i ruminated for hours before making the OP!
A question I considered was
Couldn't people just read the Bible? Wouldn't that be enough?
Here's how I'm looking at it.
If you get a disease, you pray for healing, and you go to the doctor.
So read the Bible for the spiritual view, and read other books because the Bible probably wasn't intended to be read in a vacuum.
Here in America just about every issue you can filter first through the Bible, then what does history teach on the subject and then what does our Constitution say on the subject.
The Bible as absolute truth, history doesn't lie and can show what good and bad decisions have led, and our Constitution I could easily say is the 2nd greatest governing document given to man by the hand of God
George Washington addressing delegates at the Constitutional Convention. He said,
“If to please the people we offer what we ourselves disapprove, how can we afterwards defend our work? Let us raise a standard to which the wise and honest can repair; the event is in the hands of God."
It appears to me, then, little short of a miracle, that the Delegates from so many different States (which States you know are also different from each other in their manners, circumstances and prejudieces) should unite in forming a system of national Government.”
— George Washington (1732-1799) Father of the Country, 1st President of the United States
The convention by whom that constitution was formed were of opinion that the gospel of Christ, like the ark of God, would not fall, though unsupported by the arm of flesh ...”
— John Jay (1745-1829), Founding Father, Patriot, Statesman and First Chief Justice of the Supreme Court
The United States Constitution has proved itself the most marvelously elastic compilation of rules of government ever written.
-Franklin D. Roosevelt
This by no means is it arrogant or prideful to say that America is exceptional. For the Constitution to last for 300 years, the prosperity and freedom that it has built and protected is evidence enough to make this statement true.
French political scientist and historian Alexis de Tocqueville was the first writer to describe the country as "exceptional" in 1831 and 1840. After his country experienced a very violent and failed revolution, Tocqueville was to America to see what why was it so prosperous.
Christianity is the companion of liberty in all its conflicts - the cradle of its infancy, and the divine source of its claims. -Alexis De Tocqueville
Alexis de Tocqueville wrote:
Upon my arrival in the United States the religious aspect of the country was the first thing that struck my attention; and the longer I stayed there, the more I perceived the great political consequences resulting from this new state of things. In France I had almost always seen the spirit of religion and the spirit of freedom marching in opposite directions. But in America I found they were intimately united and that they reigned in common over the same country.
-Alexis De Tocqueville 1831.
