Knowing The Word: I Am the Light of the World, John 8:12-30

The Old Testament is filled with symbolic images of light. There is the pillar of fire in Exodus 13, David’s assertion that “the Lord is my light” in Psalm 27, the promise in Isaiah 49:6 that the Servant of the Lord will be a light for the Gentiles. Additionally, there is this prophecy from Zechariah (14:7c-9):

Then the Lord my God will come, and all the holy ones with him. On that day there shall be no light, cold, or frost. And there shall be a unique day, which is known to the Lord, neither day nor night, but at evening time there shall be light. On that day living waters shall flow out from Jerusalem, half of them to the eastern sea and half of them to the western sea. It shall continue in summer as in winter. And the Lord will be king over all the earth. On that day the Lord will be one and his name one.

The two symbols of the feast of Tabernacles come together in this prophetic passage, which may have even been read as part of the temple liturgy during the feast. Regardless, we can see in Jesus the fulfillment of this prophecy as he claims to be the source of living waters and the light of the world.

12 Again Jesus spoke to them, saying, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.” 13 So the Pharisees said to him, “You are bearing witness about yourself; your testimony is not true.” 14 Jesus answered, “Even if I do bear witness about myself, my testimony is true, for I know where I came from and where I am going, but you do not know where I come from or where I am going. 15 You judge according to the flesh; I judge no one. 16 Yet even if I do judge, my judgment is true, for it is not I alone who judge, but I and the Father who sent me. 17 In your Law it is written that the testimony of two people is true. 18 I am the one who bears witness about myself, and the Father who sent me bears witness about me.” 19 They said to him therefore, “Where is your Father?” Jesus answered, “You know neither me nor my Father. If you knew me, you would know my Father also.” 20 These words he spoke in the treasury, as he taught in the temple; but no one arrested him, because his hour had not yet come.

21 So he said to them again, “I am going away, and you will seek me, and you will die in your sin. Where I am going, you cannot come.” 22 So the Jews said, “Will he kill himself, since he says, ‘Where I am going, you cannot come’?” 23 He said to them, “You are from below; I am from above. You are of this world; I am not of this world. 24 I told you that you would die in your sins, for unless you believe that I am he you will die in your sins.” 25 So they said to him, “Who are you?” Jesus said to them, “Just what I have been telling you from the beginning. 26 I have much to say about you and much to judge, but he who sent me is true, and I declare to the world what I have heard from him.” 27 They did not understand that he had been speaking to them about the Father. 28 So Jesus said to them, “When you have lifted up the Son of Man, then you will know that I am he, and that I do nothing on my own authority, but speak just as the Father taught me. 29 And he who sent me is with me. He has not left me alone, for I always do the things that are pleasing to him.” 30 As he was saying these things, many believed in him.

Lord Jesus, from whom all good things and all truth proceeds; Grant that by your inspiration, we may think and understand things that are right, and by your merciful guiding may live our lives for you, the Light of the World and the source of Living Waters.
