The Gospel truth is under unrelenting attack these days. From The Da Vinci Code to the The Gospel of Judas to even whether a burial tomb actually exists for Jesus, skepticism abounds. Best–selling Christian author John MacArthur says it’s time to take a stand in his new book, The Truth War: Fighting for Certainty in an Age of Deception.

MacArthur wants this book to wake up today’s Church. He points a finger specifically at the Emerging Church movement for its compromise with a postmodern society that embraces religious pluralism and the rebirth of Gnosticism.

“Certain avant–garde evangelicals sometimes act as if the demise of certainty is a dramatic new intellectual development, rather than seeing it for what it is: an echo of the old unbelief,” MacArthur writes. “It is unbelief cloaked in a religious disguise and seeking legitimacy as if it were merely a humbler kind of faith. But it’s not faith at all.”

MacArthur says the church must “confront such skepticism” with the Word of God.

“Faithfulness to God demands it,” he says. “The honor of God requires it.”

While the spirit of the age is to “get along” in all circumstances, MacArthur reminds us how first–century Christians gave up their lives confronting unbelief, a foreign concept to today’s church.

“We must not embrace such confusion in the name of charity, collegiality, or unity,” he said. “We have to stand up and fight for the truth—and be prepared to die for it—as faithful Christians always have.”

MacArthur calls Christians to remember the words of Jude, who warned that false teachers would arise. He also says believers should remain faithful and reach out with the truth to those who have been led astray.

Paraphrasing the Apostle Paul, MacArthur says, “The Truth War” is a good fight.
