When the Pharisees brought their double-edged question to Him, instead of answering right away, Jesus bent to the ground and began writing in the dirt. After at time, he stood, gave his famous phrase, and then returned to writing. I remember a sermon from years ago that posited that Jesus was writing down the sins of the men who had seized the woman they wished to stone.
Since hearing that idea, I have grown to like it more and more. Here are these people who stand in judgement against this woman and who are trying to trap Jesus into siding with either the laws of Rome or the laws of his religion, and instead of answering, He begins to write down their hidden sins. Now, I don't believe that He would be so gauche as to identify which person corresponded to which sin, but I believe that, as they became curious about what He was writing, they craned their necks to look. When He stood to give His famous line, I can imagine Him meeting the eyes of each man and then back down to what He had written. As they followed His gaze, their faces would pale. When He returned to writing, they would slink away in shame.
I love that He looks up after a moment, finds Himself alone with the woman, and feigns confusion. "Did no one condemn you?" When she answers in the negative, He gives the line that gives me hope for my own soul: "Neither do I condemn you. Go on your way. Sin no more."
I kind of hope that, as He stood to go, He then also wiped away the sins He had written in the dirt as well.
