The Unfruitful Works of Darkness
Ephesians 5:1-2, 10-11
"Therefore 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...and try to discern what is pleasing to the Lord. Take no part in the unfruitful works of darkness, but instead expose them."
God is our example in forgiveness and in our own walk in love. As beloved children, we aren’t left to figure out godliness on our own, we’re invited to imitate our Father, just as little children naturally mimic their parents in affection, trust, and behavior.
We see God’s character most clearly in Christ’s sacrificial love. Our walk in love mirrors this, forgiving others as we’ve been forgiven. Serving each other selflessly. Prioritizing others’ good. An active costly love that reflects Christ's gospel. And likewise we see that Christ example's discernment which involves thoughtful, Spirit-led reflection.
"Does this action, attitude, or association honor God?"
Then comes the stark contrast:
"Take no part in the unfruitful works of darkness, but instead expose them."
What does it mean to be "unfruitful"?
Literally it means without fruit. It means that something is meant to bear fruit and it isn't. In the biblical worldview, fruit represents positive, life-giving, God-honoring. It's meant to produce growth, blessing, righteousness, eternal value, nourishment for the soul and others.
Take for instance sexual immorality; when twisted outside God's design, it becomes barren (unfruitful). It perverts God’s good gift, and His intent. God created sexuality as a beautiful, fruitful union; meant to produce covenant love, intimacy, children (in marriage), mutual joy, and a reflection of Christ’s love for the church. It may feel intense in the moment, but it leaves emotional wreckage, broken trust, guilt, relational destruction, spiritual disconnection, and often the bad fruit of physical consequences. Unintended pregnancy, disease, divorce, division, dissension and more; so much bad fruit comes from it. And probably worst of all is that it doesn't build up holiness.
Instead, it leads to shame; as Paul notes, "shameful even to speak of." It leads to cycles of addiction, objectification, and spiritual death. It doesn’t just affect one person; it harms others (spouses, children, the church community), spreading impurity, and hardening hearts against God’s truth.
Paul's point is, living in these things is futile; fruitless, pointless, but even worse than that it is destructive to everyone and everything around it. This is why he urges so urgently, "Take no part in them". Don't do it, don't expose others to it, don't talk about it, don't tell jokes about it, don't even think about it. Have no fellowship (do not become partners) with it. Instead expose it. Discern it and expose it.
"Let no one deceive you with empty words" (v. 6a)
By living in the light of truth, speaking truth gently but clearly, and letting Christ’s light reveal their emptiness (fruitlessness) so others can turn to real fruitfulness.
Paul adds to this covetousness, and he drives home its seriousness by calling the covetous person an idolater.
He's essentially listing three categories of the same sin; sexual immorality, impurity, and idolatry. In regard to covetousness, this isn’t just wanting more stuff (greed), it’s an inordinate, consuming desire for what isn’t yours. And by equating these things to idolatry, Paul is viewing these practices as a form of worship. Worshipping the things that consume them, a consuming desire for what God has not given or designed. Basically treating these things as the ultimate source of satisfaction, security, and identity. The person is "consumed" by it, serving it, chasing it, sacrificing for it (time, relationships, integrity, even conscience).
It’s not that one slip up disqualifies; it’s that a life defined by idolatry shows a heart not truly submitted to Christ as Lord and supreme satisfaction. It makes obvious that one is not at all satisfied with Jesus' gospel. Not born again into that covenant relationship. Not honoring God with all his heart, mind, spirit, and strength. He is empty. Fruitless. Self-focused. He's not being generous, not being content, not being holy, not truly submitted to Christ.
The person remains empty because they’ve traded the living God for dead idols, and lacking the marks of regeneration. It’s a diagnostic of the heart. A life habitually characterized by these things.
The unfruitful works of darkness are barren because false worship always is. Premarital sex, adultery, incest, homosexuality, prostitution, bestiality, lust-driven behaviors; in short, "porneia" (sexual immorality) is sex which you should not be having according to God’s standards. It’s not limited to one act but covers the whole spectrum of sexual sin that treats people as objects for gratification rather than bearers of God’s image in covenant love. And the worshiper of these things is left hollow, restless, and alienated from the true Source of life.
This hits hard in our modern culture, where sexual expression is often redefined as personal freedom or identity.
Premarital sex? Come on! It's practically promoted by EVERYONE. In fact you're a fool for not testing driving the car before buying.
Adultery? Its empowering. Living your best life now.
Homosexuality? Oh thats not the same thing! It's not about our loving relationships. No one should tell you who or how to love.
Prostitution? Ahhh, have you not heard of OnlyFans! It's becoming a cottage industry. What they do in private...well okay...so not really private, but...nevermind.
Just about the only things still pretty much frowned upon are incest and bestiality. And those things are making new in-roads into the mainstream marketplace of culturally diverse ideas.
How does this broader biblical picture of porneia resonate with you?
Recognize it in yourself? Completely unrelated to your experience? Not interested in thinking about these things?
When Scripture calls these things "unfruitful works of darkness," it’s not being prudish, it’s diagnosing a profound spiritual and relational barrenness. It’s convicting in the sense that it highlights how seductive the lie is.
"This will satisfy you."
But the gospel counters with:
"Christ is enough."
Satisfaction in Him produces real fruit; contentment, holiness, and generosity. And this is the long and short of it. The unfruitful works of darkness aren’t just moral failings; they’re profoundly barren because they flow from a false worship; premarital sex as "smart testing," adultery as "empowerment," homosexuality as untouchable "love," sex work via platforms like OnlyFans as entrepreneurial freedom (it's just business).
This is where the gospel can shine brightest. It doesn’t shame the struggler; it invites the empty to the feast. It doesn't hide the truth from them, but it invites them to bear fruit that lasts. In Christ, we’re not defined by our failures or cultural lies; we’re beloved children, called to imitate the Father in sacrificial love. Imitation that bears enduring eternal fruit.
