Comfortable Certainty

November 13, 2024 Pastor Chris Oswald
Thesis Genuine assurance of salvation can only exist when we understand that God saves us entirely by his grace through Christ's mediation, not through any merit or partnership on our part, and this understanding frees us from the impossible burden of measuring our own worthiness.

Pastoral correction · unit #22
"Concludes the argument with pastoral appeal: embrace the objective Lutheran system which frees you for honest introspection without existential dread. Directly addresses doubters, urging them to rest in the truth that God saved them out of pure pity through Christ's mediation, not their merit."

Illustrations· 1
  1. hypothetical · unit #21 — Extended hypothetical illustration imagining raising children in an Erasmian Catholic household. Argues that works-based assurance systems must suppress questions of heart motive (because they destroy assurance), producing legalistic, hypocritical, comparison-driven cultures fixated on sins of commission rather than love.
Theological claims· 14
  1. Assurance is a Christian believer's confidence that he or she is in right standing with God and that this will result in ultimate salvation. unit #1
  2. Pride is the first major obstacle to assurance because human-centeredness makes us seek merit-based security rather than receiving salvation as a pure gift. unit #2
  3. Some believers have a psychological disadvantage to gaining assurance due to melancholic temperament — the eyes of their soul are tinted, making even objective truth appear darker than it really is. unit #3
  4. Melancholic temperament creates obstacles to enjoying assurance not because of weak faith but because it creates obstacles to enjoying everything — some believers face genuine hardware limitations in accessing emotional certainty. unit #4
  5. The debate over assurance can be understood through the 500-year-old Erasmus-Luther divide, with Erasmus representing synergistic traditions and Luther representing monergistic traditions — how you understand salvation determines how you understand assurance. unit #7
  6. Erasmus and Luther differ fundamentally on what God saves us from: Erasmus believes God saves us from a tendency to sin (leaving capacity for obedience), while Luther believes God saves us from bondage to sin (total inability to do good). unit #8
  7. Luther and Erasmus fundamentally disagree on human ability: Erasmus believes God's commands imply human capacity to obey them, while Luther argues man is so broken he cannot escape sin without God's sovereign intervention through the Spirit. unit #10
  8. Erasmus believes God saves those who make themselves fit subjects for grace through meritorious works, but Luther (and Scripture) teaches God saves for his own glory out of sheer pity — not because we deserve it but because he has chosen to glorify himself through our salvation. unit #11
  9. Sin functions like the autonomic nervous system — you can modify it temporarily but cannot escape it voluntarily; we need saving from this involuntary bondage, and God saves us out of pure pity for his own glory, not because we merit anything. unit #14
  10. For Erasmus, salvation is synergistic — humans contribute something (faith, cooperation) from remaining capacity, making salvation a partnership rather than a monergistic act of God. unit #15
  11. For Luther, salvation is monergistic substitutionary atonement — God saves through an outside mediator (Moses typologically, Christ perfectly) who pays for sin entirely, not through partnership but through substitution. unit #16
  12. The New Testament's revelation of Christ as the perfect mediator enables objective assurance, grounded in texts like John 10:28-29 where Jesus uses an absolute negative ('shall not by no means ever perish') to guarantee eternal security. unit #17
  13. Synergistic salvation systems (Erasmus and his theological descendants) cannot provide genuine assurance because they leave subjective questions ('Did I believe enough?') unanswerable — truth in advertising requires admitting their system does not include assurance. unit #18
  14. Luther's 'comfortable certainty' is possible only when salvation is entirely God's work — freed from dependence on my performance, I rest in God's faithfulness, power, and fatherly compassion, knowing he pardons my failures and makes me better. unit #19
Quotations· 11
"If the eyes of the soul are tinted, then even the sun will appear darker than it really is." — Thomas Brooks (unit #3)
"An individual may have a strong faith, much grace and rich evidence of fruitful service, yet lack full assurance because of natural temperament. We are, after all, physio psychological unities a melancholic disposition. A melancholic disposition de facto creates obstacles to the enjoyment of assurance partly because it creates obstacles to the enjoyment of everything." — Sinclair Ferguson (unit #4)
"Let all the free will in the world do all it can with all its strength. It will never give rise to a single instance of ability to avoid being hardened if God does not give the spirit or of meriting mercy if it is left to his own strength." — Martin Luther (unit #8)
"This work of man removes a barrier which had kept God from giving grace. The barrier removed is man's unworthiness for grace, which God gives only to those who are fit for it. With the gift of grace, man can do works which he before could not do, and God rewards these gifts with salvation. Therefore, with the help or aid of the grace of God, a man merits eternal salvation." — Garrett Ericks (unit #11)
"For my sake, for my sake, I do this. I will not yield my glory to another." — God (through Isaiah) (unit #11)
"A man performs by his own strength, making him a fit subject for the gift of eternal grace." — Erasmus (as quoted by Garrett Ericks) (unit #11)
"While most people believe God saves people for people's sake because of his attraction to them and his inner compulsion to promote and honor them, Psalm 106, 8 tells us that God is in the business of saving sinners for his own namesake, that is, for his own honor, promotion, and glory." — Mike Faberaz (unit #11)
"The first Adam says, blame me, blame my wife. And then the second Adam, Jesus Christ, says, don't blame my wife, blame me." — R.C. Sproul (unit #16)
"They shall never perish. He says, literally, we can translate this. They shall not by no means ever perish. This is an absolute, unequivocal, unassailable negative. Would Jesus have said this if in fact many of his sheep shall perish, if so much as one true child of God can ever perish? Jesus has deceived us." — Sam Storms (unit #17)
"I frankly confess that for myself, even if it could be, I should not want free will to be given to me, nor anything to be left in my own hands to enable me to endeavor after salvation. Not merely because in face of so many dangers and adversities and assaults of the devil, I could not stand my ground, but because even were there no dangers, I should still be forced to labor with no guarantee of success." — Martin Luther (unit #18)
"But now that God has taken my salvation out of the control of my own will and put it under the control of his and promised to save me not according to my working or running, but according to his own grace and mercy, I have the comfortable certainty that he is faithful and will not lie to me and that he is also great and powerful, so that no devils or opposition can break him or pluck me from him. Furthermore, I have the comfortable certainty that I please God not by reason of the merit of my works, but but by reason of his merciful favor promised to me, so that if I work too little or badly, he does not impute it to me, but with fatherly compassion pardons me and makes me better. This is the glory of all the saints in their God." — Martin Luther (unit #19)

0 · Opens the podcast by framing the topic (assurance of salvation from Exodus) and providing transparency about the sermon preparation process — explaining why this topic was deferred from Sunday's pulpit message to the podcast format

Welcome to the Providence Podcast. My name is Chris Oswald, senior pastor at Providence Community Church. Thank you so much for tuning in. Today we're going to cover a topic I thought I'd be preaching on last Sunday, and that is the issue of Assurance in the Book of Exodus. Assurance in the Book of Exodus. The title that I had had planned for that message was Comfortable Certainty, which comes from a section of Martin Luther's famous book, the Bondage of the Will, which a number of theologians have said is by far Luther's best work. So we're going to talk about how a person who is a Christian can be assured of their salvation. And this is a topic that I had just picked up on in my reading, not only of the Book of Exodus, but also I was reading through the Bondage of the Will, and Erasmus is the freedom of the will. And I'll get into all that in a moment. And up until, I guess, Saturday. I planned on bringing this message to the pulpit last Sunday, and I just started growing uncomfortable with the connection to the text itself. It's a good topic. It's a good thing to talk about, but I just didn't feel like I was getting really at the heart of the text. And that happens to me a lot because I read a lot of things. I read a lot of wide, you know, a wide variety of sources, and I just have that kind of synthesizing mind where I see connections. And so it's pretty common for me to get, you know, halfway through the week and realize, you know, I've been doing all this work in this one direction. And, yeah, everything here is true, but is it really the heart of the text that we have before us? And so I abandoned this as the sermon for Sunday and talked about leadership instead, which I felt was the main point of that particular passage. But today I'm going to just walk through what I discovered as I was working on this issue of assurance and the issue of assurance of salvation in the Book of Exodus in general.

1 · Establishes the working definition of assurance using D

Define assurance. First of all, G. A. Carson's definition is helpful. A Christian believer's confidence that he or she is in right standing with God and that this will result in ultimate salvation assurance. According to DA Carson, a Christian believer's confidence that he or she is in right standing with God and that this will result in ultimate salvation.

2 · Introduces the first of three obstacles to assurance (pride) and begins to establish the argument's structure

Now, there are three obstacles. This is an issue that comes up a lot. I've struggled with assurance in the past, and I've certainly helped a number of people over the years figure out kind of where they stood with God. And battling these issues of assurance. And there are three obstacles that I've learned to see rather reliably manifesting when someone is struggling to get assurance, to get a confidence that they are indeed Christ and that they are indeed headed to heaven. And the first one is just pride. We'll talk about this plenty. But there is a level of human centeredness in all of us that struggles to receive the gift of salvation apart from works and looks to some way of earning things as a way that feels more sure. And so one of the things we'll talk about is pride. Lot of people just struggle with more pride than they realize, which, you know, is always kind of funny because it's obviously a huge issue. But one of the reasons why people sometimes struggle to be comfortably certain in their salvation is pride.

3 · Introduces the second obstacle (neuroticism/melancholy) as a psychological rather than spiritual barrier

The second one is one I don't hear about talked about at all, and I think it really needs to get discussed, and that is neuroticism. So I would say the first issue is spiritual pride, but the second issue is psychological. What I would refer to or think of as neuroticism. Here's what I wish more pastors had said to me when I was younger and struggling with this. I wish that this was just a bigger part of the preaching on this subject, and that is something like this. I wish pastors would say, some of you have a dispositional disadvantage to gaining comfortable certainty. Some of you have a dispositional disadvantage to gaining comfortable certainty. I think it's very important to just embrace that older understanding of human nature that says that we don't all have equal access to all good things. We're not given equal hands. I don't have equal access to a really great vertical jump. For instance. I could make my vertical jump better, but I'm starting at a certain place and have a certain kind of ceiling there, as it is with vertical jump. Or I've talked to a number of people who've excelled all the way to the edge of their mental hardware in the area of mathematics. So they're really smart and they're really good at math, and then they hit a spot in their learning where they literally just lack the CPU processing to go any further. So we all have dispositional disadvantages. And some people have a dispositional or psychological disadvantage to gaining insurance, to gaining insurance, to gaining assurance. You may be more prone psychologically to neuroticism, to melancholy, and so on and so forth. And I think in part because of the diet and the. The just. There was a lot of, I think, physical strikes against the puritans but they had. Well, they were very familiar with struggling through melancholy and depression. And. And it was. It was Thomas Brooks, the Puritan Thomas Brooks who said that if the eyes of the soul are tinted, then even the sun will appear darker than it really is. If the eyes of the soul are tinted, then even the sun will appear darker than it really is. And some people just have a disposition to melancholy.

4 · Reinforces the neuroticism claim with Sinclair Ferguson's authority, emphasizing the physio-psychological unity of human beings and the unequal distribution of dispositional access to assurance

Sinflair Ferguson said it this an individual may have a strong faith, much grace and rich evidence of fruitful service, yet lack full assurance because of natural temperament. We are, after all, physio psychological unities a melancholic disposition. A melancholic disposition de facto creates obstacles to the enjoyment of assurance partly because it creates obstacles to the enjoyment of everything. So one of the things I want you to know about assurances is not as easy to get. For every single kind of person, there's a kind of person who has the eyes of their soul tinted. Everything seems a little darker than it really is. A melancholic disposition will just create an obstacle to assurance, an obstacle to enjoying assurance because it creates an obstacle to enjoying everything. It's going to be harder for some of you to have assurance than others. And that's partly just because of your own hardware.

5 · Turns the psychological observation into direct pastoral counsel: work on pride, not just temperament

Now, some of you, and I put myself in this case as a young man, some of you have a double whammy. You are both prideful and melancholic. So you've already got two strikes against you and you're really going to struggle with getting assurance. And listen, man, I get it. I honestly do. But here's my counsel. As someone who has worked through a lot of this stuff in my own soul for the last 30 years, here's what I would tell you. Get to work on your pride. The melancholy is more rooted in your pride than you understand. I'm not saying it's entirely rooted there. It is more rooted there than you understand. So do what you can to pursue humility. And I think you will see that like the tint on your. The eyes of your heart gets lighter. I believe there is some connection, not an ultimate connection, but some connection between a perpetually depressed heart and a prideful heart. Not everybody that's prideful is perpetually depressed. Some people that are prideful are haughty and glib and, you know, assume the world revolves around them. But many people who struggle with pride, they do that pride manifests itself in general unbelief and in a general sense that everything revolves around them only in a negative way. And so I do believe that there are some people who have some limitations that are spiritual pride. There's some that have some limitations, psychological neuroticism. And then there's some of us who got the double whammy. And we are both prideful and neurotic. And what I would tell you is, is that you need to work on your pride. The disposition will soften over time. You'll become less prone to neuroticism as you age. That's just a pretty well established principle. And one of the reasons for that is you'll learn to take yourself way less seriously.

John 10:28-29
This passage directly grounds the sermon's central claim that objective assurance is possible only in a monergistic framework where salvation rests entirely on God's work, not human performance—Jesus' absolute negative ('shall not by no means ever perish') provides the theological foundation for 'comfortable certainty' in Luther's sense. It anchors assurance not in subjective feeling or human effort but in Christ's mediatorial power and the Father's sovereign protection.
Small-group discussion

6 questions for your group this week

  1. Chris distinguished between two fundamentally different understandings of how salvation works — one where humans contribute something to their own rescue, and one where God does the entire work. What did you hear as the key difference between these two approaches, and why does that difference matter for whether we can have real assurance?
    → Can you think of a time when you've felt pressure to 'do enough' spiritually to secure your standing with God? What was that pressure rooted in?
  2. The sermon described pride as a major obstacle to assurance — specifically, the impulse to seek security through our own merit rather than receiving salvation as a pure gift. Where do you see that impulse showing up in your own heart, and what makes it so appealing?
    Isaiah 48:11
  3. Chris also addressed melancholic temperament — the reality that some believers face genuine psychological difficulty accessing emotional certainty, not because their faith is weak but because of how their mind is wired. If this describes you or someone close to you, what would it mean to build assurance on theological truth rather than on your emotional experience of that truth?
    → How might addressing pride actually lighten the psychological tint you're looking through?
  4. Jesus's promise in John 10:28-29 uses an absolute negative — 'they shall not by any means ever perish.' What does that kind of language do for your confidence in God's grip on your salvation, and how does it differ from assurance systems that leave you asking 'Have I done enough?'
    John 10:28-29
  5. If your salvation rests entirely on Christ's mediation and not on your performance, how does that change the way you can look at your own sin and failure this week? What becomes possible that wasn't possible before?
    → What's the difference between examining your heart honestly and living in existential dread about whether you're 'still saved'?
  6. Luther called this kind of assurance 'comfortable certainty' — freedom from dependence on your performance, resting in God's faithfulness and fatherly compassion. What would change in how you live, pray, or relate to others if you actually believed that kind of comfort was yours in Christ?
    John 10:29

5-day reading plan

This week we trace the gospel foundation of assurance from God's glory-centered character through the substitutionary work of Christ, learning how Luther's comfortable certainty rests entirely on God's monergistic salvation rather than human merit.

Monday Isaiah 48:11

Isaiah declares that God acts 'for my own sake' — his glory, not our worthiness, is the animating motive of salvation. This shatters the pride that seeks merit-based security; we are saved not because we have made ourselves worthy, but because the all-glorious God has chosen to demonstrate his power and compassion through our redemption. When we grasp that our salvation glorifies God rather than validates us, we are freed from the exhausting performance of self-justification.

Tuesday John 10:29

Christ's declaration that no one can snatch us from the Father's hand is not qualified by our future obedience, our emotional stability, or the strength of our faith — it is grounded in the Father's power and vigilance. This objective promise replaces the synergistic question ('Have I believed enough?') with the monergistic reality: my security rests entirely on the Father's grip, not my grasp. We rest secure not because we are strong, but because we are held by one who cannot fail.

Wednesday 1 Corinthians 6:19-20

Paul reminds us that we have been 'bought with a price' — Christ's blood is the currency of our redemption, not our cooperation or merit. The language of purchase makes clear that someone else has paid what we cannot pay; we are not partners negotiating a deal, but slaves redeemed at infinite cost by a compassionate Master. This substitutionary reality demolishes the Erasmian illusion that we contribute something meritorious; instead, we are freed by an alien righteousness applied to us entirely by grace.

Thursday Romans 8

The Spirit himself witnesses alongside our spirit that we are God's children — not because we feel it, but because he has adopted us into the family through Christ's mediation. This divine testimony is objective reality; it stands even when our melancholic soul-eyes see only darkness, even when our emotions betray us. We learn to believe the Spirit's testimony over the voice of our fluctuating feelings, anchoring certainty not in vibes but in the unchanging faithfulness of God.

Friday John 10:28

Jesus' promise that he gives eternal life to his sheep, and they shall never perish, is the bedrock of our peaceful assurance. Because Christ has accomplished our salvation completely, we are freed to examine our hearts honestly, see our sin without existential dread, and pursue growth as the grateful response of a pardoned child to a faithful Father. This is the comfortable certainty that comes from resting not in our performance, but in the One who performed our redemption entirely.

Pray together this week

Assured in Christ's Mediation

Father, we come to you marveling at your character — your holiness that demands satisfaction, your power that accomplishes all your counsel, and your fatherly compassion that moves you to save not because we deserve it but because you delight to glorify yourself through our redemption. We confess that pride so easily deceives us into seeking security through our own performance, and that many of us bear the weight of melancholic temperament, which tints our perception of even your clearest promises darker than they truly are. Yet we do not despair, for in the gospel we have been set free from the impossibility of earning your favor. Christ, our perfect mediator, has paid our debt entirely — not as our partner in a fragile cooperation, but as our substitute, bearing the full weight of our bondage to sin and purchasing us with his blood (1 Corinthians 6:19-20). By his finished work, we are no longer subject to the terrifying question, 'Have I done enough?' because our standing rests wholly on his faithfulness, not our fluctuating performance.

We ask you, O God, to deepen our grasp of this comfortable certainty week by week. For those among us who struggle with pride, give us humble eyes to see that we are saved purely by grace, that our works contribute nothing to our acceptance. For those whose melancholic hearts make assurance feel distant, remind us that your objective promises in Christ (John 10:28-29) do not depend on how we feel them — they stand sure regardless of our emotional weather. Grant us courage to examine our hearts honestly, to see our sin and pursue growth without existential dread, knowing that conviction itself is the Holy Spirit's testimony that you have already claimed us and will never let us go. Make us a people freed to love you not from fear of abandonment but from grateful wonder at your fatherly care. To you alone be glory, for you have accomplished all things for us in Christ.

When You Can't Feel Certain

For the parent

This prompt invites kids to wrestle with the difference between *feeling* sure and *knowing* something is true — a distinction the sermon makes for assurance. Listen for whether they naturally separate feelings from facts; help them see that God's promises don't change based on how we feel.

In the sermon, Pastor Chris talked about how some people's hearts make everything seem darker than it really is — kind of like wearing sunglasses that turn everything gray, even on a sunny day. If that's you, or if you know someone like that, here's the question: If God promised you something really important — like 'I will never leave you' — and you *believed* that promise was true, but you *felt* scared or sad anyway, would the promise still be true? Why or why not?

Resting in Christ's Certainty

  1. What struck you most about the sermon's claim that assurance comes entirely from Christ's work rather than our own effort—and did that stir relief, resistance, or something else in your heart?
  2. Where do we tend to slip into performance-based thinking in our marriage—measuring ourselves by how well we're doing rather than resting in God's grace toward us together?

Memory verse this week

John 10:28-29

I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father's hand.

Why this verse: This passage directly grounds the sermon's central claim that objective assurance is possible only in a monergistic framework where salvation rests entirely on God's work, not human performance—Jesus' absolute negative ('shall not by no means ever perish') provides the theological foundation for 'comfortable certainty' in Luther's sense. It anchors assurance not in subjective feeling or human effort but in Christ's mediatorial power and the Father's sovereign protection.
