Jesus again speaks to the crowds declaring himself to be the light of the world and that whoever would follow him will never walk in darkness (see also 1 John & Revelation). This bothers the Pharisees. They claim his remarks are not valid because he is the only one making these claims and they are about himself. According to the Law there must be at least two witnesses to any claim. Jesus replies that his testimony is validated by his Father who sent him. He says they don't really know him or his Father. In their own minds they believe themselves to know God because they are descendants of Abraham and they strive to keep the Law of Moses. But, Jesus says basically "I am from above. I have heard from the Father. He is with me. I am going away to a place you cannot come. I have much to say in judgment of you, and you will die in your sins if you do not believe that I am who I claim to be." Many put their faith in him as he spoke.
Everyday we come closer to the time in which we will see and know the Christ for all that he is. He will truly be the light of the world (Revelation 22:5). Until then, there is still a great darkness and night. Multitudes will die in their sins without faith in Christ and his claim to be who he says he is. We have an active role to play in this until that day comes. May the message of hope that is found in Jesus Christ shine as a light in this dark world to lead God's people home.
