I read the true story once about a woman who was babysitting for the 2 year old son of her preacher. The boy was sleeping in her home one night while the preacher and his wife were out of town and the boy woke up at 4:30 a.m. crying for his daddy.
“I didn’t know what to do until I remembered my tape player. I got up and plugged it in. Together we listened to one of his dad’s sermons. The little fellow knew it was his father’s voice, and went back to sleep.”
