Ephesians 5:16 Commentary: Redeeming the Time

Paul writes to a congregation in Ephesus, the commercial and religious capital of Asia Minor. The city was famous for the temple of Artemis (Diana), one of the seven wonders of the ancient world, and was a hub for magic, trade, and every form of pagan worship (Acts 19). To be a Christian there meant constant exposure to idolatry, sexual immorality, and social pressure to conform. Earlier in the letter Paul has already called believers to “walk as children of light” and to “have no fellowship with the unfruitful works of darkness” (Eph 5:8, 11).

The phrase “the days are evil” likely reaches in two directions at once. First, it points to the moral corruption of the surrounding culture, what Calvin calls “the endless variety of allurements.” Second, it reflects the New Testament’s sense of living in an age that is passing away, caught between Christ’s resurrection and his return. Evil days are not just a problem to endure; they create urgency. Cross-references like Amos 5:13 (“it is an evil time”) and Ecclesiastes 12:1 (“the evil days come”) had already taught God’s people that difficulty concentrates the mind. Paul’s own life, writing from prison, facing frequent shipwreck and opposition, gave weight to his call. To “redeem the time” was not theoretical; it was the daily art of surviving and thriving in a world hostile to faith, using every window of opportunity before it closed.

The consulted sources note no significant textual variants for Ephesians 5:16. The Greek text is stable across the major manuscripts, and the syntax, a present participle depending on the main verb of verse 15, is unambiguous.

Early church writers, including Chrysostom and Augustine, cited this verse to urge Christians to flee the distractions of the theatre and pagan feasts. Monastic tradition read it as the foundation of a disciplined daily schedule, where every hour was assigned to prayer, manual work, or study. The Reformers, Luther and Calvin prominent among them, applied the text to ordinary life: the parent, the merchant, the ruler all “redeem the time” by doing their work faithfully in the world, not by retreating from it. In the Anglophone tradition, Puritans like Richard Baxter meditated on the verse to encourage daily self-examination, and the phrase “redeem the time” found its way into hymns and devotional calendars. Modern application has broadened to include missional urgency, the stewardship of natural resources, and the fight against digital distraction, while remaining centered on the original call: seize the present moment for God before it is lost.

Three-point outline

1. The crisis: the days are evil. The word ponērai (πονηραί) means full of toil, peril, and active moral hostility. Life in a fallen world does not naturally lend itself to godliness.
2. The command: redeem the time. Exagorazomenoi is a commercial picture, buy up the opportunity as you would a rare jewel. The present tense keeps you on the ball; it’s a lifestyle, not a one-off.
3. The wisdom: walk carefully. Verse 15 frames the whole effort: “not as unwise, but as wise.” Redeeming time is the shape wise walking takes when the path is dangerous.

Five-point outline

1. Wake up (v.14). Before you can act, you must be alive to what is at stake.
2. Watch your walk (v.15). Wisdom begins with careful attention to how we live.
3. Buy the opportunity (v.16a). Treat each godly opening as a negotiable asset, secure it before it is gone.
4. Understand the times (v.16b). Evil days are not an excuse to retreat but the very reason to press forward.
5. Be filled with the Spirit (v.18). The engine of all this is not self-effort but the presence and power of Christ through his Spirit.

Illustration hooks

• A friend asks for a favour after a long, draining workday. The clock says there is no time; faith says there is a kairos for kindness.
• A parent has a short window between bedtime and collapse. That half-hour can be given to prayer, a good book, or quiet encouragement for a spouse, or it can be eaten by a screen.
• An unexpected cancellation frees an evening. What looked like a loss is actually a purchased opportunity to connect with someone you have been meaning to see.

Questions your congregation is asking

• How do I tell the difference between being busy and truly redeeming the time?
• What does “evil days” mean for me, living in relative comfort? Does it apply to our age too?
• Is “redeeming the time” guilt about every wasted minute, or is there freedom in it?

We live in a world that constantly pulls us away from what matters. Paul’s short, sharp command to “redeem the time” cuts across our habits of distraction and delay, inviting us to see every moment as an opportunity to be claimed and used for good. Before you begin reading Ephesians 5:15, 20 together, take a moment to share one thing that tends to steal your time and attention this week.

Discussion questions

1. Observation. What two things does Paul command in verses 15, 16? What reason does he give?
2. Observation. Look at verse 15. Why do you think he contrasts the unwise and the wise before he talks about time?
3. Interpretation. The Greek word for “time” here is kairos, not chronos. What difference does it make that the focus is on the opportune moment rather than the clock?
4. Interpretation. What does it mean that the days are “evil”? Does that refer to the moral atmosphere of the first-century world, or to something more permanent?
5. Application. Describe what “redeeming the time” might look like in an ordinary Tuesday, in concrete terms.
6. Application. Is there an “opportunity”, a conversation, a task, a moment of rest, you have been neglecting? What would it cost you to “buy it up” this week?
7. Connection. Verse 18 connects redeeming time to being filled with the Spirit. How does the Spirit enable the kind of watchfulness Paul is calling for?
