Then Jesus spoke to them again saying, "I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life." The Pharisees therefore said to Him, "You bear witness of Yourself; Your witness is not true." Jesus answered and said to them, "Even if I bear witness of Myself, My witness is true, for I know where I come from and where I am going; but you do not know where I come from and where I am going. You judge according to the flesh; I judge no one. And yet if I do judge, My judgment is true; for I am not alone, but I am with the Father who sent Me. It is also written in your law that the testimony of two men is true. I am One who bears witness of Myself, and the Father who sent Me bears witness of Me."
So far in the Book of John He has called Himself the living water, bread of life and now the light of life. This is the Christ. He is Life. He alone offers life in a way no other can. His life does not bring continual hunger or thirst. His life is satisfying, fulfilling all needs. The light He shines in the dark places allows us to see what is true. And when we understand truth, we have life.
Again the Pharisees struggled with His words because, despite understanding all their religious laws, they could not see, or did not want to see, that He was who had been written about, prophesied about in their books of the law. There was a connection missing. How could He claim to be God's Son? The audacity! I've had a couple look strangely at me because of my witness! Who do I think I am?
When we come to Christ we become children of God. We are co-heirs in God's inheritance. Jesus and His Father bear witness of this even if others don't understand or are offended by our beliefs.
He/They judge not by the flesh... And as children of God through Christ Jesus, we share in His suffering, persecution. Jesus told us this would happen.
What Jesus gives us is the most special thing we can receive. The living water, bread of life and light of life. They desire all to know and receive this. But we are not to be surprised by what others think or fear them because we are in the protective arms of the Almighty.
Matthew 20:21-22 - “Now brother will deliver up brother to death, and a father his child; and children will rise up against parents and cause them to be put to death. And you will be hated by all for My name’s sake. But he who endures to the end will be saved."
