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” (John 8:12, ESV).
Light is essential to life. Much of our diet hinges on plant life; we mostly eat plants that survive via photosynthesis (using sunlight to create energy) or things that have eaten those plants. Studies have shown that exposure to sunlight is necessary for human health; it is how our bodies produce vitamin D, and sunlight deprivation has been linked to depression. We also rely on light to know where we are and the direction in which we are headed.
Thus, when Jesus called Himself “the light of the world,” His audience knew what He meant. Nobody could misunderstand what He was saying. By calling Himself the light of the world, He called Himself God. At the very least, His hearers recognized that He was claiming to be the Messiah:
“It is too light a thing that you should be my servant
to raise up the tribes of Jacob
and to bring back the preserved of Israel;
I will make you as a light for the nations,
that my salvation may reach to the end of the earth” (Isaiah 49:6).
Natural light allows us to see where we are going. Likewise, spiritual light guides our steps spiritually. Jesus’ audience would have recognized that too:
Your word is a lamp to my feet
and a light to my path (Psalms 119:105).
God’s written Word—the Bible—gives us guidance and direction for our path so that we can know how He wants us to live. Likewise, Jesus is the light of the world and the living Word of God to guide our paths:
In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it…. The true light, which gives light to everyone, was coming into the world. He was in the world, and the world was made through him, yet the world did not know him. He came to his own, and his own people did not receive him. But to all who did receive him, who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.
And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth (John 1:4–5, 9–14).
All of these aspects of Jesus flow together. He is the Word that became flesh to reveal God to us. He is the light of the world, so that we may see. Also, He is life so that we may live. His life is the light of men. His light, His life, and His love guide our steps. We cannot see the path God has prepared for us unless we follow Him.
One of the great lies we deceive ourselves into believing is that we can make it on our own and just call Jesus for backup when things get difficult. We think of Him as our co-pilot (to quote that bumper sticker) when He should be the pilot. We think we can find our way and let Jesus follow us to tweak our efforts. We think we can lead our own lives, yet Jesus tells us that He is the life and that apart from Him we can do nothing (John 14:6; 15:5).
Yet, Jesus is our source of life and light. We need Him first and foremost. But there is another side to this. We do not keep the light to ourselves. We are called to reflect that light to others.
In nature, Earth receives almost all of its light from two sources. During the day, we receive light from our primary source, the sun. However, at night, we receive a little bit of light from the moon. The moon does not create its own light; instead, it reflects light from the sun to us. It takes the light it receives and passes it on to earth.
Likewise, we are called to reflect the light of Jesus:
“You are the light of the world. A city set on a hill cannot be hidden. Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven” (Matthew 5:14–16).
Clearly, we are not the light of the world in the same sense that Jesus is. But, He calls us to take His light and share it with others. We may want to hide it, keeping it to ourselves, but He calls us to spread His light to others. It is through His followers that He is able to shine His light to the nations. When people see us following the true light, they can see the source of all light and life, give glory to Him, and follow Him themselves.
The apostle Paul could tell the churches under his care to be imitators of God (Galatians 5:1) and also imitate him, as he imitated Christ (1 Corinthians 11:1). Can we say the same? Can we tell others that they can imitate Christ by imitating us? Are we reflecting the light, life, and love of God in such a way that people can see the light of Jesus through us?
That is not an impossible idealistic fantasy. That is God’s desire. He wants us to receive His light and reflect it to others. But to do that, we need to first recognize that Jesus is the source of light, life, and love. We cannot create it on our own, but we can reflect His glory as we receive it and follow Him.
