’s torments, which he capped with the words: "And there will be much wailing and gnashing of teeth", when a voice came back from the crowd: "But I haven’t got any teeth!". Quick as a flash, the preacher responded: "Teeth will be provided!"

I hope this isn’t trivialising a very serious and important discussion.
