Are Legalism and Licentiousness Really Equal Threats?

October 9, 2024 Pastor Chris Oswald
Thesis Modern evangelicalism's treatment of legalism and licentiousness as equal threats is both biblically and experientially false—licentiousness is far more destructive, and our fear of over-applying Scripture leaves us unable to recognize and combat sin in its early stages.

Pastoral correction · unit #7
"Oswald applies the developmental model of sin directly to the listener's life, explaining that sins begin small and grow if not confessed and put to death. He acknowledges the discomfort of the illustration while maintaining its essential point: early intervention in sin's development is critical."

Illustrations· 2
  1. analogy · unit #5 — Oswald uses his own fetal-to-adult development as an analogy for how sins exist in different developmental stages. Lust is to adultery as a fetus is to an adult—the same entity at different stages of growth. This makes the concept of sin's progression concrete and memorable while acknowledging the illustration's limitations.
  2. historical example · unit #10 — Oswald uses the historical pattern of post-revolutionary fascism as an illustration of humanity's deep need for boundaries. When societies throw off all restraint and experience the resulting chaos, they over-correct toward authoritarianism because lawlessness reveals destructive forces that threaten civilization itself.
Theological claims· 5
  1. The Puritan maximalist approach to interpreting God's law—seeking to apply it as broadly and deeply as possible—is superior to modern evangelicalism's minimalist approach, which fears over-application and thus misses wisdom and good application. unit #1
  2. God's maximalist view of sin reveals that humanity is far worse than we think—he sees hearts, intentions, and all potential violations we miss because we are desensitized to sin. unit #4
  3. Modern evangelicalism's anti-legalism and minimalist hermeneutic creates flat, oversimplified theology that leaves believers unable to recognize sin in seed form and thus constantly surprised by full-grown sin. unit #8
  4. Contrary to the common evangelical teaching that legalism and licentiousness are equally dangerous ditches, licentiousness is far more destructive—biblically, logically, and experientially—and poses a much greater threat to individual and societal flourishing. unit #9
  5. The Westminster divines' maximalist approach to Scripture—seeking to shed maximum light by identifying sin in all its developmental stages—aligns with Jesus's own method and serves human flourishing far better than minimalist approaches. unit #11

0 · Oswald opens the podcast with personal context about recording difficulties and situates the episode within the ongoing Ten Commandments sermon series

Foreign. Welcome, welcome, welcome. Long time. Welcome to the Providence Podcast. My name is Chris Oswald, senior pastor at Providence Community Church, and it has been quite some time since I've been able to record a podcast. Now, this is all due to the fact that I keep getting relocated. I am, I am a stranger and a sojourner in my own office spaces, but every time I lose an office space, something happens. I wind up having to sort of figure out a new configuration for the podcast. And we're, we're up and running with, I think, probably what will be a makeshift situation until probably about a month from now until we'll be able to turn one of the spare bedrooms in my house into a little bit of a studio space. I'm looking forward to that. Looking forward to more regular podcasting. Well, today is the 9th of October. It's a Tuesday. No, it's a Wednesday. And we've already had a sermon on adultery last Sunday. And we're wrapping up, we're getting ready to wrap up the Ten Commandments series soon. This week coming up, we'll be talking about stealing.

1 · Oswald contrasts two hermeneutical approaches: the Puritan maximalist method that seeks to extract maximum light and application from Scripture, and the modern evangelical minimalist method driven by fear of legalism

One of the things that I've noticed through this series is that you can take sort of a maximalist perspective on interpreting and applying these. And that's what you see the Puritans doing. That's what you see in the Westminster Confession or the Westminster Catechism and the Heidelberg Catechism and so on and so forth. And so most of my study work for this sermon series has been really in that kind of 1600s, 1700s, a little bit of the 1800s time period where people really treated God's word as a light. And they were like, okay, here's the truth. How can we apply this to as many places as possible and get the most out of this idea as possible? I've referenced some of this in a couple sermons, that there is a maximalist sort of perspective that so loves the Word of God that it meditates on it day and night and seeks to figure out how do we apply this text to as many places as possible? How do we get as much light out of this text as possible? And then there's another perspective that I would say is just very modern and evangelical. And the big fear, of course, in evangelicalism, wrongly, in my opinion, is legalism. And so the fear is always to over apply God's word to places where it doesn't speak specifically and so on and so forth. And boy, I'll just tell you, that is not the way that our forefathers handled the word of God, as you can see, if you would read these catechisms and confessions and so forth, they are really eagerly looking for places to apply these truths as far out as possible. Whereas we are so concerned about, you know, about putting something on someone, putting an expectation on someone that is beyond what the Bible does, that we're so concerned about that that we miss a lot of opportunities for wisdom and good application of God's Word. In the Westminster Confession, we see the phrase good and appropriate, or something like that. I can't remember it exactly, but it's this idea that the Word teaches what it teaches, and then there are good and appropriate implications of what it teaches that apply to other places in life as well. I bring all that up because we've seen that the. When we turn to say the commandment about taking the Lord's name in vain, and then we turn to the Westminster Catechism, we see all of these areas that we would not have thought about. The Same is true with adultery and murder and so on and so forth. And so you'll see some of that again this Sunday, Lord willing, if I'm able to preach, then you'll see that again. You'll see this interpretive maximalism. I would argue that that's really from the Lord, that that perspective, that approach is really from the Lord. And I want to kind of walk you through some scriptures today, specifically on the last two commandments, murder and adultery. So I want to point you to the development we see over time that is obviously led by God himself.

2 · Oswald reads Matthew 5:21-26 and demonstrates how Jesus himself employs maximalist interpretation by expanding the commandment against murder to include anger and insult

And that would show up in St. Matthew, chapter 5, verse. Let me read that to you. Matthew 5. 21. You have heard that it was said to those of old, you shall not murder, and whoever murders will be liable to judgment. But I say to you that everyone who is angry with his brother will be liable to judgment. Whoever insults his brother will be liable to the council, and whoever says, you fool, will be liable to hellfire. So if you are offering your gift at the altar, and they remember that your brother has something against you, leave your gift there before the altar and go first, be reconciled to your brother, and then come and offer your gift. Come to terms quickly with your accuser while you are going with him to court, lest your accuser hand you over to the judge, and the judge to the guard, and you be put in prison. Truly, I say to you, you'll never get out until you have paid the last penny. So here you have an example of Jesus doing this very same thing we see that the catechists are doing, and that is that there's this commandment, do not murder. And to apply that in a very strict and compartmentalized way would be to miss the heart behind the commandment. What Jesus is doing in Matthew 5, 21:26 is he showing the heart behind the commandment. And that heart includes anger. And now we can go to the next section in Jesus teaching in Matthew 24, in Matthew 5 and see that he does the exact same thing with the command related to adultery.

3 · Oswald reads Matthew 5:27-30 and shows Jesus expanding the adultery commandment to include lustful intent

Listen to Matthew 5:27. You have heard that it was said, you shall not commit adultery. But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart. If your right eye causes you to sin, tear it out and throw it away, for it is better that you lose one of your members than that your whole body be thrown into hell. And if your right hand causes you to sin, cut it off, throw it away. For it is better that you lose one of your members than the whole body, that your whole body go to hell. So here again, same idea. We see the strict commandment itself in Exodus 20. You shall not commit adultery. And rather than keep it exceedingly tight and say, well, this only applies in this one way, Jesus says, no, there's layers to this, and there are other implications that go beyond them. The most obvious one, he says here that if you look at a woman with lustful intent, you've already committed adultery with her in your heart.

4 · Oswald draws a theological implication from Jesus's maximalist interpretation: God sees far more sin than we do because he sees hearts and intentions, and his perfect holiness means he is not desensitized to sin as we are

Now, what I want you to understand is that there's a dynamic going on here that I haven't been able to figure out in another way. I only have one good illustration for this, but I don't love it, if that makes sense. But let me share it with you, because maybe you'll be able to see why I don't love it. But I think it's probably the right one. Okay, so what we get from this development we see from Exodus to Matthew is that, first of all, we get the idea that God really. God really was seeing a lot more potential violations of these commandments than we would see. And so it just reminds you that, my goodness, what the view of humanity must look like from God's perspective, who sees perfectly, who sees hearts and intentions, and who's so holy too, you know, he's not in any way desensitized to sin like we are. We're super desensitized to sin and he isn't. And you just realize, like, oh, my goodness, like, what? What must we look like to him as a people? You know collectively, because it's a lot more than. It's a lot worse than you would think, that's for sure.

5 · Oswald uses his own fetal-to-adult development as an analogy for how sins exist in different developmental stages

So there's one idea, the other idea is just that, and this is the illustration I don't love, but I don't know how else to talk about it, is that sins tend to have like a, almost like a, a fetus to 50 year old kind of range, if that makes any sense. Like, okay, so here's. I'm me, right? I'm almost 51 year away. And I was born in 1975, in August. So let's picture me in, let's say May of 1975. Where was I in May of 1975? Did I exist? Yeah, I did. I was in my mama's belly, you know, I was hanging out there, just like doing the Midwestern, you know, fetal thing, the Midwestern fetus, you know, growing up on corn and you know, all that stuff. So yeah, I was around. I wasn't the same as I am now, but it was me. It was me back in April of 1975, you know, and so the idea being that I'm me now. I was me then, but I'm definitely, you know, a much bigger me now than I was then. And I'm just more developed. I mean, just in general, you know, lots of cellular division has taken place. Well, that's. I think you see a glimpse of that in Jesus's teachings on these sins. It's like, is looking at a woman with lust in your heart adultery? Yes. Is it the same as sleeping with a woman who's not your wife? No, it is in the same. It's the same species. Is that the way we should say this? It's just a smaller version. And if it's allowed to continue to grow, it will grow into this bigger thing, typically. But even in the smaller thing, it's still sin. So it's still a sin. It's still the same kind of sin. It belongs to the same species, I guess. And it's just a question of how far it, its development does it get. And so, you know, I was me in, you know, March of 1975, just a lot smaller, simpler version of me. And now, all these years later, I'm still the same person, but I'm just, I've just expanded and grown.

Christians have moved from Mount Sinai (terror under the Law with Moses as mediator) to Mount Zion (peace in the Gospel with Jesus as mediator), but the mandate to worship God alone has not changed — only now we are empowered by the Holy Spirit who writes the Law on our hearts and fuels obedience through remembrance and gratitude.

5-day reading plan

This week we trace how God's maximalist view of sin—seeing hearts, intentions, and sin's early stages—calls us to recognize and confess corruption before it grows to full expression, equipping us to flourish rather than be blindsided by our own desires.

Monday Exodus 20:14

The commandment 'You shall not commit adultery' stands as God's bare statement, yet Jesus will show us that lust in the heart violates this command long before physical betrayal occurs. We begin here to see that God's concern is not merely outward conformity but the whole trajectory of the human heart—and His law, properly understood, illuminates that trajectory so we might arrest sin before it blooms into ruin.

Tuesday James 1:12-15

James maps sin's progression with surgical precision: desire gives birth to sin, and sin, when full-grown, brings forth death. Yet how many of us notice the early stirring—the glance that lingers, the thought we entertain, the whisper we don't immediately reject? This passage shows us that licentiousness thrives in our blindness to these seeds, and our modern reluctance to name sin's early forms leaves us vulnerable to its full, destructive expression. The gospel calls us to wake up and see.

Wednesday Psalm 2

The psalmist invites the nations to serve the Lord with fear and rejoice with trembling—a posture of trust in His absolute reign. When we grasp that God's maximalist interpretation of His law flows from His perfect knowledge of how we flourish, we stop resisting His penetrating gaze into our hearts as oppressive and begin to receive it as the loving wisdom of a sovereign King. His concern for our hidden motives is not legalism; it is fatherly care.

Thursday James 1:12-15

Notice that James does not warn us primarily against being too strict with ourselves; he warns against the slow, almost imperceptible journey from desire to conception to birth to death. A church that teaches 'don't worry about the small stuff' or minimizes the significance of internal motions leaves its members as sitting targets for the full-grown sin that will devastate their lives and witness. Licentiousness masquerades as freedom but delivers bondage; maximalist vigilance, by contrast, is the path to true liberty.

Friday Exodus 20:14

Return to the seventh commandment with new eyes: God's prohibition of adultery encompasses the lustful glance, the entertained fantasy, the half-hearted resistance to attraction. As we gather tomorrow for corporate worship, we are called to examine our hearts ruthlessly—to confess not only the sins we have committed but the movements toward sin we have permitted. This is what dying to sin looks like: not waiting for catastrophe to force repentance, but killing corruption at the root through the power of Christ.

Pray together this week

Prayer for Eyes to See Sin in Its Seeds

Father, we come before you with gratitude for your piercing gaze that sees not only our outward actions but the intentions and desires of our hearts (Matthew 5:28). We adore you as a God of perfect holiness who cares infinitely more about the roots of sin than merely its fruit, who pursues our deepest transformation rather than surface compliance. Your law is not a burden to minimize but a gift to maximize—a pathway to true flourishing and freedom.

We confess that we have often been blind to sin in its earliest stages, comfortable with small compromises and hidden longings that we rationalize away. We have grown desensitized to the whispers of temptation, mistaking silence for safety, and then we stand shocked when those seeds grow into full-grown transgressions that devastate our lives and witness (James 1:14-15). We have absorbed an evangelical minimalism that fears over-application of God's law and thus leaves us spiritually unprepared, vulnerable to the very licentiousness that destroys far more than legalism ever could.

Grant us, O God, the grace to see ourselves as you see us—to recognize that lust begins in a glance, that hatred germinates in a harsh word, that disobedience starts in a small resistance to your will (Matthew 5:21-26). In the gospel, Christ has defeated the power of sin at its root and restored us to right relationship with you, freeing us to pursue genuine obedience not from fear but from joy. We have been given your Spirit to mortify sin before it multiplies, to confess it early, and to experience the daily renewal that only comes through the finished work of your Son.

We ask you to cultivate in us a maximalist hunger for holiness—not a legalistic striving, but a glad pursuit of righteousness that recognizes sin's full trajectory and addresses it in its seed form. Give us courage to examine our hearts honestly, to name the small temptations and hidden desires, and to bring them into the light of confession and repentance. Make us a people who treasure your law as the expression of your wisdom and love, and who experience in that obedience the deep peace and flourishing you intend. To this end, strengthen us by your grace and make us faithful witnesses of your transforming power.

Sunday-evening family table

When Does a Thought Become a Sin?

For the parent

This prompt invites your family to wrestle with Jesus's teaching in Matthew 5:28 that looking at someone with lust is adultery in the heart. The goal is to help kids understand that sin doesn't start when we act—it starts much earlier, in our thoughts and desires—and that recognizing sin early helps us ask Jesus for help before it grows.

Jesus said that looking at someone with lust in your heart is the same as committing adultery. That seems really strict, doesn't it? Why do you think Jesus cares about what we're thinking and wanting, not just what we actually do? Can you think of a time when a small wrong thought or feeling grew into something bigger if you didn't stop it?

Seeing Sin Before It Grows

  1. The sermon challenged us to recognize sin in its early stages rather than wait until it's fully grown—what small, hidden temptation or desire did the message help you see more clearly in your own heart this week?
  2. How might we help each other grow in spotting sin's beginnings in our marriage—the small compromises, resentments, or desires we're tempted to overlook—rather than waiting until they've become destructive patterns between us?
  3. What is one specific area where you sense the Spirit inviting you toward greater vigilance and repentance, and how can I pray for and encourage you as you pursue that gladness in obedience?
