Walking in the darkness is something that can cause us serious problems. The darkness prevents us from seeing objects that are around us and that would take us to stumble and even fall and get hit. In addition, in the darkness we lose the sense of direction and that could lead us to the wrong place. Many walk blind and disoriented for life even in daylight. In John 8:12, Jesus tells us that whoever follows Him will never walk in darkness because He is the light of the world and the light of life.
Since its first chapter, the Gospel of John identifies Jesus as the light. John 1:4-5 says: In Him was life, and the life was the light of men. And the light shines in the darkness, and the darkness did not comprehend it. John the Baptist testifies about the glow of light of Jesus, of which says John 1:6-9: There was a man sent from God, whose name was John. This man came for a witness, to bear witness of the Light, that all through him might believe. He was not that Light, but was sent to bear witness of that Light. That was the true Light which gives light to every man coming into the world.
In John 9:5 the concept that Jesus is the light of the world repeats itself: As long as I am in the world, I am the light of the world. Here the Lord emphasizes that He was the light of the world while he was in the world. Does this mean that Jesus is not the light of the world now? No way, because in Matthew 5:14 reveals the mystery: You are the light of the world. A city that is set on a hill cannot be hidden. As disciples and followers of Jesus Christ, we are now called to be the light of the world reflecting the light of life He is.
For us to be the light of the world, we must first receive Him who is the true light. When we reject Him, we miss the opportunity of eternal life and we carry condemnation. In John 3:19-21 we read: And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed. But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.
Jesus is the light and came to take out us from darkness, as Zechariah prophesied in Luke 1:79: To give light to those who sit in darkness and the shadow of death, to guide our feet into the way of peace. And Jesus himself affirms in John 12:46: I have come as a light into the world, that whoever believes in Me should not abide in darkness. Every human being has lived a separate life from God by sin, which has plunged us into darkness. Only the light of Jesus can bring us out of darkness and lead us down the right path to God.
Jesus himself being the way that leads to the Father, He will lead us to God without stumbling. In John 11:9-10 we read: Jesus answered, "Are there not twelve hours in the day? If anyone walks in the day, he does not stumble, because he sees the light of this world. But if one walks in the night, he stumbles, because the light is not in him." Let take advantage of the light, as John 12:35-36 tells us: Then Jesus said to them, "A little while longer the light is with you. Walk while you have the light, lest darkness overtake you; he who walks in darkness does not know where he is going. While you have the light, believe in the light, that you may become sons of light." These things Jesus spoke, and departed, and was hidden from them. God bless you.
