Message from God billboards

Back in 1999, a bunch of billboards popped up around Phoenix that had white letters on a black background and were signed by God. One I took a bad photo of said "You think it's hot here? --God." They're back. There's now one near Kat's workplace that says "Life is short. Eternity isn't. --God." These come from a group that calls itself GodSpeaks, which doesn't actually pay for or put up the billboards, they just help interested groups in doing it locally.

I'd like to see someone make one of those sign generators for these billboards, so I can make some parodies, which these are just asking for. These billboards aren't as lighthearted as some of the church marquee signs (like this one, for example, which suggests a God who has mellowed considerably from the one who sent the plagues of the Exodus).

Here are some ideas for better content:

Stop putting words in my mouth. --God

If I existed, I'd communicate directly to all people in their own languages in a miraculous manner rather than through billboards put up by people pretending to be me, just as parents pretend to be Santa Claus. -- God

Please post further suggestions in the comments. (And if somebody writes or finds a billboard photo generator, please let me know.)
