A bit of thread creep coming up ... but, talking of Pearls Of Great Price:

I'm not a believer, I'm agnostic. I also know that if person A can persuade me by argument that something is so, person B can persuade it ain't. Never mind that; I do know that if you're a Christian, you know the most important thing in the entire history of the whole universe, and if you don't want to tell other people about it, you are just plain selfish!

OK, I'm being flippant, but I'm not making fun. People with Faith have a duty to try and spread it. Do it by example instead of by word when folks aren't inclined to listen.
