Don't let the extreme/secular left know about this one. They don't think any of the Founders or other early American leaders had any intention for this country to be based on Judeo-Christian principles. But hear Daniel Webster:

"If we abide by the  principles taught in the Bible, our country will go on prospering. But if we and our posterity neglect its instructions and authority, no man can tell how sudden  a catastrophe may overwhelm us and bury all our glory in profound obscurity."  

More than a quote, it's prophetic, c. 2009.
