I have the pleasure of living near one of those churches with the signs out front. The messages are very occasionally advertising actual church business, like Vacation Bible School or special holiday services. But most often, they're that kind of punny or pithy message seemingly aimed at non-believers, trying to get us to come to the church. My dear friend and I love to drive by and read those messages, often sending those messages to each other if they really catch our fancy (meaning our funny bone).
"If you're dead and it's still hot, it's too late."
I kinda want to go find whoever is in charge of this sign and offer them some free marketing advice. I feel like I'm at least part of their target audience with this sign. So there's a part of me that wants to let them know how woefully off-the-mark they are if they really want to try to convince people to come to Jesus. Threats of burning in hell pretty much stop working to convert people once they get past age 10 or so. So telling people that they should come to worship your god because if you don't, said god will condemn you to an eternity of hell is not effective marketing. Maybe just focus on the love part, not the "or else" part.
But if I gave them advice, they might come up with better signs and then I'd lose my weekly chuckle.
