God who gave us life gave us liberty. And can the liberties of a nation be thought secure when we have removed their only firm basis, a conviction in the minds of the people that these liberties are a gift from God? That they are not to be violated but with His wrath? Indeed I tremble for my country when I reflect that God is just, and that His justice cannot sleep forever.
Thomas Jefferson
Notes on the State of Virginia, Query XVIII, 1781
This is a useful corrective to those who present Thomas Jefferson as sort of a proto-atheist or secular humanist.
