Matthew 18:15-20 July 16, 2017 Pastor Chris Oswald
Audio coming soon
Thesis God's special presence—the ultimate privilege of the church—will be manifest when believers gather in His name with deadly seriousness about sin, which means individuals must humble themselves and expose hidden sin while the church receives the broken with grace and maintains holiness through biblical discipline.

The shape of the argument

Pastoral correction · unit #14
"Oswald applies the theological principle to a specific pastoral concern: you may be reluctant to commit fully to this church because of how it has handled secondary matters (buildings, budgets, staff), but the solution is not withdrawal but pressing in together to seek God's presence, which will sort out all those secondary concerns."

Illustrations· 3
  1. God's Special Presence Through History historical example · unit #9 — Oswald surveys redemptive history from Old Testament Israel through the incarnation to Revelation, showing the consistent pattern that God's people prosper when His presence is with them and fail when it departs, using examples like Israel's military defeats, Mary's blessing (Emmanuel), and Christ's threat to remove the lampstand from unfaithful churches.
  2. God's Presence Prevents Idolatry in the New Creation hypothetical · unit #16 — Oswald uses the eschatological vision of the new heavens and new earth to illustrate the principle: material blessings will exist there without becoming idols because God's overwhelming presence keeps everything in proper perspective, showing the solution is not removing blessings but increasing awareness of God's presence.
  3. Faith the Size of a Mustard Seed historical example · unit #26 — Oswald uses the Matthew 17 mustard-seed-faith passage to illustrate his interpretive approach: when Jesus makes an extreme-sounding promise that doesn't match our experience, the problem is likely our failure to meet the condition (genuine faith) rather than Jesus overstating the promise.
Theological claims· 8
  1. Christ's manifest presence in the gathered church (verse 20) is the ultimate privilege that serves as the foundation for all other church blessings, including legislative authority and answered prayer. unit #6
  2. God's special presence is what makes the church special, and throughout Scripture when God's presence departs (Ichabod), His people lose their uniqueness and capability. unit #8
  3. All the church's special powers and privileges are entirely dependent on God's special presence—when that presence goes away, the church loses all unique capability and becomes powerless. unit #10
  4. When the church loses God's special presence but retains its structural blessings (authority, resources, power), those blessings inevitably become instruments of destruction rather than blessing. unit #12
  5. Jesus' consistent comfort when He calls us to hard things is not optimism or self-esteem but the promise 'I am with you.' unit #19
  6. God's presence serves two essential functions for believers: it gives perspective that prevents blessings from becoming idols, and it gives power to endure the burdens of obedience. unit #22
  7. Gathering 'in His name' is significantly harder than it sounds because it requires a group of self-centered sinners to come with a genuinely unified agenda of seeking the Lord, which only happens through serious sanctification and Holy Spirit work. unit #27
  8. One essential element of gathering in Jesus' name is being deadly serious about sin, and throughout Scripture God's special presence is consistently tied to the purity of His people. unit #29

0 · Oswald opens by directing the congregation to Matthew 18 while establishing pastoral credibility through a personal testimony about the privilege of pastoral work—seeing redemption 'up close and personal' like a baseball usher who loves the game gets to see it repeatedly

Good morning. Want to open your Bibles to the book of Matthew, uh, chapter 18. Matthew chapter 18. As you're turning there, let me just tell you that I have been very busy and very encouraged by my last couple of weeks. You don't get to see all that the Lord is doing. You don't get to see all that I get to see. I was telling someone this week, maybe it was last, that I'm convinced pastors become pastors for the same reason that ushers become ushers at baseball games. Have you ever known a guy who was an usher at a baseball game at Kauffman Stadium or Busch Stadium? I've known a few. You know, it doesn't pay that well, but they just really love baseball. And they get to see baseball up close and personal day after day after day. And the privilege of serving the Lord as a pastor is you get to see redemption up close and personal day after day after day.

1 · The pastor steps outside the exposition to address the congregation directly about what God is currently doing in their church—a process of undoing (razing) before rebuilding (raising) that involves exposing hidden sin to the light, which is uncomfortable but necessary for God's new work

And so I've met with several of you over the past several weeks and hope to continue to do that. And let me just tell you what's going on and why I'm so encouraged. You know, part of, part of God's movement in a group of people involves him undoing so that he can do a new thing. I often tell folks that before God can raise, R-A-I-S-E, us, he sometimes has to raze, R-A-Z-E, us. There's sometimes an undoing before God does a new work. And part of that undoing, part of that knocking over old sinful idols and so on and so forth is a revealing of sin, an exposing of sin to the outside world, to the light, a turning of things that had been hidden in darkness for quite some time out into the light. And I'll tell you point blank, that's never comfortable. It's never comfortable to go through that. It's never comfortable to walk with someone through that. But the Lord is doing that in our midst, and He's doing that because He is wanting to do a new work in our midst. And so you should, I just want you to be encouraged. There's no way you can be as encouraged as I am because I get to see it up close and personal, but I want you to be encouraged. The Lord is doing that in this church, and I hope that he's doing that actually in your life. That's part of what we're going to talk about today in Matthew chapter 18, and we're going to start reading in verse 15.

2 · Oswald reads Matthew 18:15-20 aloud, presenting Jesus' instructions for church discipline (the four-step process from private confrontation to church-wide action) followed by three escalating promises about the church's authority: binding/loosing, prayer agreement, and Christ's special presence

Says, if your brother sins against you, go and tell him his fault. Between you and him alone. If he listens to you, you've gained your brother. But if he does not listen, take one or two others with you, that every charge may be established by the evidence of two or three witnesses. If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be as a Gentile and a tax collector. Truly I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven. Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven. For where two or three are gathered in my name, there I am among them.

3 · Oswald signals the sermon's main focus within the larger series context—verse 20 and Christ's unique presence in the gathering—while acknowledging the passage contains other material he will address before arriving at the main point

Now, in our discussion of the presence of God, of the manifest presence of God, the part of that passage I just read that'll jump out to us is verse 20. For wherever two or more are gathered in my name, there I am among them. And that is in fact going to be the emphasis of this message. We're going to focus on this idea that somehow in the gathering Christ is uniquely present.

4 · Oswald identifies the structural pattern in verses 18-20: an ascending progression of promises ("but wait, there's more") that moves from lesser to greater blessings rather than the typical infomercial pattern of descending value, using the infomercial illustration to make the exegetical observation memorable

But I want to point a few things out about this text. I want you to notice the progression of benefits in this passage, the progression of benefits. There's a bit of a 'but wait, there's more' kind of vibe. Going on here. You guys like to watch infomercials? I was talking to somebody who actually enjoys infomercials. I like— his hands, yeah, yeah. I like watching infomercials too. And one of the things that always happens in the infomercial is, you know, "But wait, there's more!" And then you get another thing on top of it, and then another thing on top of that, and another thing on top of that. And so like half the infomercial is "But wait, there's more!" Now usually though, in infomercials, they bring out lesser stuff. Like the "But wait, there's more!" is like a steak knife. You know, and then the next, "But wait, there's more," is another steak knife. And so on and so forth. But what we see in this text from verses 18, 19, and 20 is a progression of blessings in the other direction. Not from greater to lesser, but from lesser to greater.

5 · Oswald unpacks the first two promises—binding/loosing (legislative authority) and prayer agreement (answered petition)—showing how verse 19's promise is actually bigger than verse 18's promise because it moves from the church's judicial authority to direct access to the Father's power through corporate prayer

So there are 3 promises in those 3 verses. You can look at your Bibles, 18, 19, and 20, 3 promises, and they progress in a bigger way, not a smaller way. The first one is what? "Truly I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven." That sounds like a pretty big deal. But wait, there's more. He says in the very next verse, "Again I say, if two of you agree about anything they ask, it will be done for them by My Father in heaven." You see the progression? At first he's saying, if you bind or loose anything on earth, it will be bound or loosed in heaven. Bind or loose just means forbid or permit. He's giving the church the authority to legislate, okay? And you're gonna be like, that's kind of scary. Well, it is if we don't follow God's word, right? So he's giving us this authority to bind and loose, to permit and forbid. And then He says, but wait, there's more. And He actually shows us that that blessing, that privilege that the Church has, that authority is rooted in a larger authority. He says, actually, it's not just your ability to legislate, to bind and loose. If two of you agree on anything on earth, about anything they ask, it will be done for them by My Father in Heaven. You see how it's gotten bigger?

Memory verse this week

Matthew 18:20

For where two or three gather in my name, there am I with them.

Why this verse: This verse captures the sermon's central promise: God's manifest presence in the gathered church is the ultimate privilege that undergirds all other blessings and powers. Memorizing it anchors the congregation in the reality that Christ's presence—not programs, structures, or secondary blessings—is what makes the church truly special and capable.

Small-group discussion

6 questions for your group this week

  1. What does Jesus promise in Matthew 18:20, and what does the preacher suggest this promise means for what makes the church truly special?
    Matthew 18:20
    → Can you think of a time when you've sensed God's presence in a gathered group of believers, and what was different about that gathering compared to others?
  2. Walk us through the sequence of Matthew 18:15-17. What do these verses reveal about the church's responsibility toward sin, and why do you think Jesus structures church discipline this way rather than leaving it to individuals alone?
    Matthew 18:15-17
  3. The sermon claims that gathering 'in His name' requires being 'deadly serious about sin.' What do you think that phrase means, and how is it different from merely addressing sin when it's convenient or obvious?
    → Where do you see this 'deadly seriousness' lacking in churches you know, and what do you think the cost of that lack is?
  4. According to the sermon, God's presence in the church serves two essential functions. What are they, and can you describe how each one directly addresses a real struggle believers face?

    Isaiah 42:3
    → What would need to change in how we relate to one another for that to become real?
  6. When you're tempted to withdraw from the church because of its dysfunction or your own sin, what does the gospel promise about Christ's presence that could compel you to press in instead of pull back?

Daily readings · Monday–Friday

5-day reading plan

This week we meditate on how God's manifest presence in the gathered church transforms everything—our perspective, our power, our purity—and how pursuing that presence requires deadly seriousness about sin.

Monday Luke 1-2

The angels sang and shepherds trembled at the announcement of Emmanuel—God with us. This was not merely theological abstraction but the arrival of God's tangible, transforming presence in flesh. When we gather in Jesus' name today, we are invited into that same reality: the presence of the living Christ among His people. This presence is not a secondary benefit but the foundation upon which every other church blessing—authority, answered prayer, unity—entirely depends.

Tuesday Hosea 2:23 / 1 Peter 2:9-10

Scripture traces a sobering pattern: once called 'my people,' Israel became 'not my people' when God's presence withdrew. Yet in Christ, that lost status is restored—we are called again 'my people,' recipients of mercy. Our distinctiveness as the church, our power to live differently from the world, flows entirely from God's presence dwelling in us. Without this presence, we retain the structure of the church but lose what actually makes us the church.

Wednesday Matthew 7:13-14

The narrow gate is not easy to find or walk, and fewer choose it because it demands a singular focus. When we gather in Jesus' name, we are choosing the narrow way together—rejecting the broad path of personal agendas, comfort, and hidden sin. This unified pursuit of holiness in community is the only gateway to experiencing His manifest presence. It requires us to lay down our self-centeredness and become genuinely united around the one agenda that matters: seeking the Lord with deadly seriousness.

Thursday Psalm 51:17

David's broken and contrite spirit—not external performance or sacrificial routine—was what the Lord desired. This same brokenness over sin is what opens the door to God's presence in the gathered church. When we hide our sin, we hide from God (Genesis 3), but when we expose our broken places to one another in the church, we become the kind of people God's presence delights to inhabit. Our corporate pursuit of holiness through honest repentance is not legalism but the very pathway He has promised.

Friday Isaiah 42:3

Jesus will not break the bruised reed or snuff out the smoldering wick; His presence brings healing, not condemnation, to the broken and repentant. Yet this same Jesus turned over tables in the temple and commanded church discipline for unrepentant sin. We reflect His character when we receive the repentant sinner with grace while refusing to shelter unrepentant sin. The narrow gate of God's presence demands both—tenderness toward those who confess and courage to address those who hide. This is how the church becomes truly holy and truly compassionate.

Pray together this week

Prayer for God's Presence and Corporate Repentance

Father, we come before You with grateful hearts, confessing that Your manifest presence in our gathered body is the ultimate privilege that gives us perspective on all lesser blessings and power for all our burdens. We marvel that You have promised to be with us when we gather in the name of Your Son, and we adore Your character as a God who draws near to the humble and broken (Psalm 51:17). Yet we confess with deep conviction that we often lack deadly seriousness about sin—both in our individual hearts and in our life together as a church. We hide from You as Adam hid in the garden; we rationalize, we minimize, we refuse to expose the hidden things that grieve Your Spirit. And we confess that we do not always receive the broken with the tenderness of Christ, nor do we maintain the holiness our gathered worship demands (Matthew 18:15-17).

But the gospel humbles us with the news that Christ has already borne our sin in His body on the cross, and His blood cleanses us from all unrighteousness. We are not called to earn His presence through our perfection but to experience it through our repentance—individual repentance that gets radical with hidden sin, and corporate repentance that welcomes the broken while guarding the purity of Your people (Isaiah 42:3). In the gospel we have both the comfort of His steadfast presence and the power to put sin to death.

Grant us, we pray, the grace to gather in Your name with genuine unity of purpose, each of us willing to humble ourselves and expose the sin that would grieve Your Spirit. Give us tender hearts toward one another in our weakness, yet uncompromising devotion to the holiness that Your presence demands. When we face the hard things You call us to do—difficult conversations, necessary discipline, the costly work of sanctification—remind us that Your comfort is not optimism but the reality of Your presence with us (Matthew 18:20). And compel us by Your grace to press into corporate pursuit of Your presence, that all secondary blessings might fall into their proper place and our church might know the privilege of gathering before the all-glorious, triune God.

To You alone be the glory, both now and forever. Amen.

Sunday-evening family table

When God Shows Up

For the parent

This prompt invites your family to reflect on what changes when Jesus promises to be present with us—not as an abstract comfort, but as a real difference-maker in how we live together. Listen for how your children understand God's presence as both a privilege and a responsibility.

Jesus promised that when we gather together in His name, He will be right there with us. What's one way that knowing Jesus is actually present with us—not just somewhere in heaven, but with us—should change how we treat each other in our family this week?

God's Presence and Our Repentance

  1. What did the sermon help you see about God's presence in our church gathering, and where do you sense the Holy Spirit inviting you to greater seriousness about sin in your own heart?
  2. Where might we as a couple be settling for the structure or comfort of our marriage while neglecting the pursuit of Christ's actual presence—and how could we press into genuine unity around seeking Him together?
  3. What sin or pattern of pride do you sense the Spirit wanting to surface between us, and how can we each pray for the other's willingness to repent and experience the freedom of Christ's presence in our marriage?
