Is America suffering from a "deep crisis of the soul"?

Christian apologist Ravi Zacharias has warned in an Independence Day reflection that America is suffering from a "deep crisis of the soul," facing the "death of morality" and sliding into a future with no truth or reason.
"Whatever happened to the American soul? We are truly at the cliff's precipitous edge and the fall could be long and deadly. Why? We have a deep crisis of the soul that is killing us morally and we have no recourse," Zacharias wrote in a blog post on his website.
"We are at war but not only with an enemy. We are at war within our own culture, and whether we will ever win over the enemy depends on whether we win this war within our own souls," he added, noting that the United States is battling not only enemies overseas, but is also battling for its own identity.
The Indian-born, Canadian-American apologist warned of the "death of morality, the death of truth; then we come to the last, the death of reason."
"We are sliding into the future with evil stalking us but no morality, no truth, and no reason to guide us. America may be flirting with a self-inflicted mortal wound. Or it could well be a killing that is designed by a postmodern ideology masquerading as political correctness," he continued.
"When liberalism, whose legitimate child is relativism, has played itself out it will be a Pyrrhic victory to find ourselves in the hands of those whose identity is no longer in doubt. And when they are in control, the very means they used to hide their identity will be silenced as well."
Zacharias argued that the only hope for America is to turn to God and His Son, and called on Americans to stop speaking and thinking only in terms of right and left.
"We have forgotten there is an up and a down. May God help us! We need His transforming power to change our thinking and to give us a hunger for what is true. True freedom is not in doing whatever we wish but in doing what we ought," Zacharias wrote.
"That has been buried in America. And only one who knows the way out of the grave can give us a second chance to live: Jesus, the way, the truth, and the life that sets us free from within first, before we learn to deal with the lies around us," he added.
Zacharias has preached at major evangelical conferences on several occasions, and back in January spoke to tens of thousands of young adults at the 2016 Passion Conference in Georgia and Texas.
He recalled that it was the song "Who Will Answer" by Ed Ames in the 1960s that led him to the Bible while he was searching for truth back home in New Delhi, India.
"Young people, truth is the most valuable thing in the world," Zacharias told the crowd, asking, "Does the truth matter to you?"
