1. Jesus is the light of the world (12-20)

Jesus revealed himself as the light of the world. Without Jesus, we live in the darkness of sin, meaningless and death. But when we follow Jesus, the light, we know God. Our sins are forgiven, and we have eternal life. Jesus promised that we will not walk in darkness anymore. The Pharisees rejected Jesus' testimony about himself. But Jesus is no ordinary person. He is the Son of God and the only one qualified to speak about light, eternal life and heaven. The Pharisees did not accept the weight of Jesus' words for they did not know the Father. They remained in spiritual darkness.

2. The Son of Man will be lifted up (21-30)

Jesus said that he would be going away. This meant he would be returning to heaven. He would soon be lifted up on the cross and die for the sins of all mankind. Then many would know that he is the Messiah who came to save us from our sins. But those who persist in unbelief would die in their sins.
