One day, my husband announced to the family that he was going to fast and pray. Ginny, our 5-year-old, had recently learned that fasting meant not eating. "No!" she shouted. "You can't fast! You'll die!" Her dad carefully explained that many men and women fasted in Bible times. Ginny paused a moment. Then, with a flash of insight and a note of warning, she proved her point. "And they all died," she said.
