From Darkness to Light: Waking Up in Ephesians 5

Some days you reach the evening without knowing quite how the day went. You did what you had to do, answered messages, saw things, heard things. But if someone asked, "What mattered today?", the answer would be slow to come.

This is not a crime or a flaw of character. It is what happens to almost everyone when life runs on autopilot. There is an old image for it: sleeping with your eyes open. The Bible speaks of it in a short, beautiful letter, and the way out it points to is not a technique. It is a light.

Sleeping without noticing

A sleeping person does not choose to stop noticing the world. They simply stop. Waking life can be like that too: habit takes over, hurry decides for us, and the big questions (where am I going? what do I love?) wait for "when there is time."

Today, a lot pulls at our attention without asking permission. How that happens is the subject of other essays in this series. Here the question is older and simpler: what does it mean to wake up, and who wakes us?

A letter to people who had already changed places

The main passage is Ephesians 5:8–14. A little context helps first.

The letter to the Ephesians comes from the Christian tradition that attributes it to the apostle Paul, who writes it from prison. Some scholars debate whether he wrote it himself; the Brotherhood does not settle that question here, and the meaning of the passage does not depend on it. It is also debated who the first readers were: some early manuscripts lack the words "in Ephesus," so many think it was a letter meant for several communities in the region.

What matters is the tone. Chapters 1 to 3 speak of what God has already done in Christ. Chapters 4 to 6 say how to live from that. In other words, the invitation to live differently comes after good news, not before it.

Wake up, sleeper

What the text says. Paul writes to his readers: you were once darkness, but now you are light in the Lord. So live as children of light. He says the fruit of light is goodness, righteousness and truth, and asks them to find out what pleases the Lord. He also speaks of the "works of darkness," which bear no fruit: he asks them to take no part in them and to bring them into the light instead of leaving them hidden. At the end, with "this is why it is said," he introduces a short line that sounds like verse: "Wake up, sleeper, rise from the dead, and Christ will shine on you."

What it means. First, notice two small words: "were" and "are." Paul does not say "try to become light." He says that, in Christ, they have already moved from darkness to light. The request to live as children of light follows from a change that has already happened.

Second, the closing line. Many scholars think it is a quotation, perhaps from a hymn or a prayer used in the first Christian communities, possibly at baptism. That is a hypothesis; the text does not say where the line comes from, and some hear in it echoes of Isaiah, who calls the dead to wake (Isaiah 26:19) and announces a light that dawns on the people (Isaiah 60:1). The central meaning, though, is clear. Sleep and death are pictures of a life without God, without direction, closed in on itself. To wake is to leave that life. And who turns on the light? "Christ will shine on you." The light is not won by the one who wakes. It comes from outside, like the sun coming through a window.

Third, the verb in verse 10, which translations render "find out," "discern" or "test." The children of light are not handed a finished list; little by little they learn what pleases God. That fits the way Jesus taught: invitation and path, not pressure.

What changes in life. This part is application, not something Paul said in these words. If the light comes from Christ, the first step for someone who feels on autopilot is not a rigid plan. It is to look toward the light: pray, read a scene from the Gospels, spend some time in silence before God. The rest comes later, slowly. Someone waking in the morning does not conquer the day; they open their eyes and let the light in.

Light that shows, not light that accuses

Verses 11 to 13 often sound frightening. They speak of "exposing" the works of darkness, which can feel like being caught in a spotlight. It is worth reading them slowly.

The Greek word in verse 11 (elenchō) can be translated "expose," "show," or "rebuke," and translations differ. So the exact idea of the verse is debated. Verse 13 gives a clue that light, above all, lets us see: everything the light touches becomes visible. Light does not create the problem; it shows what was already there. The end of the verse is difficult in Greek. It may mean that light is what makes things visible, or that whatever is brought into the light becomes light. On the second reading, showing is already the start of healing.

This connects with another saying of Jesus, in the Gospel of John: whoever does the truth comes to the light (John 3:21). The verse before uses the same Greek verb: whoever does evil avoids the light so that their deeds will not be exposed (John 3:20). Coming to the light is the act of someone who no longer wants to live hidden, not of someone afraid of punishment. In the parable of the son who returns home (Luke 15), the son begins to change only when he "comes to himself." And the father runs to meet him before hearing a word, and does not even let him finish the speech he had prepared. In Scripture, the light of Christ wants to heal what it shows.

This does not remove the seriousness of the subject. The text speaks of things that bear no fruit and of things that are shameful. But the direction of movement is always the same: from shadow to light, not from light to punishment.

Waking up together

There is another detail that is easy to miss. Paul writes in the plural. The letter's readers are a community, and right after this passage he speaks of singing together, giving thanks together and submitting to one another (Ephesians 5:19–21). Another of his letters says something similar: "you are all children of the light, children of the day" (1 Thessalonians 5:5), and the advice that follows is to encourage and build one another up.

Waking is usually easier with someone beside you. When a friend asks, "How are you, really?", the question is already a small light. When a community gathers to read, pray and talk about what matters, it creates a space where staying awake takes no heroic effort. Meeting in person plays a role that no screen replaces.

Honest questions

I do not feel like a child of the light. Does this not apply to me? The text does not depend on how a person feels on a bad day. It speaks of an identity given by Christ, and the invitation is to live in line with it, little by little. Feeling far away is a good reason to look toward the light, not to give up.

Does this mean people who are not Christian live in darkness? Paul describes life far from God as darkness, but he begins with his readers' own story: "you were." He does not speak from above; those who received the letter had been in the same place (Ephesians 2:1–5). The image is not a label for judging people: the light comes from Christ as a gift, not as a prize for those who think they are better. Jesus received seekers with respect, like Nicodemus, who came at night with questions (John 3:1–2). The Brotherhood speaks to anyone who wants to seek, without hurry and without pressure.

Is waking up a single moment or a path? The text uses an image of a moment ("wake up"), but the rest of the letter describes a whole life of growing. Christian traditions differ on how much to stress the moment and how much the process. The honest answer is that both appear in Scripture.

One small step

Instead of a list of changes, a simple question: where this week do you feel you are sleeping with your eyes open? It might be a routine, a conversation you keep postponing, a question that always waits for later.

One possible step: set aside ten minutes, without a screen, to read Ephesians 5:8–14 slowly and tell God, in your own words, what the light is showing you. If there is someone you trust, tell them too. Nothing has to be solved today. Opening your eyes is already a beginning.
