Awake, O Sleepers

Ephesians 5:8–14 ESV

8 for at one time you were darkness, but now you are light in the Lord. Walk as children of light 9 (for the fruit of light is found in all that is good and right and true), 10 and try to discern what is pleasing to the Lord. 11 Take no part in the unfruitful works of darkness, but instead expose them. 12 For it is shameful even to speak of the things that they do in secret. 13 But when anything is exposed by the light, it becomes visible, 14 for anything that becomes visible is light. Therefore it says, “Awake, O sleeper, and arise from the dead, and Christ will shine on you.”

Introduction

Lent is a season of awakening—not a gentle awakening, but one that disrupts us when we have grown too comfortable in the darkness.

Paul writes to people who already belong to Christ, yet he urges, “Awake, O sleeper.” This conveys an important message: you can be a member of the church and still be unaware of what Christ is doing. You may believe in the gospel but live as if the light has not fully dawned.

Throughout the book of Ephesians, Paul reminds believers that something transformative has occurred in Christ. Once, they were dead in sin, far from God, and walking in darkness. But now everything has changed: “You were once darkness, but now you are light in the Lord.”

The prophets had foretold this moment. Isaiah proclaimed, “The people who walked in darkness have seen a great light.” In Jesus, that light has arrived.

Thus, Paul’s message is clear and urgent: Wake up. The night is passing, and the light of Christ is already shining. This is why our hope does not disappoint.

Big Idea:

The risen Christ shines on us—so wake up and walk in the light.

1. Once You Were Darkness—Now You Are Light(vs. 8-10)

Paul often reminds believers that a genuine transformation occurs in life when one is in Christ. In Ephesians, he outlines the contrast between our former selves and who we are now. Previously, we were spiritually dead, distant from God, and walking in darkness. However, through Christ, we have been made alive, brought closer to God, and transformed.

This transformation is encapsulated in a powerful statement: 

“You were once darkness, but now you are light in the Lord.” (Ephesians 5:8)

Notice the careful choice of words from Paul. He does not simply say we lived in darkness; he states that we were darkness itself. Darkness was not merely an external environment; it influenced our lives, our thinking, and our desires.

But now, something has changed. Because of Christ, we have become light in the Lord.

This portrayal of salvation is a common theme throughout Scripture. Darkness symbolizes sin, confusion, and separation from God, while light represents life, truth, and salvation. The prophets frequently depicted God’s salvation as the arrival of light. For instance, Isaiah proclaimed: 

“The people who walked in darkness have seen a great light; those who lived in a land of deep darkness—on them light has shined.” (Isaiah 9:2)

Isaiah spoke these words as a promise of the coming Messiah. In Jesus, that promise has been fulfilled; the light has entered the world.

Now, Paul informs the church that this light has transformed us. Those who belong to Christ are no longer characterized by darkness; we are now children of light.

This new identity yields visible results. Paul states that the fruit of the light consists of goodness, righteousness, and truth. When Christ’s light fills our lives, it begins to shape our character. It guides our actions, reveals what is right, and helps us discern what pleases the Lord.

This is why hope does not disappoint.

Gospel Truth:

The light Isaiah promised has already dawned in Christ—and now it shines through the lives of those who follow him.

2. Light Exposes What Darkness Tries to Hide(vs. 11-12)

Paul teaches that living as children of light means refusing to participate in the “fruitless deeds of darkness” (Eph. 5:11). This does not mean withdrawing from the world or avoiding those who live in darkness. Jesus himself entered the homes of sinners and ministered among them. The church is called to remain in the world while refusing to adopt its sinful practices.

Darkness thrives on secrecy. It leads us to believe that if we do not name something, confront it, or bring it into the open, it cannot truly harm us. However, the light of God operates differently. Instead of hiding sin, it reveals it—not to humiliate, but to guide. As the psalmist states, “Your word is a lamp to my feet and a light to my path” (Psalm 119:105). Light does not exist to shame us; it exists to show us where we are and where we are headed.

This exposure of darkness is not only a moral task but also part of a larger spiritual struggle. Later in Ephesians, Paul reminds believers that they wrestle not merely against human opposition, but against “the cosmic powers over this present darkness” (Eph. 6:12). Christ has already triumphed over these powers. Yet they still seek to influence and deceive the world. This means that when believers refuse the works of darkness and bring them into the light, they are participating in a deeper spiritual conflict. Exposing darkness becomes an act of resistance against the forces that seek to keep people trapped in deception.

Throughout Scripture, light naturally reveals what darkness tries to conceal. People often resist the light because it exposes what is hidden within them. Yet believers are called not to accommodate darkness but to shine the light of truth within it. This does not mean condemning the world; rather, it means helping people see clearly and find their way out of darkness.

This is why Lent emphasizes honesty. When Christ exposes what is hidden, he is not withdrawing grace—he is guiding us toward healing. The church shines this light carefully and faithfully so that those walking in darkness may see the path before them.

Gospel Truth:

Hope does not disappoint because the light that reveals is the same light that leads.

3. Awake—Christ’s Light Is Already Shining (vs. 13-14)

Sometimes, light must shine with special clarity to reveal what evil tries to hide. Just as a powerful security light exposes activities hidden in darkness, the light of Christ reveals the schemes of evil that attempt to disguise themselves as good. However, the church must be careful: merely exposing darkness is not enough. If we only denounce what is wrong without highlighting the beauty of God’s truth, we risk drawing more attention to the darkness than to the light. The church must shine the light of Christ in a way that reveals both the falsehood of evil and the greater goodness of God’s kingdom.

This connects directly to the spiritual warfare described earlier. Paul reminds believers that our struggle is not merely against human opposition but against “the cosmic powers over this present darkness” (Eph. 6:12). The forces of darkness rely on secrecy, deception, and confusion. When the church rejects the works of darkness and brings them into the light, it participates in this spiritual struggle. Darkness loses its power when exposed to truth. In this way, shining the light of Christ becomes an act of resistance against the forces that seek to keep the world trapped in deception.

Paul concludes this section with what is likely an early Christian hymn: “Awake, O sleeper, and arise from the dead, and Christ will shine on you” (Eph. 5:14). This is not a warning of doom—it is an invitation to resurrection. It calls us to awaken from the spiritual stupor of sin and step into the life Christ offers.

Paul reminds believers that the decisive moment has already arrived. As he writes elsewhere, “The night is far gone; the day is near” (Romans 13:12). In other words, we should wake up—not because judgment is coming, but because morning has already begun. Christ’s light is not something we wait for at Easter; it is already shining, calling us out of spiritual drowsiness and into renewed life.

When believers awaken to Christ’s light, they step out of the domain of darkness and into the victory Christ has already secured. Their lives begin to shine in ways that expose deception and reveal the truth of God. The battle against darkness is fought not by adopting its methods, but by living openly in the light of Christ.

This is the promise at the heart of the gospel: the light that reveals darkness also brings life.

Gospel Truth:

Hope does not disappoint because the command to wake up is joined to a promise—Christ will shine on you.

Conclusion

Paul’s words present a simple yet urgent invitation: “Awake, O sleeper, and rise from the dead, and Christ will shine on you.” Throughout this passage, Paul emphasizes what the gospel has accomplished and what it calls us to become. Once we were in darkness, but now we are light in the Lord. Because Christ has brought us into this light, we are called to live as children of light, producing the fruit of goodness, righteousness, and truth.

Living in this light means rejecting the works of darkness. Darkness thrives on secrecy, relying on confusion, deception, and silence. In contrast, the light of God operates differently. As the psalmist states, “Your word is a lamp to my feet and a light to my path” (Psalm 119:105). God’s light reveals where we are and where we are headed. It uncovers what is hidden, not to shame us, but to guide us toward healing.

This work of light isn’t solely a personal struggle; it is part of a larger spiritual conflict. Paul reminds us that we wrestle against “the cosmic powers over this present darkness.” The enemy thrives in secrecy and deception. Every time the church upholds truth, rejects the works of darkness, and radiates the light of Christ into the world, we engage in that spiritual struggle.

However, Paul concludes with a promise rather than a warning. “Wake up… and Christ will shine on you.” This is not a call to fear judgment; it is an invitation to resurrection. As Paul writes elsewhere, “The night is far gone, the day is near.” The morning has already begun.

Christ’s light is already shining. So, awaken—not because darkness is prevailing, but because Christ has already triumphed over it. Wake up and live as people of the light. Let the beauty of God’s truth shine through your life.

In Christ, the light has come, and that is why this hope does not disappoint.

Big Idea:

The risen Christ shines on us—so wake up and walk in the light.
