"I knew Charlie so deeply, in a way no one else could," Erika Kirk writes in the book's forward. "That is why I can say with certainty: these pages are not theory for him, they are testimony." (Win McNamee/Getty Images)

Erika Kirk, the now-CEO and board chair for Turning Point USA, goes on to thank readers for "opening these pages, for allowing Charlie’s words and convictions to take root in your own life, and for helping to carry forward the legacy of a man who poured himself out for his Savior, his family, and his country."
Charlie Kirk was killed in September as he spoke to a crowd at Utah Valley University. Authorities believe a single shot was fired from the roof of a building some 200 yards away.
Charlie Kirk was 31, and the married father of two young children. The assassination of Charlie Kirk, one of the most prominent conservative voices in the country, sent a shockwave across the nation and mobilized thousands of young supporters on college campuses across the United States.
Fox News Digital also exclusively obtained the prologue and introduction of the book, written by Charlie Kirk.
"In this book, I intend to persuade you of something that may, at first, seem quaint, old-fashioned, or even unnecessary: that the Sabbath is not merely a helpful tradition or a cultural relic—it is essential to the flourishing of the human soul," Charlie Kirk wrote.
"I will define the Sabbath not just in doctrinal terms but in existential ones. We will explore its origin—not in history, but in eternity; not in law, but in creation," he wrote. "I will show you how to incorporate it not as a weekly burger but as a life-giving rhythm that reorders your time, renews your mind, and restores your humanity."
Charlie Kirk wrote that the book "is not written for the religiously initiated alone."

The introduction of the book, in Charlie Kirk's own words, brings the reader on his own journey to rediscovering the Sabbath.
Charlie Kirk brings the reader back to the summer of 2021, saying his life was "in perfect order," and after marrying Erika Kirk, his life "was as good as it gets."
"But on the inside, there was a battle brewing," he wrote. "I was fatigued, tired, and spiritually confused."
Charlie Kirk discussed how he began to unplug, recharge and reconnect with God, family, and himself through observing the Sabbath.
The book is packed with Charlie Kirk's practical insights and spiritual wisdom to help readers understand how honoring the Sabbath "restores balance, reduces anxiety, and nourishes your soul."
