The story goes that some time ago, a man had a very lovely little daughter. One day the man punished his 3-year-old daughter for wasting a roll of gold wrapping paper. Money was tight and he became angry when the child tried to decorate a box to put under the Christmas tree. But the little girl brought the gift to her father the next morning and said, “This is for you, Daddy.”

The man was embarrassed by his earlier act, but his anger broke out again when he found out the box was empty. He shouted at her, saying, “Don’t you know, when you give someone a present, there is supposed to be something inside?” The little girl looked up at him with tears in her eyes and cried, “Oh, Daddy, it’s not empty at all. I blew kisses into the box. They are all for you, Daddy.”

The father was ashamed. He put his arms around his little girl, and he begged for her forgiveness.

Only a short time later, an accident took the life of the child. It is also told that her father kept that gold box by his bed for many years and whenever he was discouraged, he would take out an imaginary kiss and remember the love of the child who had put it there. In a very real sense, each one of us, as human beings, has been given a gold box filled with unconditional love and kisses… from our children, family members friends and God. There are simply no other things anyone could hold, more precious than this.
