How does Satan blind unbelievers?

Question 8051.

Paul says something in 2 Corinthians 4 that explains a great deal of what we see in evangelism. The god of this world has blinded the minds of unbelievers, to keep them from seeing the light of the gospel of the glory of Christ. The enemy works to blind unbelievers, and he is good at it.

If you have ever laid out the gospel clearly to someone intelligent and watched it slide off them, this is part of the explanation. It is not that they could not follow the argument. Something else is in play, and Scripture names it plainly.

The verse that says Satan works to blind unbelievers

2 Corinthians 4:4 reads: “In their case the god of this world has blinded the minds of unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God.” The verb is typhloo, to make blind, and the object is the mind rather than the eyes.

The context is Paul defending his ministry against the charge that his gospel was veiled. His reply is that it is veiled only to those who are perishing, and then he explains why. The problem is not with the message or the messenger but with an active work to blind unbelievers to what is being said.

The god of this world is a title I have written about elsewhere, and it describes influence over the present age rather than ownership of the world. He did not make it and he does not hold it. What he does is exercise real influence within it, and this blinding is one of the main ways he does so.

How the blinding works

Not by force. Nothing in the text suggests the enemy overrides a person’s will or reaches into a mind against its wishes. The methods Scripture describes elsewhere are deception, distraction and the snatching away of the word, and those are quite enough to blind unbelievers effectively.

In the parable of the sower, the seed on the path is taken by the birds, and Jesus explains that the evil one comes and snatches away what has been sown in the heart. Anyone who has spoken to someone deeply moved on Sunday and completely unmoved by Wednesday knows how that looks in practice.

Then there is plain distraction. Keep a person busy, entertained and comfortable and no argument is needed. To blind unbelievers you do not have to disprove the gospel, you only have to ensure it never gets an undistracted hearing. In our culture that is not difficult.

Blindness and responsibility

Here is where I want to be careful. Scripture never uses this verse to excuse anybody. John 3 says people loved the darkness rather than the light because their works were evil, which locates the problem in preference rather than in incapacity. Satan works to blind unbelievers who are already looking away.

Paul says in Romans 1 that what can be known about God is plain to them, and that they suppress the truth in unrighteousness. Suppression is an activity. The blinding is real, and it works with the grain of a will that has already decided, not against it.

So I hold both together without difficulty. There is a genuine enemy at work, and there is genuine human responsibility, and neither cancels the other. That is the consistent pattern of Scripture and it is the pattern I keep to in everything I write about the adversary.

What the blindness is aimed at

Look at the object again: the light of the gospel of the glory of Christ. It is not general religion that is being obscured. People are free to be spiritual, moral, interested in the transcendent, even warm about Jesus as a teacher. The blinding is aimed at one thing.

That is why so much religious sentiment causes the enemy no trouble at all. He does not need to blind unbelievers to spirituality. He needs to keep the glory of the crucified and risen Son out of focus, and a great deal of vaguely religious feeling does that job for him.

It also explains why a clear presentation of Jesus meets resistance that a general talk about values never does. If you have found that conversations go pleasantly until you name the cross, you have located the exact point at which the veil sits.

What lifts it

Paul’s answer is immediate and it is not a technique. “For God, who said, Let light shine out of darkness, has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.” The remedy for blindness is creation light, spoken by God.

That is why he says a few verses earlier that we refuse to practise cunning or tamper with God’s word, but by the open statement of the truth we commend ourselves to everyone’s conscience. Since the problem is a veil, the answer is plain speech and prayer rather than clever packaging.

And it is why we pray for people rather than only arguing with them. If a work is being done to blind unbelievers, then asking God to shine is not a pious afterthought, it is the main event. I have seen minds change after years of prayer and no new arguments at all.

Encouragement for anyone sharing the gospel

Stop measuring yourself by the response. If there is an active work to blind unbelievers, then a lack of immediate fruit does not mean you explained it badly. Paul was the clearest communicator in the early church and he still had to account for people who did not see it.

Keep being clear anyway. The veil is lifted as the truth is stated, not as it is softened. Every instinct in a friendly conversation pulls towards blurring the edges, and that instinct should be resisted gently but firmly.

And remember that you were blind once. Whatever you now see about Jesus, you did not work it out. Someone prayed, someone spoke, and God shone. That memory will keep you patient with people who are exactly where you were, and it will keep you off the high horse that the enemy of souls so easily uses.

Blindness and the natural mind

Paul says something in 1 Corinthians 2 that sits alongside the blinding: the natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned. That is a description of incapacity, and it works together with the enemy’s activity rather than against it. There is a veil from without and an inability from within, and the gospel has to overcome both.

That combination explains something I have watched many times. A person can grasp every fact of the gospel, repeat it accurately, and still see nothing in it. The information is not the problem. What is missing is sight, the moment when the facts stop being data and become glory. Nobody argues themselves into that, and nobody can be shamed into it either. It is given.

Which changes how we speak to people. If the enemy works to blind unbelievers and the natural mind cannot discern spiritual things, then our part is faithfulness and clarity, and God’s part is light. That removes both the pressure to manipulate and the temptation to give up. I have known men and women come to faith decades after the last conversation anyone thought was useful.

Praying for the blind

Since the problem is a veil, prayer is the main work rather than the preliminary. Paul asked the Colossians to pray that God would open to him a door for the word, and he asked the Ephesians to pray that words would be given to him to declare the mystery of the gospel boldly. If anyone could have relied on his own clarity it was Paul, and he asked for prayer instead.

So pray specifically. Ask God to shine into that particular mind, to remove the veil, to give sight rather than mere agreement. Keep a short list and stay with it for years if necessary. The enemy may work to blind unbelievers, and he has never once succeeded against someone God has determined to enlighten, and that is where our confidence in evangelism actually rests.

So, now what?

Pick one person you have been praying for and change what you ask. Instead of asking that they would be more open, ask God to shine into that mind, and keep asking. The problem is a veil, so pray about the veil.

Then keep speaking plainly and kindly, without heat and without spin. You are not responsible for the sight, only for the light. Who has God put in front of you that you have quietly given up on?

“In their case the god of this world has blinded the minds of unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God.”
