God bless you and greetings in the name of Jesus Christ who declared he was the light of the world (John 8:12).
The beginning of John 8 sets the stage for Jesus’ wonderful presentation of who he was. He was gathered in the temple early in the morning teaching those who came to hear what he had to say. The scribes and Pharisees interrupt his meeting and demand he deal with an adulteress. He is not shaken; he delivers the woman and continues teaching the people.
John 8:12:
Then spake Jesus again unto them [the people], saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
It’s “Show & Tell” time! He has just delivered this lady, and everyone has seen it. Now he’s going to tell them about it. Jesus returned to teaching the people, and this incident instigated by the Pharisees provided a great example that he used to communicate who he was and what he could do for them.
He was the light of the world, and he was willing to enlighten them. When Jesus spoke of himself as the light of the world, he was declaring that he was the Messiah (Isaiah 9:1-2; 42:6-7; 49:6b-7; Matthew 4:14-17; Luke 2:25-33; Acts 26:23). The Pharisees’ reaction to this statement was vehement.
John 8:13-18:
The Pharisees therefore said unto him, Thou bearest record of thyself; thy record is not true. [You liar!] 14 Jesus answered and said unto them, Though I bear record of myself, yet my record is true: for I know whence I came, and whither I go; but ye cannot tell whence I come, and whither I go. 15 Ye judge after the flesh; I judge no man. 16 And yet if I judge, my judgment is true [Was his judgment concerning this woman correct? Absolutely!]: for I am not alone, but I and the Father that sent me [When we walk by the spirit we will be able to say the same thing.]. 17 It is also written in your law, that the testimony of two men is true. 18 I am one [egō eimi] that bear witness of myself, and the Father that sent me beareth witness of me.
Remember the people are still there watching this confrontation. He is standing for the integrity of the Word, and the right of the people to hear it. The Pharisees accuse him of lying, and he is showing the people there how to handle accusation. He is not lying. He is just saying, “I am what the word of God says I am.” Jesus knew that what God said about him in His Word was true. He just declared he was what the Word of God said he was. However, God not only bore witness of Jesus Christ by the words of the Word, He also bore witness in that He worked with Jesus to do the works of God.
Luke 4:17-21:
And there was delivered unto him [Jesus] the book of the prophet Esaias [Isaiah]. And when he had opened the book, he found the place where it was written, 18 The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, 19 To preach the acceptable year of the Lord. 20 And he closed the book, and he gave it again to the minister, and sat down. And the eyes of all them that were in the synagogue were fastened on him. 21 And he began to say unto them, This day is this scripture fulfilled in your ears.
God not only declared in His Word that this is what Jesus Christ would do, but He worked within him to do these very works. Jesus preached the gospel to the poor; he healed the brokenhearted; he set at liberty them that were bruised. Jesus knew that he was who God said he was, and he believed to do what God said he would do. He knew his Father was true and would uphold His Word. What an example he set for us!
