Christian groups in London have decided not to turn the other cheek: In response to a much-publicized ad campaign by atheists on city buses, the groups plan to take out ads of their own in the next two weeks, the Guardian reports. Their theological retort, delivered via mass transportation, will argue: "There definitely is a God. So join the Christian Party and enjoy your life."
It's a direct response to the atheist ad slogan: "There's probably no God. Now stop worrying and enjoy your life."
