The focus for Jesus’ self-declaration, “I am the light of the world’ is a discussion about his personal testimony about himself and the validity of the claims he makes. This all takes place in John 8, and culminates in Jesus saying, “Before Abraham was born, I am”, which so enraged the Jews with whom he was debating that they picked up stones to stone him. We know from elsewhere in the Gospel that the reason they wanted to stone him was because they believed he was guilty of blasphemy because he was claiming to be God (John 10:33).
In the Old Testament David declares, my God turns my darkness into light, and, The Lord is my light and my salvation (Ps. 18:28, 27:1). Most famously perhaps are the words from Ps.119: Your word is a lamp for my feet, a light for my path.
Isaiah too uses the power of the symbol of light when he speaks prophetically about the coming of a new dawn: The people walking in darkness have seen a great light, on those living in the land of the shadow of death a light has dawned. (9:2). And later when he says: Arise, shine, for you light has come (60:1)
So, light is a powerful symbol of both the presence and the power of God. As John would later write in his first letter: God is light, in him is no darkness at all. (1 Jn.1:5)
Light in John
In John’s gospel, light features 16 times in the first 12 chapters. It is part of John’s opening prologue, it features in the discussion with Nicodemus and is used to describe the ministry of John. It is the self-declaration of Jesus in both chapter 8 and chapter 9 and is used by Jesus himself to talk about his own ministry in chapters 11 and 12.
Incidentally we ought also to remember that Jesus tells his close followers that they too are the light of the world and that Paul would call the Ephesian Christians to live as children of the light (Eph.5:8).
Light reveals God
In his prologue John tells us:
The true light was coming in to the world but would not be recognised. He would give to those who believed in him the right to become children of God. Light and life are linked and the light is more powerful than darkness because the darkness can neither understand nor overcome the light.
This is one of the fundamental things about light. It is light that transforms not darkness. You cannot turn on darkness, you can only turn of light. Darkness is defined by the lack of light not the presence of something more powerful than light. The light that John declared was coming into the world was the life that is expressed in the living Word who is God himself.
Light exposes sin
In his dialogue with Nicodemus, which rather interestingly happens “in darkness” because Nicodemus comes “at night”, Jesus speaks about the power of light to expose. It must have been an interesting discussion as Jesus talked about light and darkness and shadows in the flickering glow of an oil lamp. “Men love darkness,” He said, and the reason they do is because, “their deeds are evil”. The shadows are their natural habitat because the shadows can conceal the true nature of their actions. But light exposes them.
God does not cover up our sin. He exposes it. As Paul puts it: He will bring to light what is hidden in darkness.
Now it has to be said that when you truly think through the implications of that statement, it is far from comfortable. For who really wants their every dark thought and deed exposed to the glaring light of God’s holiness and scrutiny? No wonder we run towards the shadows rather than towards the light. And no wonder it hurts when we come into the light.
But once exposed, it is not God’s intention that we are left to deal with our sin on our own.
Light Liberates
The wonderful thing is that although everything is exposed, nothing is left hidden, the opportunity for freedom also becomes available. Stepping into the light is a choice to live by the truth and not according to a lie. The lie is that we’ll be okay, that somehow God will find a loophole in our favour that will allow us to go on living how we want and at the same time make us acceptable to himself.
Coming into the light is an acknowledgement that we can no longer go on living as if we know best and that our choices have no bearing on our eternal destiny. The light lets us see the real truth that we desperately need God’ forgiveness and grace in order to live in the light. Light sets us free, and when the son sets us free, we are free indeed.
Light offers life
Once we are free, we are free to enjoy a new life. As John would write later:
If we walk in the light, as he is in the light... The blood of Jesus purifies us from all sin.
In his prologue John makes this statement: In him was life and this life was the light of all people.
If you want to know life, then you need to step into the light.
How to walk in the light
I want to offer you two simple guidelines for walking in the light. I’m guessing that we could produce quite a list of things we’d all consider significant, but rather than doing that I want to make it as simple as possible.
Here are my two things. They are taken from Ephesians.
- Walk worthy.
- Imitate God.
To walk worthy is to ask the simple question: Does this honour God? Whatever decision you’re facing, whatever choices you’re about to make, whatever actions you are taking, ask yourself: Does this honour God?
To be an imitator of God is to ask yourself the other simple question: What would Jesus do?
Wearing a bracelet or necklace or carry a key ring with WWJD doesn’t count if you are not asking the question.
Conclusion
Jesus said: I am the light of the world. Whoever follows me will not walk in darkness. He called us to put our trust in the light while we have it. If you choose not to believe, not to trust, then you stay in the darkness. If you will trust Jesus Christ, then you step out of darkness into light,and in the light there is life, there is liberty and there is forgiveness.
So choose: Darkness or light. Which will it be for you?
