While Jesus was teaching in God’s temple, the scribes and Pharisees brought a woman to him that they said, “was taken in adultery, in the very act” (John 8:4). The religious leaders hoped to trap Jesus in a situation where he would say or do something that contradicted his own teaching and make himself out to be a hypocrite like they were. The men that brought the adulteress to Jesus suggested that she should be stoned according to the Mosaic Law, but Jesus’ compassion for the woman caused him to say to them, “He that is without sin among you, let him first cast a stone at her” (John 8:7). The phrase “without sin” means without any sin. In other words, Jesus was making sinlessness a requirement for executing judgment against the woman that had committed adultery. It says in John 8:9, “And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst.”

Jesus used the example of these men’s guilty consciences to teach the Pharisees a lesson about his divine purpose as the savior of the world. Jesus said, “I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life” (John 8:12). The Pharisees were used to condemning others for their sins against God, but Jesus wanted them to know that it wasn’t necessary for them to judge lawbreakers. God was able to bring conviction of sin, or give someone a guilty conscience, through the love and compassion of his son Jesus Christ. The two Greek terms Jesus used, phos (light) and scotia (darkness) were meant to show the contradiction between love and hate in our actions toward others. Scotia (skot-ee’-ah) is used of secrecy and describes a condition of moral or spiritual depravity. The men that condemned the adulteress might have been guilty of adultery themselves or some other crime that could be punished by death. It may have been their own guilty consciences that caused them to lash out at this woman and expose her to public humiliation.

Jesus’ statement, “I am the light of the world” (John 8:12) was a declaration of his ability to expose the inner thoughts and feelings of people trapped in a lifestyle of sin. It says in John 8:9 that the men that wanted to stone the adulteress were convicted by their own consciences when they heard Jesus say, “He that is without sin among you.” The human conscience is a mechanism by which God is able to reveal his will to us (4893). The Greek word suneidesis (soon-i’-day-sis) means “co-perception.” Another way of saying it would be to see both sides of the story. We are usually aware of our own thoughts and feelings, but not those of others, and in particular, the thoughts and feelings of God are typically hidden from us or outside of our awareness, but our conscience enables us to see what God thinks about our behavior. After the men that were convicted by their own consciences left the scene, Jesus asked the adulteress, “Woman, where are those thine accusers? hath no man condemned thee?” (John 8:10). The woman’s response acknowledged her submission to Jesus’ authority. She said, “No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more” (John 8:11).
