Changing Clothes
What does it actually look like to stop repeating destructive habits and start living a new life?
Ephesians 4:17-5:2
Read the whole passage before anything else. Everything below exists to help you understand what you just read.
17This I say therefore, and testify in the Lord, that you no longer walk as the rest of the Gentiles also walk, in the futility of their mind,
18being darkened in their understanding, alienated from the life of God because of the ignorance that is in them, because of the hardening of their hearts.
19They, having become callous, gave themselves up to lust, to work all uncleanness with greediness.
20But you didn’t learn Christ that way,
21if indeed you heard him and were taught in him, even as truth is in Jesus:
22that you put away, as concerning your former way of life, the old man that grows corrupt after the lusts of deceit,
23and that you be renewed in the spirit of your mind,
24and put on the new man, who in the likeness of God has been created in righteousness and holiness of truth.
25Therefore, putting away falsehood, speak truth each one with his neighbor, for we are members of one another.
26“Be angry, and don’t sin.” Don’t let the sun go down on your wrath,
27and don’t give place to the devil.
28Let him who stole steal no more; but rather let him labor, producing with his hands something that is good, that he may have something to give to him who has need.
29Let no corrupt speech proceed out of your mouth, but only what is good for building others up as the need may be, that it may give grace to those who hear.
30Don’t grieve the Holy Spirit of God, in whom you were sealed for the day of redemption.
31Let all bitterness, wrath, anger, outcry, and slander be put away from you, with all malice.
32And be kind to one another, tender hearted, forgiving each other, just as God also in Christ forgave you.
1Be therefore imitators of God, as beloved children.
2Walk in love, even as Christ also loved us and gave himself up for us, an offering and a sacrifice to God for a sweet-smelling fragrance.
What just happened?
Imagine a city like ancient Ephesus, a bustling port on the Aegean Sea, home to the immense Temple of Artemis, one of the Seven Wonders of the Ancient World. This was a city saturated with pagan rituals, fertility cults, magic, and a pervasive moral permissiveness. Prostitution was common, often linked to religious practices. The societal norm was driven by self-interest, honor, and shame, with little regard for universal ethical standards or the well-being of strangers. The letter writer, Paul, is addressing a group of relatively new believers in this environment, many of whom came directly out of this cultural soup. They had lived their entire lives by its rules, seen its examples, and participated in its practices.
When Paul uses terms like 'Gentiles,' he's not just talking about non-Jews; he's referencing the prevailing culture, the way life was lived outside the specific moral framework that was emerging in the early Christian communities. This culture was characterized by a specific 'mindset' – a way of thinking about the world and one's place in it that Paul saw as fundamentally misdirected. This wasn't about being inherently bad people, but about a system of thought and behavior that was disconnected from what Paul understood as the 'life of God.' Their understanding was 'darkened,' not necessarily malicious, but operating without a certain light.
Paul is writing from a Roman prison, likely in the early 60s AD, to these Ephesians. He's not physically present to guide them day-to-day. So, his letter becomes a substitute, offering practical instructions for how to live as followers of Jesus in a world that largely operates on different principles. He’s already laid out a grand vision of God’s cosmic plan in the first three chapters. Now, he's moving from the 'what God has done' to the 'how we should live because of it.' He’s bridging the gap between profound theological truth and the gritty reality of everyday choices in a challenging cultural context. He's saying, 'Because of who you are now, this is how you should act.'
The Old Wardrobe
Paul starts with a stark warning: "This I say therefore, and testify in the Lord, that you no longer walk as the rest of the Gentiles also walk, in the futility of their mind." The 'walk' here isn't just about physical movement; it's a common biblical metaphor for a person's entire way of life, their conduct, habits, and moral direction. He's telling them to stop living like everyone else around them. He describes this former way of life as operating from a "futility of their mind," meaning a thought process that ultimately leads nowhere productive or meaningful. It's like building a house on sand – a lot of effort for no lasting foundation.
He elaborates on this 'Gentile walk,' explaining it as a state of "being darkened in their understanding, alienated from the life of God because of the ignorance that is in them, because of the hardening of their hearts." This isn't an accusation of stupidity; 'darkened understanding' suggests a lack of clarity, a misapprehension of spiritual reality. 'Alienated from the life of God' doesn't mean God abandoned them, but that their choices and worldview had created a separation. This separation was rooted in 'ignorance' – a lack of knowledge about God's ways – and a 'hardening of their hearts.' This 'hardening' speaks to a stubborn refusal to respond to truth, like a muscle that has become stiff and unresponsive from disuse or injury. It leads to a moral numbness: "They, having become callous, gave themselves up to lust, to work all uncleanness with greediness." 'Callous' here means desensitized, like skin that has thickened and lost its feeling. When people become 'callous,' they lose their moral compass, easily indulging desires ('lust') and engaging in behaviors ('uncleanness') often driven by insatiable cravings ('greediness').
A New Uniform
Then Paul pivots: "But you didn’t learn Christ that way, if indeed you heard him and were taught in him, even as truth is in Jesus." He's reminding them that their new identity in Christ fundamentally changes everything about their 'walk.' They didn't just learn a new set of rules; they 'learned Christ,' implying a personal encounter and transformation. The 'truth is in Jesus' isn't just a philosophical concept; it's embodied in a person, defining reality itself. This truth compels a radical change in behavior, which he describes using a powerful metaphor: "that you put away, as concerning your former way of life, the old man that grows corrupt after the lusts of deceit, and that you be renewed in the spirit of your mind, and put on the new man, who in the likeness of God has been created in righteousness and holiness of truth."
The imagery of 'putting away the old man' and 'putting on the new man' is like changing clothes. You strip off the old, dirty, worn-out garments of your former self – the 'old man' that's decaying because it's based on 'lusts of deceit,' desires that promise satisfaction but ultimately disappoint. And then you 'put on' new clothes, a new identity: the 'new man.' This new self isn't self-made; it's "created in the likeness of God," a mirror image of His character. It's defined by 'righteousness' (right living, right relationship) and 'holiness of truth' (a life set apart, authentic and real). This transformation also involves being 'renewed in the spirit of your mind' – a continuous process of recalibrating one's thoughts, attitudes, and perspectives. It's a mental makeover that aligns with the spiritual change.
Daily Dress Code
Having established the foundational change, Paul then gets into specifics, like a drill sergeant detailing the new uniform's upkeep. "Therefore, putting away falsehood, speak truth each one with his neighbor, for we are members of one another." The logical consequence of shedding the 'old man' is to shed its lies and embrace truth, especially in how we interact. This isn't just a moral imperative; it's practical. As 'members of one another' in the body of Christ, truth fosters unity and trust. He tackles anger: "Be angry, and don’t sin." Anger itself isn't forbidden, but how it's handled is crucial. Don't let it fester ("Don’t let the sun go down on your wrath") or give an opening to destructive forces ("don’t give place to the devil"). This is about managing raw emotion before it contaminates the spirit.
He moves to tangible actions: "Let him who stole steal no more; but rather let him labor, producing with his hands something that is good, that he may have something to give to him who has need." This isn't just about stopping a bad habit, but replacing it with a constructive, generous one. The goal isn't just self-sufficiency but a desire to contribute to others. Then, speech: "Let no corrupt speech proceed out of your mouth, but only what is good for building others up as the need may be, that it may give grace to those who hear." 'Corrupt speech' (sapros in Greek) means rotten or unwholesome, like spoiled fruit. Instead, speech should be constructive, timely, and gracious. He warns against grieving the Holy Spirit (4:30), suggesting our actions and attitudes can deeply affect our connection with God. This section culminates in a comprehensive call to put away bitterness, wrath, anger, outcry, slander, and malice, replacing them with kindness, tenderheartedness, and mutual forgiveness, mirroring God's own forgiveness in Christ. The ultimate goal, he says, is to "be imitators of God, as beloved children" and to "walk in love, even as Christ also loved us and gave himself up for us." This 'walk in love' is the outward manifestation of the 'new man,' exemplified by Christ's self-giving sacrifice.
What are we supposed to see?
This passage shows a God who is deeply committed to the holistic transformation of His people. He doesn't just forgive past mistakes; He invites them into an entirely new way of being. His action isn't just a one-time spiritual transaction, but an ongoing process of renewal – 'being renewed in the spirit of your mind.' This shows a God who cares about how His people think, feel, and behave in the everyday moments, not just their abstract beliefs. He's actively involved in reshaping their character from the inside out, providing a blueprint for ethics that stands in stark contrast to the prevailing culture.
Jesus, as presented here, is not merely a historical figure or a theological concept; He is the living embodiment of truth and the ultimate model for how this transformed life is to be lived. The passage emphasizes that believers 'learned Christ' and that 'truth is in Jesus.' His self-sacrificing love is the standard, the 'sweet-smelling fragrance' that pleases God. This demonstrates Jesus's role not just as a redeemer, but as the active force and perfect example for the 'new man' that believers are called to become. His life, death, and resurrection provide both the means and the pattern for this radical change.
- 1IDENTITY
God creates humanity in His likeness (Genesis 1:26), and through Christ, He recreates us into a 'new man' (Ephesians 4:24) who reflects His righteousness and holiness, restoring our true purpose and belonging as 'beloved children' (Ephesians 5:1).
- 2WHAT HE VALUES
God values truth, sincerity, and authentic relationships within His community, prioritizing behavior that builds others up and honors the Holy Spirit, demonstrating a deep concern for justice, generosity, and grace in daily life.
- 3WHAT HE CONFRONTS
God confronts the 'futility of mind' and 'hardened hearts' that lead to destructive patterns of living, actively opposing falsehood, bitterness, anger, theft, and corrupt speech, because these actions grieve His Spirit and undermine His design for unity and love.
Where this sits in the whole Bible
Ephesians 4:22 → Colossians 3:9-10
Both passages use the imagery of 'putting off the old self' and 'putting on the new self,' emphasizing a complete change in identity and behavior that comes with following Christ.
Ephesians 4:26 → Psalm 4:4
Paul directly quotes from the Old Testament, showing that the idea of experiencing anger without sinning is a consistent biblical principle, not a new concept invented for Christians.
Ephesians 5:2 → John 13:34-35
Both verses underscore that Christ's self-sacrificing love is the ultimate model and defining characteristic for believers, establishing a clear connection between following Jesus and actively loving others.
This passage isn't just a list of dos and don'ts; it's a call to a new way of being, stemming from a renewed identity. It's less about behavioral modification and more about a complete wardrobe change for the soul, driven by an inner transformation.
Don't rush past this
Perhaps the most uncomfortable part of this passage is the blunt assertion that those outside of Christ live in a "futility of their mind" and are "alienated from the life of God." This challenges the modern notion that all paths are equally valid or that good intentions are enough. It suggests a fundamental disconnection from ultimate reality without God, a state of being lost even if one doesn't feel lost. For many, this sounds judgmental and exclusive, directly clashing with a prevailing cultural value of inclusivity at all costs. It's a statement that declares a clear line between two distinct ways of existence.
Another challenging aspect is the absolute demand for radical personal transformation across every area of life – from thoughts (renewed mind) to speech (no corrupt words) to finances (stop stealing, start giving) and emotions (managing anger, no bitterness). It's not a suggestion; it's a command to 'put away' and 'put on.' This can feel overwhelming, suggesting that being a follower of Jesus is not just an additive to one's life, but a complete overhaul, demanding a level of self-control and consistent moral effort that many find daunting or impossible to sustain without constant failure.
Turn it inward
Three questions from this passage. Answer them or just sit with them — nothing here is required to finish the lesson.
God, it's easy to just go through the motions. This passage reminds me that following you means a deep, continuous change, like putting on new clothes every day. Help me to truly shed the old ways of thinking and acting that lead to futility and hurt. Give me the courage and strength to choose kindness, truth, and genuine love, not just for my own sake, but so that I can be a true reflection of your character to those around me. Amen.
This week, identify one specific 'old man' habit or 'corrupt speech' pattern that routinely crops up in your life – perhaps complaining, sarcasm, or gossip. Instead of just trying to stop it, actively replace it. Each time you feel the urge, ask yourself: 'What is the 'new man' way to respond or speak in this situation that would build up and give grace?' Then, try to do that.
History, language, objections and sources. None of it is needed to understand the passage.
Paul describes 'Gentiles' as having a 'futility of their mind' and being 'alienated from the life of God.' Is he saying that everyone who isn't a Christian is inherently ignorant, morally inferior, or beyond God's reach?
Paul is speaking in a specific historical and theological context. When he refers to 'Gentiles,' he's generally speaking about the broader non-Jewish, pagan cultures of his day, which were often characterized by idolatry, various forms of sexual immorality, and self-serving ethics. His language highlights a fundamental difference in worldview and moral source between those living without knowledge of the God of Israel and those who have encountered Christ. He's not necessarily making a blanket statement about the inherent intelligence or individual moral goodness of every single non-Christian person, but rather describing a societal and spiritual trajectory that, from his perspective, leads away from God's intended design. The 'alienation' is a consequence of ignoring or rejecting the 'life of God,' not necessarily an eternal condemnation of every individual. For Paul, the good news of Christ is precisely for those who were 'alienated,' offering a path to reconciliation and renewal.
The passage says, 'Be angry, and don’t sin.' How can anger ever be righteous or non-sinful, especially when elsewhere anger is listed among things to be put away?
This is a common point of confusion. The instruction 'Be angry, and don't sin' is a direct quotation from Psalm 4:4 (in the Septuagint, the Greek Old Testament). It acknowledges that anger, as an emotion, is a natural human response to injustice, wrong, or threats. It's not the emotion itself that is inherently sinful, but rather what we do with that anger. The key lies in the control and direction of the anger. Righteous anger, like Jesus overturning the tables in the temple, is directed at sin and injustice, is under control, and seeks correction or restoration without malice. The passage then immediately adds, 'Don’t let the sun go down on your wrath,' indicating that lingering, uncontrolled anger that turns into 'bitterness, wrath, outcry, and malice' (Ephesians 4:31) is precisely the sinful form that must be 'put away.' So, the distinction is between a fleeting, controlled emotion that can be a catalyst for good, and a corrosive, prolonged state that poisons the soul and relationships. It is the latter that 'grieves the Holy Spirit.'
Paul tells those who stole to 'steal no more; but rather let him labor... that he may have something to give to him who has need.' Is this an unrealistic expectation for someone who might be poor, or is Paul demanding that all Christians become actively philanthropic?
This instruction is not necessarily unrealistic, but it highlights a profound shift in mindset and purpose. For someone who resorted to stealing, whether out of necessity or habit, Paul is demanding a complete reversal of their approach to provision. The new expectation is not just about ceasing a negative behavior (stealing) but actively adopting a positive, productive, and generous one (laboring to give). This isn't about becoming a wealthy philanthropist; it's about changing the fundamental orientation from self-serving acquisition (even through illicit means) to self-sufficient, God-honoring labor that also enables care for others. The goal is to move from being a recipient of ill-gotten gain to a provider who contributes to the common good, particularly for those in genuine need. It reflects a core principle of Christian community: mutual care and responsibility, rooted in productive work rather than exploitation or passive reliance.
The Roman Moral Landscape
To understand Paul's strong language about 'Gentile walk,' it's helpful to grasp the dominant ethical systems in the Roman world. While there were pockets of Stoic and Epicurean philosophy, the everyday morality was often pragmatic, focused on honor, shame, and societal reputation rather than universal ethics or personal virtue in the Christian sense. For instance, sexual ethics were far more fluid; male Roman citizens had significant liberty, and prostitution was legal and common. Lying in business or politics was often accepted if it served one's interests. This context makes Paul's call for radical honesty, sexual purity, and self-sacrificing love even more counter-cultural. He wasn't just suggesting minor adjustments; he was proposing a complete ethical overhaul based on a different source of authority and a different vision of human flourishing. The 'futility of mind' would have resonated with many who felt a lack of ultimate meaning despite material prosperity or philosophical pursuit, a void that the prevailing pagan religions often failed to fill meaningfully.
