“Jesus answered, “The light will be with you only a little longer. Walk while you have the light so that darkness doesn’t overtake you.” (John 12:35 HCSB)
Jesus tells the crowd teeming in Jerusalem at the Feast of Passover to “walk while you have the light so that darkness doesn’t overtake you.” From which we can conclude a couple of obvious things:
- It is possible to be overtaken by darkness
- Walking in the light prevents the darkness from overtaking us.
What is the light? I’m glad you
didn’t asked. John has already told us the answer to that question:
“Life was in Him, and that life was the light of men. That light shines in the darkness, yet the darkness did not overcome it.” (John 1:4–5 HCSB)
In this case the correct answer is indeed: Jesus. Jesus had life in him, and that life was the light of men. If that isn’t clear enough [yes, John understood Marines quite well, I think] then we have Jesus himself:
“Then Jesus spoke to them again: “I am the light of the world. Anyone who follows Me will never walk in the darkness but will have the light of life.”” (John 8:12 HCSB)
So in John 12.35, Jesus is merely telling the crowds what he had already told them before. He says: walk in the light, because that is the way that you will be delivered from darkness. Oh, by the way, I am the light of the world.
What is the darkness? Evil, immorality, everything that opposes God. As John will put it later: “Now this is the message we have heard from Him and declare to you: God is light, and there is absolutely no darkness in Him.” (1 John 1:5 HCSB).
Darkness is the absence of God.
Micah Wilder does a pretty good job explaining what it looks like to be in darkness and then come to know the light of the world.
