Built Upon the Cornerstone (Preach)

Bible Passage: Ephesians 2:17–22

Main Idea of Pericope (Ephesians 2:11–22): Paul teaches that Gentiles who were once far from God and excluded from his people have now been brought near through the death of Christ, who has made peace by creating one new people reconciled to God and joined together as his dwelling place.

MIT: Paul teaches that through Christ both Jews and Gentiles now share equal access to the Father and are being built together into God’s household and dwelling place by the Spirit.

MIS: Christ brings us in; and on the Word, the Spirit builds us into God’s house.

Introduction

Some of the strongest emotions we feel are tied to one word: belonging.

You can be in a room and still feel like you’re not supposed to be there.

Wrong clothes.

Wrong background.

Wrong people.

Wrong story.

And spiritually, that’s how many people live:

close enough to hear about God…

but not sure they belong near God.

Paul says the gospel doesn’t merely improve outsiders.

It brings them in.

And it doesn’t leave them isolated—it builds them together into a home where God dwells.

Where we’re headed today: the essence of the sermon

Christ brings us in; and on the Word, the Spirit builds us into God’s house.

What I’m asking you to do from the start:

Stop lingering like an outsider if Christ has brought you in.

And build the church the way God builds his house—on his Word.

1. Peace Proclaimed: Christ brings us in.

Ephesians 2:17

Read/quote the verse

“And he came and preached peace to you who were far off and peace to those who were near.”

Exposition

Notice first: “and”—this continues the cross-work Paul just described.

Then: “he came and preached”

Jesus “preaches peace” in a way that reaches Gentiles and Jews.

The most natural sense: the risen Christ continues his ministry through the gospel proclamation—through his apostles, by his Spirit.

When the gospel is preached, Christ is not absent. He is speaking.

What does he preach?

“peace”—and he repeats it: peace…peace.

This is Isaiah-shaped language: peace to the far and the near.

Who are the groups?

Far off = Gentiles.

Near = Jews.

And here’s the key:

The peace in this verse is not mainly ethnic peace yet.

It’s peace to both groups with God.

Both need reconciliation. Both receive the same message.

Illustration (radio message to the far off)

Imagine being lost out at sea—no shoreline, no bearings, fuel running low.

It’s getting dark and you are running out of time.

Then the radio crackles: “This is the Coast Guard. We have your coordinates. Stay on this channel.”

The message itself is a lifeline.

You don’t get rescued by swimming back—you get rescued because help has found you.

That’s what Paul is saying: Christ preaches peace to the far off. Reconciliation starts with a word from him.

Application

If you are “far off” in your own mind—shame, guilt, distance—

hear this: Christ doesn’t say, “Get closer first.”

He preaches peace to the far off.

Church: reconciliation begins with a word—the gospel is for you.

The simple, clear gospel of peace is what calls us to reconciliation

Not “good vibes”.

Not mere moralism.

Peace proclaimed in Christ.

Transition

But what is this peace, practically?

Peace has a concrete shape: access.

If peace is real, it means you can draw near.

2. Access Secured: Christ, in one Spirit, to the Father

Ephesians 2:18

Read/quote the verse

“For through him we both have access in one Spirit to the Father.”

Exposition

Verse 18 starts with “for”—this is the basis of the peace proclaimed.

Key word: access

Not merely permission in theory.

Not tolerance, but acceptance.

Indeed, God invites us into his presence!

Approach—drawing near into God’s presence.

Worship-language: being brought near before God.

Quote Romans 5:1-2

“Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ. Through him we have also obtained access by faith into this grace in which we stand, and we rejoice in hope of the glory of God.”

Then Paul stacks the gospel in three phrases—Trinitarian clarity:

By Trinitarian - I mean that our fundamental belief is that the one and only one living God is three in person.

Our unwavering conviction is that the God in Scripture is three-in-one

(tri-une)

It is mysterious, but true.

One nature, one essence, one will - but three distinct persons,

so, the Father is God, the Son is God, and the Holy Spirit is God.

but the Father is not the Son, and the Son is not the Spirit, and the Spirit is not the Father.

And each person is distinguished by personal properties.

We have seen this already in chapter 1

v4 - the Father plans redemption: he chose us from eternity past.

v7 - the Son accomplishes redemption: he died on the cross for our sins.

v13 - the Holy Spirit applies redemption: he seals us for the day of redemption.

Notice here the prepositions in chapter 2

Through him — Christ is mediator, the way in.

In one Spirit — one Spirit, one people; no separate track.

To the Father — reconciliation’s goal is home with God.

And Paul emphasizes: “we both”

Equal access.

No second-class Christians.

No Gentile courtyard vs inner court.

Remember the veil? What happened when Jesus died on the cross?

Same Father. Same Spirit. Same access. Same Christ.

Illustration (Gator Boosters skybox — “she’s with me” access)

I still remember the one time I got invited into a Gator Boosters skybox for a home game in The Swamp—and it was against the Tennessee Volunteers, so the place was electric.

I was a broke college student. I didn’t have the designer clothes. I didn’t have the fancy investor vocabulary. I definitely didn’t look like I belonged in that room.

But a friend of mine had access—she belonged there. And one day she invited me and my best friend and said, “Come with me.”

I’ll never forget walking up to that entrance. Everything about it communicated, “This is not for you.” The atmosphere, the people, the confidence—like a different world.

But then she stepped forward, greeted the staff like she knew them, and it was basically the same message: “They’re with me.”

And just like that, we walked in. Not because we could talk our way in. Not because we looked like we belonged. Not because we earned anything. We had access because of her.

That’s a faint picture of what Paul is saying in Ephesians 2:18:

“Through him we both have access… to the Father.”

We don’t get into God’s presence because we have the right outfit,

the right résumé,

or the right spiritual vocabulary.

We have access because of Christ—the mediator—who brings us in.

Application

Some of you pray like you still don’t have access:

always apologizing,

always hesitant,

always assuming God is irritated with you.

The gospel says: through Christ, you don’t knock like a stranger.

You come as a child.

Not because you’re clean—but because Christ is faithful.

Church: our unity is not due to compatibility or charisma.

Our unity is not based on the fact that we share similar hobbies.

Our unity is not because we like the same music or movies.

Our unity is that we both have access to the Father in one Spirit through Christ.

Transition

If we share access to the Father, then our identity can’t stay the same.

Outsider language must die.

Paul now draws the conclusion.

3. Status Changed: Outsiders become citizens and family.

Ephesians 2:19

Read/quote the verse

“So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God…”

Exposition

“So then” = consequence.

Access changes status.

Paul uses social categories his hearers would feel:

strangers — outsiders passing through

aliens/resident foreigners — near, but never fully belonging

Then he reverses it:

fellow citizens with the saints

full belonging with God’s people.

members of the household of God

not guests in the hallway.

not tolerated outsiders.

family.

This is both:

relational identity (God as Father; we as family)

and spatial identity (a household; a home; a place we belong)

Illustration (lunch table)

Middle school lunch tables can be brutal: “You can’t sit here.”

People spend years feeling like they’re always the odd one out—always looking for a seat.

The gospel does the opposite: Christ doesn’t just let you stand in the doorway—he gives you a seat at the table.

“No longer strangers… but fellow citizens… members of God’s household.”

Application

This is why the church can’t be an audience and a stage.

it’s a household.

family knows names,

bears burdens,

forgives,

serves,

corrects with love.

Cornerstone:

we move toward outsiders because Christ moved toward us.

we don’t treat people as “potential consumers.”

we treat them as “future family” by grace.

Outsiders should find a door open, a table set, and a people ready.

Transition

But Paul doesn’t stop at “family.”

He goes further: God doesn’t only give us a family.

God makes us his house—his dwelling place.

4. House Built: On the Word, aligned by the Cornerstone, indwelt by the Spirit

Ephesians 2:20-22

Read/quote vv. 20–22 (or key phrases)

Built on the foundation…

Christ Jesus himself the cornerstone…

the whole structure grows…

built together into a dwelling place for God by the Spirit…

A) On the Word — the foundation (v. 20)

Paul says the household is “built on the foundation of the apostles and prophets.”

There are a handful of perspectives on what Paul means here.

Here is how I understand it:

When Paul says the church is “built on the foundation of the apostles and prophets,” he’s describing how God laid the foundation once in the earliest days of the church.

The apostles were uniquely chosen and commissioned by Jesus—authorized witnesses who could speak for Christ with authority and help establish the church in the true gospel.

The prophets here are best understood as New Testament prophets

Spirit-gifted spokesmen God used in that foundational season to strengthen and establish the church in sound doctrine,

especially while the New Testament was still being written and circulated.

So the picture is this: In the early church,

God was still delivering and solidifying the apostolic gospel,

and the Spirit used apostles and prophets as agents of revelation

for that foundational period.

But here’s the key: foundations are laid once. You don’t keep relaying a foundation every generation.

Once the foundation is down, you build on it.

That’s why the church today does not look for new revelation or fresh “foundation layers.”

We are not waiting for new apostles.

There are no more apostles.

We are not dependent on prophets to deliver new words from God.

God has already given his church what it needs:

a complete, sufficient Bible—the 66 books of the Old and New Testaments.

So when we say we’re built on the “apostles and prophets,” we mean:

we are built on the once-for-all, apostolic-prophetic revelation

which is preserved and delivered to us in Holy Scripture.

And then Paul makes it even more concrete:

Christ Jesus himself is the cornerstone—the aligning, load-bearing stone.

Scripture is the foundation God has given.

Christ is the center and the line.

And the Spirit builds the church on that foundation into God’s dwelling place.

The point is not personality.

The point is foundation—a Word-given, gospel-revealing foundation.

God’s house is Word-founded.

The church is built on revealed truth—not human guesses.

Not whatever works.

Not whatever trends.

Apostolic-prophetic gospel foundation.

B) Aligned by the Cornerstone — Christ himself (v. 20)

“Christ Jesus himself” is the cornerstone.

He is distinct.

He is central.

Cornerstone = alignment and stability.

He sets the line.

He bears weight.

He holds the structure together.

The church is not ultimately held together by:

gifted leaders,

common preferences,

shared politics,

or strong personalities.

Christ holds the line.

This cannot be emphasized enough.

The head of the corner is not only the first stone laid, it is the most important stone laid.

It aligns the building.

It gives the structure stability.

And in a time when churches are tempted to compromise for worldly culture,

Or, entertain people to tickle their fancy,

We are striving to be a church made up of living stones

But the foundational and determinative Stone is Jesus Christ.

C) Indwelt by the Spirit — the goal (vv. 21–22)

Present tense everywhere:

joined together; grows; being built together.

The building is a holy temple and a dwelling place for God.

God dwells with his people by the Spirit.

not a dead monument,

a living, growing, Spirit-indwelt home.

Illustration (unseen foundation)

No one walks into a home and says, “What a beautiful foundation.”

They notice the kitchen, the paint, the lighting, the décor.

But the foundation decides whether the whole house stands or cracks.

Same with the church: a church can have nice “fixtures,” but if it isn’t built on the Word, it won’t hold.

Persuasive Cornerstone application: why Word-built matters

If Christ brings us in… then the only question is: what will we build on?

Programs don’t lay foundations.

Personalities don’t lay foundations.

Aesthetics don’t lay foundations.

Money doesn’t lay foundations.

The Word lays foundations.

What Word-built Cornerstone looks like:

Preaching: we expose the text and submit to it.

Worship: we sing truth, pray Scripture, confess sin honestly, announce grace clearly.

Discipleship: we form people with the Word, not trends.

Decisions: we ask “what is true?” before “what is popular?”

Unity: we unite around Christ revealed in Scripture.

Closing Application (practical + persuasive: Cornerstone must be Word-built)

Now bring it home to Cornerstone:

If Christ brings us in…

then the only question is: what will we build on?

Paul is clear:

God builds his house on the Word,

aligned by Christ,

indwelt by the Spirit.

So a church can be:

busy and still be shaky.

growing and still be crooked.

exciting and still be hollow.

Because:

programs don’t lay foundations.

charisma doesn’t lay foundations.

aesthetics don’t lay foundations.

money doesn’t lay foundations.

nostalgia doesn’t lay foundations.

The Word lays foundations.

What does “Word-built Cornerstone” look like?

Preaching: we expose the text and submit to it.

Worship: we sing truth, pray Scripture, confess sin honestly, announce grace clearly.

Discipleship: we form people with the Word, not with trends.

Decisions: we ask “what is true?” before “what is popular?”

Unity: we don’t unite around preferences; we unite around Christ revealed in Scripture.

And we depend on the Spirit:

not to replace the Word,

but to use the Word to build the house.

Conclusion (warm invitation)

If you feel far off:

hear the gospel: Christ preaches peace to the far off.

through him you have access to the Father.

If you belong to Christ:

stop living like an outsider.

you are citizens.

you are family.

and you are part of God’s house.

So let’s respond:

Come in—through Christ, draw near.

Build right—Cornerstone, let’s be Word-built, Christ-aligned, Spirit-dependent.

Refrain (repeat to close):

Christ brings us in; the Word builds us up.
