Summary: There is someone who understands! There is someone who cares! While there are people ready to throw stones, ready to condemn, but Jesus is there ready to offer forgiveness and love!
Now early in the morning He came again into the temple, and all the people came to Him; and He sat down and taught them.
Then the scribes and Pharisees brought to Him a woman caught in adultery. And when they had set her in the midst,
they said to Him, “Teacher, this woman was caught in adultery, in the very act.
Now Moses, in the law, commanded us that such should be stoned. But what do You say?”
This they said, testing Him, that they might have something of which to accuse Him. But Jesus stooped down and wrote on the ground with His finger, as though He did not hear.
So when they continued asking Him, He raised Himself up and said to them, “He who is without sin among you, let him throw a stone at her first.”
And again He stooped down and wrote on the ground.
Then those who heard it, being convicted by their conscience, went out one by one, beginning with the oldest even to the last. And Jesus was left alone, and the woman standing in the midst.
When Jesus had raised Himself up and saw no one but the woman, He said to her, “Woman, where are those accusers of yours? Has no one condemned you?”
She said, “No one, Lord.” And Jesus said to her, “Neither do I condemn you; go and sin no more.”
They didn’t care about woman, their interest in her was to trap Jesus…She was a throw away, she was like a piece of trash, but people do the same in the society we live in, we have people in this world that if the baby may have a deformity, they terminate the pregnancy! If the elderly becomes a embarrassment, they put them in nursing home and never visit them. There are people who move from one relationship to another, never making a commitment to one person!
If they don’t want a child, they send them to a foster home or a state faculty or let the grandparents raise the child. If that’s not bad enough we have people that live in this world, who throw babies in dumpster, or bury them in shallow graves!
The significance of Him writing goes back 4000 years to Exodus 31:18 (quickview)  where we read, "When the LORD finished speaking to Moses on Mount Sinai, he gave him the two tablets of the Testimony, the tablets of stone inscribed by the finger of God." The finger that wrote in Jerusalem’s sand had written on Sinai’s stone tablets!
Thank God, this Lawgiver was writing a new law-the Law of Grace!
The other thing that is important about Him writing in the sand is; That He could have easily wrote their sins in stone, so that everyone could see, so that it was permanent, but what ever He wrote, He wrote in the sand, and in sand, just like that, with one wipe of His hand it would be removed, just like their sins, if they would repent.
"He painted a sign advertising the pups and set about nailing it to a post on the edge of his yard. As he was driving the last nail into the post, he felt a tug on his overalls. He looked down into the eyes of a little boy.
“Can I have a puppy?”
"’Sure,’ said the farmer. And with that he let out a whistle. ’Here, Dolly!’ he called. Out from the doghouse ran Dolly followed by four little balls of fur. The little boy pressed his face against the chain-link fence. His eyes danced with delight.
