Faith was foundational to the United States at three points. The first was winning freedom; just take the enormous influence of the “black regiment,” the preachers and thinkers behind the American Revolution. The second was the ordering of freedom; nothing is closer to the genius of the United States than the First Amendment and its establishing the separation of church and state in such a constructive way. And the third—which is less stressed today— was the sustaining of freedom; refer to James Madison’s argument that faith is vital to virtue, and that virtue is vital to freedom.
As the West declines, says author Os Guinness, Christians will need to be a faithful counter-culture engaged with a world very different than what we’ve known.
