In The Gospel According to Jesus, John MacArthur turns to John 9, the account of the man born blind. He treats it as a key text for his theology of saving faith. In particular, he uses it to support the perseverance of the saints. For this reason, his reading deserves a close look. It shows a pattern that runs throughout the book: importing a theological conclusion into a text that was never built to carry it.
MacArthur’s Two Points
In chapter 6, MacArthur makes two basic moves using John 9.
First, he argues that the man’s early response to Jesus is not yet real, saving faith. This includes defending Jesus before the Pharisees and confessing Him as a prophet. For MacArthur, saving faith only arrives at the end of the chapter. At that point, the man falls before Jesus and worships Him. MacArthur calls this moment “full faith in Christ.” He defines it (p. 81) as “full surrender of the heart, soul, mind, and strength.”
Second, MacArthur argues that salvation is a work of God, so it cannot be deficient (pp. 86, 88). A true work of God will always produce fruit and lasting change in a person’s life. Therefore, he draws a larger thesis from this. The genuine believer will persevere in faith and good works until death. In his view, a believer cannot fall away and die in an unregenerate state.
Put together, MacArthur’s logic runs like this. Faith in Christ is not real faith unless it is full surrender. That surrender includes commitment, obedience, perseverance, and works. And since salvation is God’s work, genuine surrender cannot ultimately fail.
The Problem: The Text Doesn’t Say That
Here the argument runs into trouble. Look at MacArthur’s own reading. Everything admirable the blind man does happens before he is born again. He shows courage before the Pharisees. Over time, he grows in theological clarity. He even accepts expulsion from the synagogue for Jesus’ sake. Only in the final scene, when he worships Jesus, does MacArthur place the moment of regeneration and “full surrender.”
But if that is true, John 9 tells us almost nothing about what happens after that moment. Instead, the chapter simply ends. It gives no account of the man’s later life. It records no ongoing obedience and no endurance through trial. The text simply doesn’t go far enough to show perseverance.
So a natural question follows: how can John 9 establish the Reformed doctrine of the perseverance of the saints, when the chapter never tells us about the man’s life after his conversion?
It can’t. The text holds no data for that conclusion. MacArthur presents it as an exegetical finding. However, on inspection, it is a theological assumption read back into a story that stops short of the question. This is eisegesis: imposing a doctrine on the text rather than drawing it out. MacArthur makes this move again and again throughout The Gospel According to Jesus.
Why This Matters
This isn’t a minor technicality. MacArthur’s larger argument depends on proving two things from Scripture. First, saving faith is inseparable from ongoing obedience. Second, the genuine believer cannot fail to persevere. Moreover, John 9 is his flagship text for that claim. If it lacks the evidence he needs, his argument must stand or fall on other grounds. It cannot lean on this passage.
A careful reading of John 9 simply notes what the text does say. A man receives physical sight. Over several interrogations, he grows in his understanding of who Jesus is. In the end, he worships Him as Lord. The text says nothing about how long that faith lasted over the rest of his life. After all, it was never trying to say it. To read perseverance into that silence makes the text answer a question it was never asked.
A Concluding Thought
Good exegesis lets a passage say what it says. At the same time, it resists the temptation to make it say more. John 9 is a rich story about progressive spiritual sight. A man moves from ignorance, to partial understanding, to worship. It is a wonderful text on how a person comes to faith. But it is not a text about staying in the faith, because it never goes there. Whatever one believes about the perseverance of the saints, that doctrine must find its support—or its refutation—somewhere other than John 9.
