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 came 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.”
Then they said to Him, “Where is Your Father?”
Jesus answered, “You know neither Me nor My Father. If you had known Me, you would have known My Father also.”
These words Jesus spoke in the treasury, as He taught in the temple; and no one laid hands on Him, for His hour had not yet come.
Then Jesus said to them again, “I am going away, and you will seek Me, and will die in your sin. Where I go you cannot come.”
So the Jews said, “Will He kill Himself, because He says, ‘Where I go you cannot come’?”
And He said to them, “You are from beneath; I am from above. You are of this world; I am not of this world. Therefore I said to you that you will die in your sins; for if you do not believe that I am He, you will die in your sins.”
Then they said to Him, “Who are You?”
And Jesus said to them, “Just what I have been saying to you from the beginning. I have many things to say and to judge concerning you, but He who sent Me is true; and I speak to the world those things which I heard from Him.”
They did not understand that He spoke to them of the Father.
Then Jesus said to them, “When you lift up the Son of Man, then you will know that I am He, and that I do nothing of Myself; but as My Father taught Me, I speak these things. And He who sent Me is with Me. The Father has not left Me alone, for I always do those things that please Him.” As He spoke these words, many believed in Him.
Who is this Jesus? What does he do? Where did he come from? What is his purpose? These are the questions; the answers are here. He says he is light and those who follow him will not walk in darkness. There is the darkness of the night with lack of light, darkness of a closed room in which no light can be found, darkness of a closed mind in which no understanding can be found, darkness of the soul with lack of light that comes from love. For each condition, Jesus says he is light. He says belief in him brings light and that light brings life. God led the Israelites in the wilderness with a cloud by day and a pillar of fire by night. His light led them and they followed. They demonstrated trust when they followed. Light begins with trust. We trust light will come when we flip the switch. Light implies clear knowledge and understanding when in the light. We can see where to walk when the light is on.
When Jesus’ testimony is challenged for validity, he tells us he is not alone, the Father is with him. His origin is from above while ours is from below. He was sent to us from the Father, we are the Father’s creation from the earth. We are in need of release from the darkness our sins place us in. Belief in Christ grants us that release. As Jesus states he does what the Father tells him, so we tell what he has told us. As Jesus states his purpose is to be lifted up for us in obedience to the Father’s will, so our purpose is to do as Jesus commands and share what we know and trust with others. Not to manipulate but that they may also walk in light rather than darkness. The sharing is an act of love with concern for the other, that and no more.
