The Unfruitful Works Of Darkness (Ephesians 5:11)?

Ephesians 5:11 instructs believers to “take no part in the unfruitful works of darkness, but instead expose them.” This directive is crucial for understanding what it means to “walk as children of light” (Ephesians 5:8). As children of light, we should have nothing to do with darkness. To identify the “unfruitful works of darkness,” we need to explore the immediate context of Ephesians 5:11 and its theological significance.

Ephesians 4—6 is chiefly concerned with the practical application of the gospel. Ephesians 5:1–21 specifically contrasts the conduct suitable for believers with that of their former lifestyles. Paul’s instruction in verse 11, then, exhorts believers to walk in light—that is, in truth and purity—rather than in sin, darkness, and ignorance.

The expression unfruitful works of darkness is rich with meaning. The word unfruitful suggests something that does not produce a positive outcome. The works of darkness do not accord with God’s holy and righteous standard. Regarding spiritual fruit, Jesus says, “You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles? So, every healthy tree bears good fruit, but the diseased tree bears bad fruit” (Matthew 6:16–17). Unfruitful works of darkness are those that come from a diseased and unhealthy root. Sin, immorality, and active rebellion against God are examples of the unfruitful works of darkness. Jesus said that the Father “cuts off every branch in me that bears no fruit” (John 15:2, NIV).

In Scripture, darkness often symbolizes sin, evil, and ignorance. For instance, in John 3:19–20, Jesus says that “people loved the darkness rather than the light because their works were evil. For everyone who does evil hates the light and does not come to the light, lest his works should be exposed” (ESV). The association between darkness and evil aligns with Paul’s message in Romans 13:12: “The night is far gone; the day is at hand. So then let us cast off the works of darkness and put on the armor of light” (see also Ephesians 5:11). The “armor of light” is the virtue that opposes the deeds of darkness, some of which are listed in Romans 13:13. Christ is “the light of the world” (John 8:12, NIV). The armor of light is His gift. He is the one who exposes sin, darkness, and evil.

In the immediate context of Ephesians 5:11, Paul enumerates several behaviors that are characteristic of darkness. The unfruitful works of darkness are such things as sexual immorality, impurity, covetousness, filthiness, foolish talk, and crude joking (verses 3–4, NIV). These things are opposed to the fruitful works of light, which consist of goodness, righteousness, and truth (Ephesians 5:9).

From a theological perspective, the unfruitful works of darkness signify more than morally reprehensible actions; they also represent a fundamental misalignment with the character of Christ. Believers are called to “be imitators of God, as beloved children. And walk in love, as Christ loved us and gave himself up for us, a fragrant offering and sacrifice to God” (Ephesians 5:1–2, NIV). As living and fragrant sacrifices to God, we “take no part in the unfruitful works of darkness”; rather, we expose them (verse 11). In this way, we demonstrate that we are true children of God.

Paul exhorts believers not only to avoid the unfruitful works of darkness but also to bring them to light. This implies a proactive stance against sin, darkness, and evil. Believers should not be silent in the face of sin and immorality; instead, we should lovingly admonish those who are caught in sin, especially our brothers and sisters in Christ: “Brothers, if anyone is caught in any transgression, you who are spiritual should restore him in a spirit of gentleness. Keep watch on yourself, lest you too be tempted” (Galatians 6:1).
