John 3:20 Meaning: Why We Hide from the Light
For everyone who does evil hates the light and doesn’t come to the light, lest his works would be exposed.
For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
For every one that doeth evil hateth the light, and cometh not to the light, lest his works should be reproved.

For every one that does evil hates the light, and does not come to the light that his works may not be shewn as they are;
Meaning in one sentence
This verse explains why people who do wrong avoid the truth: they fear their actions being exposed. Jesus reveals the human heart's resistance to God's light.
Context
Jesus is speaking to Nicodemus, a Pharisee who came to him under cover of night. Their conversation gives us some of the most famous words in the Bible, including John 3:16. In this part of the discussion, Jesus explains why many people reject him. He says that light has come into the world, but people loved the darkness instead, because what they did was evil. Verse 20 gives the reason in more detail: it is not that people stumble into darkness by accident. They choose it. They stay away from the light because they do not want their actions seen. The whole passage shows the difference between those who hide and those who come to the light.
Key Words
The Greek word for evil here is phaula. It originally meant something light, paltry, or worthless, like trinkets that have no value. Then it came to mean morally bad. The verse is not just about terrible crimes; it is about the kind of wrong that is empty and brings no real good to anyone. The verb for ‘does’ or ‘practices’ is prassōn, a present participle. It suggests a pattern, a habit, not a single mistake. This is someone who keeps doing what is worthless. The word for ‘exposed’ is elegchō. In Greek it can mean to convict, refute, or bring to light, often with a sense of shame. But in the Gospel, this exposure is not the final word. The light that reveals is the same light that saves.
How Christians Read This Verse
Reformed commentators like Calvin see this verse as describing the natural human hatred of the gospel. People want to conceal their sins, so they reject the light. Matthew Henry, from a Presbyterian tradition, agrees that sinners hate the light because it disturbs their false peace. The Methodist scholar Adam Clarke notes that the word for evil, phaulos, may come from a Hebrew root meaning ‘to roll in dust or ashes’, a picture of shame and humiliation. Baptist commentator John Gill writes that such people hate Christ and his Gospel because they make evil deeds known. Across traditions, Christians agree: the resistance is not about the light being harsh, but about the heart wanting to stay hidden. All point to the same human tendency to avoid what might call us to change.
A common misunderstanding
Some think this verse describes only non-believers. In fact, the word prassōn (practicing) points to a habitual lifestyle, not a single lapse. Any of us can fall into patterns of hiding. The verse is a mirror for everyone, warning that the instinct to stay in the dark is a danger for every human heart. It invites us to ask: what am I avoiding bringing into the light?
Living This Out
Think about one area of your life you keep in the shadows. It might be a habit you do not want anyone to know about. It could be a resentment you nurse or a truth you keep from someone close to you. You know what it is. Jesus does not mention it to shame you. He mentions it because the light is where healing happens. This week, bring that one thing to him in prayer. You do not have to fix it first. Just let it be seen. The light that exposes is the same light that saves.
Main takeaway: We avoid God’s light when we want to keep our wrong actions hidden, but exposure is the path to freedom.
For Families
For ages 5, 8
When you do something wrong, you might want to hide it. But Jesus is the light. He sees everything and still loves you. You can come to him.
For ages 9, 12
This verse tells us why people sometimes stay away from God. It is because they do not want their wrong actions to be seen. But Jesus did not come to embarrass us; he came to help us change. When you tell him the truth, he forgives you and helps you start fresh. Hiding never works. Coming into the light does.
Questions People Ask
Does this verse mean God hates people who do evil?
No. The verse describes the person's own attitude: they hate the light. God loves the world (John 3:16) and sent Jesus not to condemn but to save. The hatred is on the human side, not God's.
What kind of 'evil' is the Greek word referring to?
The word phaula originally meant 'worthless' or 'trivial,' then came to mean ethically bad or vile. It suggests actions that are empty and of no real value, not just any sin. The verse is about a lifestyle of doing what is shameful.
Why does the verse say 'doesn't come to the light' instead of 'can't come'?
It is a choice, not an inability. The person actively stays away because they do not want their works exposed. Jesus invites everyone to come (Matthew 11:28), but some refuse.
Is being 'exposed' the same as being condemned?
No. The Greek word elegchō means to expose, convict, or bring to light with the aim of correction. It is like a doctor revealing a wound to heal it. John 3:17 makes clear that judgment is not the goal; salvation is.
Does this verse only apply to non-Christians?
The word for 'practicing' (prassōn) describes a habitual pattern. Any Christian can fall into a habit of hiding. The verse warns all of us against the instinct to stay away from God's light when we are doing something wrong.
