On October 20, 2006, a middle-aged auto mechanic, Jeff Markin, walked into the emergency room at the Palm Beach Gardens Hospital and collapsed from a massive heart attack. Forty minutes later he was declared dead. After filling out his final report, the supervising cardiologist, Dr. Chauncey Crandall, started out of the room. Before I crossed its threshold, however, I sensed God was telling me to turn around and pray for the patient, Crandall says.

With that prayer and Dr. Crandall's instruction to give the man what seemed one more useless shock from the defibrillator, Jeff Markin came back to life - and remains alive and well today.

But how did a Yale-educated cardiologist whose Palm Beach practice includes some of the most powerful people in American society, including several billionaires, come to believe in supernatural healing?

The answers to these questions compose a story and a spiritual journey that transformed Chauncey Crandall.
