Just imagine the impact even if only 25% of churched people are truly born again. Sections of America would be decimated. (I hope it doesn't happen during the evening commute!) Even in less affected places (like NYC or Las Vegas!), still, their communities could lose key government officials, police and firemen, doctors, nurses, first responders, and teachers, resulting in a rapid breakdown of society.
Then, ravaged by crime, hunger, lawlessness, and chaos, those left behind will look for a leader—you might say a savior—to restore order. It's not hard to imagine a scenario in which America submits to the leadership of anyone who promises hope. Even if that person is the Antichrist.
