It was a cold day in December in New York City. A little boy about ten years old was standing in front of a shoe store on Broadway. He was looking through the window, bare footed and shaking with cold. A lady walked to the boy and said, "My little boy, what are you looking at?  I was asking God to give me a pair of shoes. " was the boy's reply.

The lady took him by the hand and went into the store. She asked the clerk to get a pair of socks for the boy. She then asked if he could give her a basin of hot water and a towel. The clerk quickly brought them to her. She removed her gloves, knelt down, washed the boy's little feet, and dried them with a towel. By this time, the clerk had returned with the socks. The lady put on the socks for the boy, and then bought a pair of shoes for him. She patted him on the head and said, "My little boy, do you feel more comfortable now?"

As the lady turned to go, the boy caught her by the hand suddenly and looked up in her face.

With tears in his eyes, he asked her, "Are you God's wife?  No, I'm a mother," said the lady.
