Early one Friday morning two years ago, David Diaz woke up his wife, Marisia, and told her he didn’t feel right. He asked her to pray with him. Their son called 911, and within minutes, Marisia was tailing an ambulance down the dirt road away from the couple’s house on the outskirts of Phoenix to a hospital in the city. David had had a massive heart attack.
Before being wheeled into surgery, he whispered the PIN for his bank card to Marisia, just in case. But the double-bypass operation was successful, and two weeks later he was discharged.
