Edna Hong, in her book, "Bright Valley of Love," tells the true story of a young boy with multiple disabilities in Germany by the name of Gunther. He heard about Jesus for the first time at about six or seven years old, when he was brought to a Christian orphanage.
But just as he was about to celebrate his first Christmas, his first and best friend, Kurt, died. Gunther was just learning to talk, but he cried out, "There's a crack in everything. There's a crack in everything," and, sobbing, he continued, "What's so great about Christmas?"
The man the children called Uncle Pastor sensed Gunther's cry for help, so full of pain, and he asked if the other children could answer Gunther's question: "What's so great about Christmas?"
One little girl answered, "Christmas is so great because God sent his son, Jesus, to be our Savior."
"That is true," said the pastor, "But does anyone know why God sent his Son?"
A little girl, Leni, thought for a while, and finally she shouted triumphantly, "Because... because... everything has a crack in it."
Gunther worked as a custodian for over 40 years, and there he died. But he never forgot Leni's reason for Christmas, "Because everything has a crack in it."
