The founders of our nation were the most insightful, perceptive group of political thinkers and practitioners the world has ever seen. They were very perceptive in understanding the role faith and religion, e.g. Christianity, played in securing political and social freedom.
Shortly before the of signing of the Declaration of Independence, John Adams wrote:
Statesmen, my dear Sir, may plan and speculate for liberty, but it is Religion and Morality alone, which can establish the Principles upon which Freedom can securely stand. The only foundation is pure Virtue, and if this cannot be inspired into our People in a greater measure, than they have it now, they may change their Rulers and the forms of Government, but they will not obtain a lasting liberty.
Adams is basically saying that liberty and freedom are dependent on virtue which in turn is dependent on Christianity. As the role of faith recedes in our state and nation it's only a matter of time before our freedoms are diminished as well. One way that is happening today is the call for government to take on ever bigger role in society. Health care, banking, auto companies, businesses, retirement, education, welfare and so forth are increasingly coming under the control of government. We look to government rather than God as the source of our well-being. Ultimately, this stems from jettisoning the belief that God rules over the universe and we owe our first allegiance and duty to Him. Failure to do so, means losing not only our freedoms but achievement of a better society which we thought we could achieve in the first place.
