I don't know what possesses people to continuously forward these e-mails. Well, that's not completely honest. I think their intentions are good. (I think) they want to spread the Message of Jesus.
But spreading the Message this way seems about as smart as sending invites to all your friends in the mail to get them involved with Amway.
On top of that, forwarding e-mails whose veracity you haven't checked (no, this painting is not going to be on a postage stamp), or that accuse me of not loving Jesus (if I don't forward it), seems to be a disturbingly poor way to spread any kind of good message.
With much restraint, I held myself from replying to the e-mail (which was on an e-mail group for our local church), pretending the following story (which I found on snopes.com) was true:
A woman came home to find her husband in the kitchen, shaking frantically with what looked like a wire running from his waist towards the electric kettle. Intending to jolt him away from the deadly current she whacked him with a handy plank of wood by the back door, breaking his arm in two places. Until that moment he had been happily listening to his walkman.
I don't know why, but I think that story is hilarious...particularly imagining that someone would think it might be true.
