Read John 12:44-50

Jesus shouted to the crowds, “If you trust me, you are trusting not only me, but also God who sent me. For when you see me, you are seeing the one who sent me. I have come as a light to shine in this dark world, so that all who put their trust in me will no longer remain in the dark. ” - John 12:44-46 (NLT)

Jesus is not just an enlightened human teacher. He is God incarnate, God in human form. His life and death have accomplished everything needed for our salvation; we have only to trust rather than reject Him. As a light in the darkness of our sinful world, He enables us to proceed safely through this life to the next.
