No matter how many times you guess about when the world will end, you can only ever be correct one time. So what is there to gain from all this guessing? What's the point?
Instead of wildly guessing about possible dates for the apocalypse, why not make it a point to declare in public only those things which we know are verifiable and well-attested in Scripture? Why not use the public square for more fruitful discussions and interactions that actually increase our trustworthiness as representatives of God rather than destroying it?
