Jesus did not pick up the stones.
John 8:7 So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.
The crowd had gathered to bring this woman to Jesus to condemn her, yet when the Lord brought out all condemnations of everyone, her alone was left standing with Jesus. People may be able to bring up your past and the wrongs that we have done, but when it comes down to it we will all stand alone with Jesus. Notice that Jesus though spotless and perfect without sin, did not Himself pick up the first stone. He could have but He choose to show compassion instead of condemnation. May we not become so quick to pick up the stones.
