Just a Son's Portrait

This story was told at church, and was so touching.
This father and son loved paintings and evidently were well off to afford the high priced originals. For years they collected them and had so many that they displayed them all through out their mansion. When the father's son was old enough he was called to serve in the military. While over seas he met this other boy who loved to paint and they became best friends. While serving to pass time away the friend asked if he could paint the wealthy friends portrait. So he began to paint and as time passed he finished his painting.
One day as they began to fight in the battle the wealthy boy was killed when he took a bullet trying to save his friend from being killed. The boys father was devastated when hearing the news of his only sons death. Months passed and one day a young man came to visit the father of the fallen solider. He knocked on the door and the father greeted the visitor and the young man explained who he was and that his son saved his life that day. So as he entered the father's home the young man handed the man a package, when he opened it the painting of his son was unwrapped. The father was so happy and cried with excitement.
As the years passed, the father died and had no one to leave all his paintings and riches to so they began a auction to get rid of all the mans paintings and property.
As the auction began the first painting was the sons portrait. The crowd was not happy that the first painting was that of the man son. No one wanted to bid on that painting and they started yelling that they wanted the high priced painting to bid on not the painting of the mans son.
So all of a sudden a bid was yelled out for $10.00 and there was no other bid as the crowd wanted that painting gone so they could start on the others. As the auctioneer pounded his gavel, "sold for $10.00". The bidder was the yard keeper at the wealthy mans home. As the yard keeper came to get his painting of the mans son the auctioneer folded up his book and told the remaining people that the auction was over. They were all very angry and upset, but the auctioneer told the crowd that the man wanted this to be the secret and he was not able to tell, that who ever bid and got the son portrait would be the one who got the whole entire collection and his estate.
I know this story has a meaning and I guess there could be many. I took it as, you never know what something you might think is worthless could become something so priceless. Like the birth of our Lord and Savior. Born in a stable such a lowly place and the manger was his bed and it was full of hay. Who would of ever thought this precious baby born on Christmas day would become the King of Kings and the savior of the world?
