Why did Jesus write on the ground?

An interesting thought came up today as I was browsing around some spiritual sites - one of which was a group site for my Association. One of the members was reading the Bible Lesson for this week, and the story of the adulterous woman is featured (see John 8:3-11).

The question posed was why did Jesus write on the ground? Here is my take on this.

He knew that those who asked him "what sayest thou," were the Pharisees and scribes who were looking to accuse Jesus of wrongdoing - they already had the thought in their heads. When they said the law dictated that the woman should be stoned to death, that was the thought they already had.

Jesus stooped down and wrote on the ground. I took this to be a metaphor for the treatment of mortal mind he was giving to everyone present. He wrote the Christ into the ground, which represents the mortal, carnal mind (remember "ashes to ashes, dust to dust" signifying where mortal man - Adam - came from), that which sins. Then, he stands up and says, "He that is without sin among you, let him first cast a stone at her." That writing of the Christ on mortal mind unveiled the sins and brought everyone face to face with their past errors, and every one was then "convicted by their own conscience," and left without stoning the woman, leaving her with Jesus alone.

Jesus once again "wrote" a masterpiece.
