The Healing
Jim and his wife, Connie, were shocked by the loss of their four-month-old son—Joshua, whose life was taken by SIDS—sudden infant death syndrome.
Thirty hours ago, Jim drove to the baby-sitter’s home to      Joshua. It was a     trip, like the one he made five days every week. He arrived, and little Joshua could not be        from his nap. The next few hours were a time of life and death: the racing ambulance, swift-moving doctors and nurse. But 12 hours later, at Children’s Hospital,      the doctors had exhausted（用尽） all     , little Joshua was gone. Yes, they wanted       of Joshua’s usable organs to be donated.

The       stopped and stood motionless. Finally she spoke, but it was only a whisper. “You’re not going to believe this. But about an hour ago the customer sitting in this chair wanted me to hurry       she could get to Children’s Hospital. She       here so full of joy. Her prayers had been answered. Today her baby granddaughter is receiving a     needed transplant—a heart valve.”
Jim’s healing began.
