I've been pondering America's past and future. Our forefathers agreed that America could not be great unless it was moral and righteous.
For example, in his Farewell Address, President George Washington warned:
"Of all the dispositions and habits which lead to political prosperity, religion and morality are indispensable supports. In vain would that man claim the tribute of patriotism, who should labor to subvert these great pillars of human happiness, these firmest props of the duties of men and citizens."
