I mean it.
Any ideas? Give free groceries in a lower-income neighborhood? Go to a gay bar and tell people how much Jesus loves them? Pass out school supplies to needy kids? Give free bibles? (Side note: when purchased in case quantities, the cost per bible is about one-third that of a chicken sandwich.)
These things have all been done on a small scale from time to time. But now we know we can mobilize as a nation. What can we do that will make a positive difference, all in one day? Something that focuses on Jesus and not an "issue"?
Then, we need a celebrity Christian with a Huckabee-like following. Not that I know any.
