The Constant Dance of Travel Roommates personal story · unit #40 — Develops the travel roommate illustration in detail, describing the constant negotiations and attentiveness required when sharing space with someone, setting up the analogy that believers are always in such a relationship with the Holy Spirit.
Theological claims· 15
  1. The original audiences possessed cultural and theological contexts that made the two-self concept immediately intelligible without requiring the kind of explanation modern readers need. unit #4
  2. Modern Christians suffer a discipleship deficit compared to the early church because they lack both Old Testament familiarity and early explicit teaching on the two-self concept that was standard in apostolic Christianity. unit #9
  3. Christians are genuinely two selves—an old self and a new self—and this is not metaphorical language but the actual structure of Christian identity established through God's transformative work. unit #12
  4. Complete freedom from the old-self struggle is impossible in this life; all biblical commands to put off and put on exist precisely because this tension is constant until glorification. unit #16
  5. Christians must constantly and actively choose which self they will inhabit because defaulting to passivity means defaulting to the old self. unit #17
  6. God's explicit plan for Christian transformation is fundamentally imitation of Jesus Christ. unit #20
  7. Christ himself is the curriculum of Christian transformation, not merely principles or virtues derived from him, and knowing him personally is the essence of spiritual life. unit #22
  8. Modern individualism is a deceptive form of worldly imitation that masks its conformity by claiming authenticity, making it functionally cult-like in its denial of imitative influence. unit #24
  9. Christianity's unashamed call to imitate Christ is morally superior to worldly systems that hide their imitative demands, and Christ is objectively the worthiest possible object of human imitation. unit #25
  10. Most recurring sin patterns result not from insufficient spiritual devotion but from disordered life systems that structurally promote failure, requiring practical redesign with help from the church community. unit #30
  11. Christians wrongly over-rely on mystical intervention while neglecting the structural life-ordering that God expects them to undertake using ordinary wisdom. unit #32
  12. Christian transformation depends on building systems that structurally promote godliness rather than merely setting spiritual goals, because people default to the level of their systems, not their aspirations. unit #33
  13. Systems must be designed to protect your weakest, most vulnerable self, not your strongest, most motivated self, because the latter builds systems the former cannot maintain. unit #34
  14. Acedia deceives by making God feel distant during temptation, but remembering the constant indwelling presence of the Holy Spirit is the biblical antidote to sins of indulgence. unit #38
  15. All Christian behavior flows downstream from Christ's incarnation and atoning death, and the Lord's Table functions as a deliberate system to structurally anchor believers in this reality. unit #44

0 · Frames the sermon as the second installment in a series on personal transformation, orienting listeners to the ongoing exploration and encouraging them to catch up on prior teaching if needed

We're in Ephesians, again this morning, Ephesians chapter 4. We're in part 2 of a little series, little mini-series we're engaged in over the last week and this week! Related to this question of personal transformation. How do we make change in our lives? And if you didn't hear last week's message, I would encourage you to revisit that.

1 · Provides the full biblical text for the sermon, reading Ephesians 4:17-24 to establish the scriptural foundation for the teaching on transformation and the two-self framework

Let me read starting in verse 17. We'll pick up mostly in verse 20, but let me give us some context here in Ephesians chapter 4, starting in verse 17. Now this I say and testify in the Lord, that you must no longer walk as the Gentiles do in the futility of their minds. They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them due to the hardness of their hearts. They have become callous and given themselves up to sensuality, greedy to practice every kind of impurity. But that is not the way you learned Christ. Assuming that you have heard about him and were taught in him, as the truth is in Jesus, to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your minds and to put on the new self created after the likeness of God in true righteousness and holiness.

2 · Signals the structural organization of the sermon into three main tools or insights, preparing listeners for the framework that will govern the teaching

Well, we are going to continue building this toolkit for personal transformation again this week with three additional insights into how the Bible talks about transformation.

3 · Introduces the theological concept of dual selfhood as it appears pervasively across New Testament writings, noting that the apostles assume audience familiarity with this framework rather than explaining it from scratch

Now the first thing I want to discuss is this thing we'll see throughout the scriptures, and that is some kind of a reference to two selves. You'll see this a lot, and one of the most interesting things, and I'll tell you about my thought journey on this particular aspect, but you'll see in almost every apostle that writes something in the New Testament, you'll see a reference to an old self and a new self, an old man and a new man, a flesh and a spirit, and it's all presented to you as if you already know what that's about. There's really almost no teaching on the concept itself. It simply employs this kind of language that we see here. Put off your old self, which belongs to your former manner of life, and put on your new self, as if the original audience knew what this entailed.

4 · Poses the interpretive question of why the two-self concept appears without explanation and sets up the argument that the original audiences possessed cultural and theological frameworks modern readers lack

Now let me give you some reasons why I think that's happening. Why it is is that the original audiences didn't need the explanation that maybe we do to understand what is he talking about here? First of all, don't miss, I just said, this stuff appears in different ways in most of the New Testament sections on ethics. New self, old self, spirit, flesh, new man, old man. It's all the same discussion, but why is it that it's always presented as if the audience knew what was happening?

5 · Begins tracing the biblical-theological roots of the two-self concept by pointing to Old Testament patterns of name change as identity transformation, establishing precedent for the New Testament teaching

Well, let me give you a couple of tracks to think about. First of all, you know, there is just an Old Testament pattern that these believers would be more familiar with than us, and I would pick that pattern up with the naming that happens in the book of Genesis.

Recent preaching context

The three sermons immediately preceding this one in the preaching schedule.

Feb 1, 2026
Paul prays that Christ would dwell richly in the Ephesians' hearts because walking worthy of our calling — living as fully integrated people who love God with heart, mind, body, and soul — requires the indwelling love of Christ as the commanding center of our being.
Ephesians 3:1-21
Feb 22, 2026
All growth — numerical, relational, or theological — is only good if it is growth in Christ, who must be the substance, standard, source, and goal of everything the church is and does.
Ephesians 4:11-16
Mar 1, 2026
Because God has given us a new nature in Christ and is working in us, we must work out our salvation by beholding Christ, praying for heart transformation, and making structural life changes that enable obedience — understanding that sanctification, unlike salvation, requires our conscious participation with God.

Small-group discussion

6 questions for your group this week

  1. Chris described the 'dual identity' of the Christian as possessing both an old self and a new self. What does Paul mean when he tells us to 'put off your old self' and 'put on the new self' in Ephesians 4:22-24, and why does he frame this as something we must actively do rather than something that happens to us automatically?
    Ephesians 4:22-24
    → Can you think of a recent moment when you felt the tension between these two selves—when old patterns pulled at you even though you belong to Christ?
  2. The sermon emphasizes that Christ himself is the 'curriculum' of our transformation, not just a moral example or a source of principles. What does it mean practically to imitate Jesus Christ as your complete pattern for life, and how is that different from simply trying to live by Christian principles?
    Ephesians 4:20-21
  3. Paul lists concrete behaviors in Ephesians 4:25-32—telling the truth, working with our hands, guarding our speech, managing anger. Why do you think the sermon argues that these specific, 'ordinary' commands are just as important to sanctification as more overtly spiritual practices like prayer or Bible study?
    Ephesians 4:25-32
  4. Chris claimed that most recurring sin patterns don't result from insufficient spiritual devotion but from 'disordered life systems that structurally promote failure.' What does it look like to 'engineer' your life—to build practical systems—that make sin less likely and obedience more natural?
    → Can you name one area where your current life structure actually works against the godliness you're pursuing, and what would need to change?
  5. The sermon surfaces a fallen condition focus: we often mistake passivity for spirituality, waiting for God to transform us while neglecting the active choice to inhabit our new self. How does the gospel address this tendency—what has Christ accomplished that both humbles our self-effort and empowers our active cooperation in transformation?
    Galatians 5:16-17
  6. Paul concludes Ephesians 4:32 by calling us to forgive 'as God in Christ forgave you.' How does remembering what Christ has done for you in his incarnation and atoning death become a practical tool—a 'system'—for reshaping how you treat others this week?
    Ephesians 4:32

Daily readings · Monday–Friday

5-day reading plan

This week we walk through the three tools of Christian transformation: understanding our dual identity, imitating Christ as our complete pattern, and engineering practical systems that structurally promote obedience.

Monday Galatians 5:16-17

Paul writes that the Spirit and flesh war against each other, and we cannot do what we wish—this is the lived reality of the two-self structure Christ creates in us. This passage confirms that the tension between old and new self is not a sign of spiritual failure but the actual condition of sanctification in this life. We are not meant to expect complete victory over the old self now, but rather to recognize and actively choose the new self we've become in Christ.

Tuesday Colossians 1:15

Paul calls Jesus the image of the invisible God—the exact representation of divine glory and character. When we study Christ, we are not extracting ethical principles; we are beholding the person who is himself our transformation. To know Christ personally is to have the curriculum of sanctification, because growing into his likeness means learning to see what he sees, value what he values, and love what he loves.

Wednesday Philippians 2:6-8

Christ emptied himself, humbled himself, and obeyed to the point of death—this is the pattern we are called to follow, not a burden imposed by external authority but the demonstration of true greatness. Our culture whispers that authenticity means rejecting imitation, but Christ shows us that the greatest dignity lies in voluntary, glad submission to the Father's will. We imitate not a hollow ideal but a person whose obedience purchased our redemption.

Thursday Proverbs 30:8-9

The wise person asks for neither poverty nor riches but daily bread—a prayer that reveals how life conditions shape spiritual stability. We default to the systems we build, not to our finest aspirations; the person who structures their life toward financial dependence on God is already half-protected against the pride that wealth tempts. Our practical decisions about money, time, relationships, and environment are not secondary to spiritual devotion but are the very means by which grace takes root in our daily lives.

Friday 1 Corinthians 6:19

Paul reminds us that our bodies are temples of the Holy Spirit, purchased by Christ's blood—this theological ground transforms how we order our lives. When we engineer our systems (our schedules, our environments, our community practices), we are not striving to earn favor but responding to the grace already accomplished. The structural discipline we undertake is the grateful, embodied response of those who have been redeemed, not the anxious effort of those still trying to win God's approval.

Pray together this week

Prayer for the Dual Self and Structured Obedience

Father, we come before you in awe of your transformative grace. You have made us new creatures in Christ, born again with a new self created in your image and likeness (Ephesians 4:24). Yet we confess that we live in the constant tension between two selves—pulled toward old patterns of worldly thinking even as your Spirit dwells within us (Galatians 5:16-17). We acknowledge our weakness: we default toward passivity and assume that spiritual aspiration alone will carry us forward, when in truth our lives reveal what our systems actually demand of us.

We thank you that in the gospel we are not left to wage this battle through willpower alone. Christ himself is our complete pattern, our standard, and our curriculum for transformation. He humbled himself in incarnation and purchased our freedom through his atoning death (Philippians 2:6-8). Through his Spirit's indwelling presence, we are never abandoned to acedia's deception—you are constantly with us, closer than our next breath (1 Corinthians 6:19).

We ask you now to grant us wisdom and courage to engineer our lives toward obedience. Give us insight to see where our current systems structurally promote failure, and grant us the humility to redesign them—not according to our strongest aspirations but according to our weakest moments. Help us to involve our brothers and sisters in this work, building accountability and mutual encouragement into the very architecture of our days. Guard us from the modern deception that masquerades as authenticity while hiding its conformity to worldly patterns. Instead, compel us to glory in our imitation of Jesus Christ, who alone is worthy of our complete allegiance.

Treasure us with grace to choose the new self today, and every day until we see you face to face. To you be all glory in the transformation of your people.

Which Self Are You Wearing Today?

For the parent

Chris talked about how every Christian has two selves living inside—an old self that wants worldly patterns, and a new self created in God's likeness. This prompt invites your family to name specific moments when they felt the tension between these two selves, making the abstract concept concrete and personal. Listen for honesty about struggle; the goal is to normalize the daily choice between old and new patterns.

Chris said we all have an old self and a new self fighting for control. Can you think of a time today—or this week—when you felt that fight happening inside you? Maybe you wanted to do something mean, or selfish, or lazy, but you felt pulled another direction. What was that like? Which self won that time?

Two Selves, One Christ, Built Systems

  1. Which self did you find yourself inhabiting most this week—the old or the new? What specific moment or pattern made that real to you as Chris described it?
  2. Looking at our marriage together, where do we default to passivity instead of actively choosing the new self? What's one system we could redesign together to structurally promote godliness in that area?
  3. Christ is our complete pattern and curriculum for transformation. How can we pray for each other to know him more deeply and imitate him more deliberately in the daily rhythms of our life together?

Memory verse this week

Ephesians 4:22-24

You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; to be made new in the attitude of your minds; and to put on the new self, created to be like God in true righteousness and holiness.

Why this verse: This passage encapsulates the sermon's central framework of dual identity—the old self and new self—and establishes that transformation requires both putting off and putting on, which is the foundational tool upon which the entire message depends. It anchors the theological reality that sanctification is not passive spiritual experience but active, conscious choice to inhabit the new self created in God's likeness.
