Lecture 3-3: What Sin Costs
The last lecture named sin as a real, universal condition rather than an occasional mistake. This lecture takes the next honest step: naming what that condition actually costs. Scripture does not treat sin as a private, victimless inclination. It treats sin as something with real weight — it damages relationships, it distances a person from God, and, left unaddressed, it ends in something Scripture is not shy about calling death. This lecture stays deliberately short of the answer to all of this. The cross, and what it accomplishes, belongs to Chapter 4. Naming the cost honestly, without rushing to the relief, is this lecture's whole job.

- Name the relational, spiritual, and ultimate consequences of sin described in Romans 6:23 and Revelation 2:5.
- Explain what Romans 6:23 means by calling death the "wages" of sin, rather than an arbitrary penalty.
- Explain why this lecture does not yet discuss the cross or atonement, and why that is deliberate rather than an oversight.
- Identify what Revelation 2:5 calls its readers to do in response to having "fallen" from where they once were.
- Give an example, from ordinary life, of a relational consequence of sin distinct from its ultimate consequence.
For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord." — Romans 6:23
World English Bible
Remember therefore from where you have fallen, and repent and do the first works; or else I am coming to you swiftly, and will move your lamp stand out of its place, unless you repent." — Revelation 2:5

Romans 6:23 uses a specific, deliberate word — "wages" — the pay a worker has actually earned, not a punishment handed down arbitrarily from outside. Paul's point is that death is not an unrelated penalty attached to sin by decree; it is what sin actually produces, the way a day's labor produces a day's pay. Revelation 2:5, addressed to a real early church at Ephesus that had drifted from its earlier love and faithfulness, adds something this chapter needs just as much: consequence is not only about a distant, final reckoning. It is also about something that has already happened — a real "fall" from where a or a community once stood — and it comes paired with a real, present call: "remember," and "repent."
Three levels of cost
It helps to name sin's consequences at three distinct levels, because collapsing them into one flat idea of "punishment" misses how Scripture actually talks about this.
Relational. Sin damages trust between people in very ordinary, recognizable ways — a lie that makes a friend stop believing what you say even after you've told the truth ten times since; a betrayal that changes how safe a marriage feels years later; a pattern of using people that leaves someone genuinely alone despite being surrounded by others. Genesis itself frames the very first sin's first consequence this way: hiding from each other and from God (Genesis 3:7-10), before any punishment is even pronounced.
Spiritual. Sin also distances a person from God in a way that is not merely relational in the way two friends drift apart. Isaiah 59:2 states it plainly: "your iniquities have separated between you and your God" (WEB). A hardened conscience, a prayer life gone dry, a growing comfort with what once felt clearly wrong — none of these are automatic or permanent, but they are a real, spiritual cost this lecture would be dishonest to leave out.
Ultimate. And beneath both of these sits what Romans 6:23 names without softening: death — not merely biological death, which comes to believer and unbeliever alike, but death understood as the full, final outworking of a life lived turned away from the source of life itself. This is the most serious claim in the lecture, and it is stated here, deliberately, without yet being answered. That answer is coming. It is not coming in this lecture.
Why the cross waits until Chapter 4
It would be easy, and in some ways more comfortable, to move straight from naming this cost to relieving it. This lecture resists that on purpose. Sitting honestly with what sin actually costs — rather than rushing past it toward the good news — is itself part of taking the diagnosis seriously. A cure offered before the disease is taken seriously rarely changes how carefully a patient guards their health afterward. Chapter 4 will show, in detail, how the cross deals with exactly what this lecture has named. For now, the task is simpler and harder: to let the weight of Romans 6:23 and Revelation 2:5 actually register, without softening it in advance.
Revelation 2:5's answer: remember, and repent
Revelation 2:5 is not addressed to an unbeliever hearing the gospel for the first time. It is addressed to a real, established church — people already following Christ — who had nonetheless "left" their first love, drifted from where they had once been. Its call is worth noting carefully, because it does not despair: "remember... and repent." Remembering is not nostalgia; it is an honest look backward at what has actually changed. — turning back, "and do the first works" — is presented as genuinely possible, not as a formality. Consequence, in Scripture's own telling, is never presented as the end of the story for someone willing to turn back. It is presented as urgent precisely because turning back is still possible.
4-1. Three levels of cost
핵심 요약
- Sin's consequences operate at three distinct levels: relational (broken trust), spiritual (distance from God, Isaiah 59:2), and ultimate (death, Romans 6:23).
- Romans 6:23 calls death sin's "wages" — what sin actually produces, not an arbitrary penalty attached from outside.
- This lecture deliberately does not yet address the cross or atonement; that belongs to Chapter 4, after the cost has been taken seriously on its own.
- Revelation 2:5 addresses a real church that had drifted, calling it to "remember" honestly and "repent" — consequence named as urgent because turning back remains genuinely possible.
- Naming sin's cost honestly does not contradict 3-1's dignity or 3-2's condition; it is the next honest step after both.
| Front | Back |
|---|---|
| Romans 6:23 | The wages of sin is death - what sin actually produces, not an arbitrary penalty. |
| Three levels of cost | Relational (broken trust), spiritual (distance from God), ultimate (death). |
| Revelation 2:5 | "Remember... and repent" - addressed to believers who had drifted, not to outsiders. |
| Why no cross yet | Chapter 4 answers this cost; this lecture's job is naming it honestly first. |
★ One sentence to remember Sin's cost is real at every level - relational, spiritual, and ultimate - and naming it honestly comes before answering it.
✓ This week's action Think of one relationship where sin - yours or another's - has cost real trust. Without rushing to fix it this week, simply name to yourself, honestly, what was actually lost.

묵상 및 토론
- Which of the three levels — relational, spiritual, ultimate — feels most concrete to you from your own experience? Which feels most abstract?
- Romans 6:23 calls death sin's "wages" rather than an arbitrary penalty. Does that change how you think about consequence?
- The lecture deliberately withholds the answer (the cross) until Chapter 4. Was it uncomfortable to sit with sin's cost without immediately moving to relief? Why might that discomfort be worth something?
- Revelation 2:5 is addressed to believers who had drifted, not to unbelievers. Have you ever recognized, in your own life, a "first love" you had drifted from?
- What is the difference, in your own words, between remembering as nostalgia and remembering as Revelation 2:5 seems to intend it?
