Loving this picture!!
Saw it on twitter, no idea where it was taken.
I'm glad to see that there's church with a good sense of humour though. From the background it looks like somewhere in the US, which seems a bit strange.
EDIT: Just checked, and that particular website, which seems to be in America, www.says-it.com/churchsigns
is for people to make up their own virtual signs, so that one isn't genuine - or at least the wording isn't. Still funny though.
