Those who leave God and his morality out of the equation are missing a significant point, as we see below:
Benjamin Rush, a signer of the Declaration of Independence who was also known as the “Father of Public Schools,” once had this to offer:
“The only foundation for a republic is…religion. Without it there can be no virtue, and without virtue there can be no liberty.”
Don’t miss the significance of that last statement: “..without virtue there can be no liberty….” The principle is clear – a lack of virtue engenders bondage. As one writer noted, “Intemperate men can never be free because their passions give rise to their fetters (bindings).” The more liberties a godless people achieve, the more enslaved they ultimately become in their worldly obsessions.
Still another founding father, the Reverend John Witherspoon, mirrored Benjamin Rush when he declared, “…
Civil liberty cannot long be preserved without virtue….”

We look at the moral degradation of Rome and other societies which went down the tubes, and the same in America, where we are slowly losing our liberties, and the message becomes even clearer. Without Godly virtue, liberty is fleeting. If society doesn't lose it on their own, God will step in when immorality gets too far out of line (note Sodom and Gomorrah, the moral degradation in Israel when it was sacked, etc.), and levy his judgment.
