Sermon: Sunday, 25th October, 2026
Speaker: John Johnstone
Scripture: John 9
People make claims all the time without being able to back them up. Politicians claim they will reduce NHS waiting times, create more jobs and build more homes and put the ‘great’ into Britain again. Sometimes they make some progress. Often, they do not. When the claims are tested, they don’t always stand up. Banks and other businesses claim to put the customer first; however, when things go wrong, do they always put you first? Friends might claim to be there for you, no matter what. Are they there when we need them? Sadly, not always. What I love about Jesus is that the claim he makes is greater than all of these claims put together. It almost sounds too good to be true. But then he backs up the claim with evidence and reality. In John 9:5, Jesus claims to be the ‘light of the world’. Let’s consider this claim and whether or not it stands up to being tested.
1. Jesus’ claim
In what sense is Jesus the light of the world? Light reveals things to us. Imagine you’re in a dark place and feel disorientated, but then you turn on the light and you can see how things really are. Jesus makes God known to us. He shows us who God is and what God is like, because he is God. ‘No one has ever seen God, but the one and only Son, who is himself God and is in the closest relationship with the Father, has made him known.’ (John 1:18)
Light is needed to bring life to living things. Jesus, and only Jesus, can give you eternal life in Heaven. ‘In him was life, and that life was the light of all mankind.’ (John 1:4) In the Bible, light speaks of coming out of the darkness of a broken relationship with God and being saved so we can have true friendship with God. ‘I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.’ (John 8:12)
Finally, light also speaks about judgment. Why? Because light reveals what is really there; it exposes the difference between those who receive Christ and those who reject him. If you shine a light into a messy cupboard, it exposes the dirt and the mess and so can be uncomfortable. We might rather turn the light off again and ignore what the light reveals. ‘This is the verdict: light has come into the world, but people loved darkness instead of light because their deeds were evil. Everyone who does evil hates the light, and will not come into the light for fear that their deeds will be exposed. But whoever lives by the truth comes into the light, so that it may be seen plainly that what they have done has been done in the sight of God.’ (John 3:19-21)
Astonishing! Jesus claims to be able to reveal to us exactly what God is like (because he is God), and that through him we can be true friends with God and live forever. He also claims that he will expose the uncomfortable and horrible things in our lives, like pride and selfishness and godlessness. The question is, will Jesus’ claim stand up? Yes! In verse 1, we meet a man born blind and by verse 6 we are told that he comes home seeing. This miracle is a sign, given by Jesus, proving that he is the light of the world. The man who had never seen a sunrise or a flower or a new-born baby can now see everything. And even better, by the end, he sees who Jesus truly is. He receives spiritual sight. In this chapter, a blind man comes to see who Jesus really is and comes to trust him; and those Pharisees who think they can see are shown to be spiritually blind.
2. The miracle itself
This account starts off with the ignorance of Jesus’ disciples. They see this congenitally blind man and make a seriously wrong assumption- they assume that the reason he is blind is because he has sinned in the womb or because his parents had sinned. This is a hugely damaging and false assumption. The man is not blind because of his own sin or that of his parents. And yet when the disciples look at him, rather than helping him, they are judgmental as well as being plain wrong. In effect, they think he deserves to be blind. Jesus knows all things and so he knows that his blindness is not connected to a particular sin, but will result in a something wonderful- people will see the greatness of God as he is healed.
Is the relevant for us today? Yes! People make all kinds of false assumptions about suffering all the time. Job’s friends wrongly assumed he deserved his suffering. You might look at your own suffering and think, ‘God is punishing me for something.’ Do you really know that? Of course not!
God gives us no easy explanations about our suffering. Hindus want to explain it with karma- as if our suffering now is a result of evil in a previous life. This too is false. The truth is most of the time we are not told why certain things have happened to us. It is not explained. What we can say is that for God’s people all suffering has a good reason, and is an opportunity to trust in God. But we are not given facile answers to the specific reasons. So, don’t be quick to condemn others or yourself when things go wrong, unless there is an obvious link between your sin and suffering. We are not given big explanations by God about the details of our lives, however much we may want that. Instead, Jesus focuses on what God can do in in our current situation. That is what matters. We must trust that there is a divine purpose in all our suffering, even though it is usually hidden from our view.
Notice that the blind man does not call out to Jesus for help. Nonetheless, Jesus takes the initiative and goes to help him and heal him. It is striking that Jesus makes mud with his saliva and the dust of the ground and covers the man’s eyes and then commands him to wash in Pool of Siloam. Jesus instructed him to believe and to act on that belief. It was when the blind man ‘went and washed’ that he came back seeing. This is the message that Jesus has proclaimed all through John’s Gospel: that we must believe in order to be saved. If you trust in the commands and promises of Jesus, all will be well. In his obedience to Jesus’ instruction, we see the man’s faith. He takes Jesus at his word.
On the first day of Creation, God said, ‘Let there be light’ and there was light. On the sixth day of Creation, God made man. What material does he use? The dust of the ground. Here, in John 9, we find Jesus bringing both physical and spiritual light to a blind man. How does he do it? He uses the dust of the ground to create sight.
Who do you think Jesus is? Surely, giving sight to the blind is something that God alone does. ‘The Lord sets prisoners free, the Lord gives sight to the blind…’ (Psalm 146:7-8)
Isaiah gives a prophecy about what will happen when the true Saviour comes: ‘In that day the deaf will hear the words of the scroll, and out of gloom and darkness the eyes of the blind will see.’ (Isaiah 29:18)
‘Then will the eyes of the blind be opened and the ears of the deaf unstopped.’ (Isaiah 35:5) I love the man’s reasoning: ‘Nobody has ever heard of opening the eyes of a man born blind. If this man were not from God, he could do nothing.’  : (John 9:32-33) This miracle is a sign pointing to who Jesus is. He is God who has come to earth to save us. He is the light of the world.
3. From spiritual blindness to sight
What is Jesus saying to us through this sign? All human beings are like the blind man without Jesus, who is the light of the world. We do not know and cannot see the true meaning of life. This means we are living in spiritual blindness. We do not know the correct way to Heaven, and we do not give God his rightful place in our lives. We are still in our sins and need God’s forgiveness. We can no more save ourselves, than the blind man could heal himself of his own blindness. We need the initiative of Jesus. The good news is, Jesus comes to us too and freely offers us forgiveness and new life, if we believe in his promises to us.
As we read of this blind man gaining his sight, this is a spiritual picture of becoming a Christian. Because we know Jesus as our King and Saviour, we now understand the true purpose of our lives- to bring glory to God and enjoy God’s goodness. We can now see who Jesus really is, the Creator and Messiah and the Son of Man. And we trust in him and through his death and resurrection are guaranteed to have new life in Heaven.
I love the way that the blind man gradually begins to see more and more of who Jesus really is. In verse 11, Jesus is just ‘the man called Jesus’. In verse 17, Jesus is a prophet. In verse 25, we read: ‘One thing I do know, that though I was blind, now I see.’ Jesus the miracle-worker. In verses 33 the man concludes that Jesus must be from God. The climax comes in verse 38, where he believes and worships Jesus.
Let me ask you the same question that Jesus asks in verse 35: ‘Do you believe in the Son of Man?’ This is the most important question in all the world. In other words, do you believe that Jesus is truly the light of the world? Do you believe that he is the source of spiritual life and light and truth? And if so, are you following Jesus? He promises that those who follow him shall never walk in darkness but have the light of life.
Jesus’ claim forces you to make a decision about him. Will you recognise your spiritual blindness and come to him for light, or will you reject Jesus and remain in darkness? Jesus does not come to you and ask, ‘Do you understand all the suffering in the world?’ or ‘Do you understand the justice of God entirely?’ or ‘Can you explain why God has planned things out the way he has?’ These questions are beyond us. They are not revealed. God does not ask us such questions. But he does ask you this: ‘Do you believe in the Son of Man? Do you believe he died for you?
4. A sad reality
‘Jesus said, ‘For judgment I have come into this world, so that the blind will see and those who see will become blind.’ (John 9:39) When someone loves darkness, the very light that could help them may become something they resist or flee from.
Picture a room in which someone is secretly stealing from a cupboard. As long as the room remains dark, he can continue without being noticed. Suddenly, someone switches on the light. The light has not committed an offence against him. It has simply revealed what he was doing. He might complain about the brightness, blame the person who switched it on, or demand that the light be turned off. But none of those reactions changes what the light has revealed.
Richard Phillips: ‘Why would the Pharisees so stubbornly reject Jesus, despite his saving power? The reason is that they did not want the kind of Saviour he was. They resented what it implied about them. They wanted to be affirmed by God on their own merits, not forgiven through a Saviour.’
People object to Jesus today for the same reason. They object to confessing their sin before God and admitting their need for the kind of Saviour Jesus is, the Lamb of God who died for our sins’ (John 1:29). Christ’s light reveals the pride and perversity of the human heart. Jesus is confronting people who claim to see while refusing to acknowledge their blindness’.
We see the blindness of the Pharisees in the way they twist and distort the Sabbath day, making it a burden instead of the blessing it is meant to be. We see their blindness in their lack of joy at the miraculous healing which they know full well has taken place. Rather than considering the evidence and what it reveals about Jesus, they focus on Jesus’ breaking their man-made and distorted rules, then they insult the man born blind, before eventually casting him out. They are the opposite to Jesus. Jesus promises that all who come to him in faith will never be cast out. They think they see better than everyone else, but in fact they are blind. Tragically, they reject Jesus, the light of the world.
Let’s end with the wonderful testimony of the man born blind. He cannot answer every question, and he does not initially understand everything about Jesus. But he knows what has happened to him. ‘Though I was blind, now I see.’ (John 9:25)
Jesus reveals more to him and we read: ‘Then the man said, ‘Lord, I believe,’ and he worshipped him.’ (John 9:38) This is what true spiritual sight is: worshipping Jesus.
