The Consecrated Community

Sanctified for Mission John 17:17–23; Acts 2:42–47

Introduction: When We Protect Something Too Much

Have you ever had something so special that you were afraid to use it?

When I was young, my mom found a Chicago Cubs t-shirt at a local K-Mart in the middle of Pittsburgh Pirates country in central Pennsylvania. That kind of find was rare. I opened it, held it, admired it—and then carefully tucked it away in my drawer. I didn’t want it stained. I didn’t want it torn. I didn’t want anything to happen to it.

One day, I finally decided to wear it. I ran to my room, pulled it out, and put it on—only to discover something tragic had happened.

It didn’t fit anymore.

In trying to preserve it, I lost the opportunity to enjoy it.

Sometimes the church does the same thing.

We treasure holiness. We value truth. We guard our community carefully. But if we misunderstand consecration as insulation rather than mission, we may preserve something so tightly that we fail to participate in the very purpose for which God set us apart.

Tonight we consider this truth:

Consecration is not withdrawal from the world but preparation for participation in Christ’s redemptive mission.

I. Consecrated for the World (John 17:17–18)

In John 17, Jesus is in the Upper Room. Judas has left. The cross is hours away. The Synoptic Gospels emphasize Gethsemane’s agony. John emphasizes something else: Christ’s priestly prayer.

Jesus prays:

“Sanctify them in the truth; your word is truth.” (John 17:17)

The Greek verb hagiazō (ἁγιάζω) means “to set apart,” “to consecrate,” “to dedicate for sacred use.”

But notice what follows:

“As you sent (apostellō) me into the world, so I have sent them into the world.” (John 17:18)

Consecration leads to sending.

And the purpose clause in verse 21—hina (ἵνα)—makes the intention unmistakable:

“So that the world may believe.”

Holiness is teleological. It has direction. It has purpose.

God told Israel in Exodus 19:6 that they would be “a kingdom of priests.” Peter echoes it in 1 Peter 2:9—“a chosen race… that you may proclaim.”

Set apart — so that you may go.

Christological Center

Verse 19 deepens this:

“For their sake I sanctify myself.”

Jesus consecrates Himself. This anticipates the cross. Hebrews 13:12 says He suffered “to sanctify the people.”

Our holiness derives from His holiness. Our consecration flows from His self-offering. He is both sanctified and sanctifier (Hebrews 2:11).

We are not set apart by our effort. We are set apart because Christ set Himself apart for us.

When Jesus prays in John 17:21,

“That they may all be one, just as you, Father, are in me, and I in you…”

He grounds ecclesial unity not in shared preference, shared culture, or even shared mission strategy—but in the inner life of God.

The language reflects what later theology would call perichōrēsis (περιχώρησις)—the mutual indwelling and interpenetration of the Father, Son, and Spirit. Though the term itself emerges in later patristic reflection, the reality is embedded in John’s Gospel.¹

Notice the structure:

“You, Father, are in me”

“I am in you”

“I in them”

“You in me”

“That they may become perfectly one” (17:23)

This is not mere cooperation. It is communion.

The preposition en (ἐν, “in”) signals relational participation, not spatial containment. Jesus is not describing proximity; He is describing shared life.

The Son eternally receives life from the Father (John 5:26). The Spirit proceeds as the bond of love (cf. John 15:26). The divine life is not solitary but self-giving. The Triune God exists as holy communion.

And now—astonishingly—Jesus prays that this communion be extended to His disciples.

Unity, then, is not strategic. It is ontological participation in divine love.

N. T. Wright observes that in John 17 the church’s unity is the visible sign that “the life of heaven has begun on earth.”² The church becomes the historical embodiment of Trinitarian communion.

This reframes everything.

We are not merely united for mission. We are united in God’s own life—and therefore sent.

The hina clause (“so that the world may believe”) does not reduce unity to utility. Rather, mission flows from participation. The world encounters the Triune God when it sees a people whose love reflects divine self-giving.

Christ’s own consecration in verse 19—

“For their sake I sanctify (hagiazō) myself”

—means that He sets Himself apart to draw humanity into Trinitarian fellowship through the cross. As Athanasius wrote, “He became what we are that He might make us what He is.”³

Holiness, then, is not sterile separation. It is participation in the self-giving love of the Triune God.

And participation always becomes proclamation.

To The Desert

If John 17 reveals the prayer for participation in divine communion, Acts 2 shows us what that communion looks like when embodied in history.

Throughout church history, believers have wrestled with how to remain holy in a compromised world.

When persecution subsided and Christianity became culturally secure, many feared that comfort would dilute devotion. If martyrdom was no longer possible, how could discipleship remain costly?

So some fled.

They withdrew into deserts. They embraced silence, fasting, ascetic rigor. What had once been red martyrdom became what historians call “white martyrdom” — dying to the world through renunciation.

Their longing was sincere.

Basil of Caesarea questioned extreme solitude, asking, “Whose feet will you wash? Whom will you serve?”³

Gregory the Great warned that the pastor must sometimes leave contemplation to serve: “The love of truth seeks a holy leisure; the demand of charity accepts righteous labor.”⁴

Even within early monasticism, there was recognition that holiness finds its completion in service.

They desired to give themselves wholly to God.

And we must honor that.

The Desert Fathers preserved discipline. They modeled seriousness about sin. They refused complacency.

But John 17 presses further.

Jesus does not pray, “Remove them.”

He prays, “Sanctify them… as you sent me.”

Consecration (hagiazō) is inseparably tied to sending (apostellō).

Out of The Desert

The Son’s devotion to the Father was not expressed through distance from humanity but through incarnational presence among them.

As Athanasius wrote in On the Incarnation, “He became what we are that He might make us what He is.”¹

The holiness of the Son is not fragile distance; it is redemptive descent.

Augustine reminds us, “God loves each of us as if there were only one of us.”²

Divine love is not abstract devotion; it is personal, relational, near.

Jesus binds love of God and love of neighbor together (Matthew 22:37–39). John intensifies it:

“Whoever does not love his brother whom he has seen cannot love God whom he has not seen.” (1 John 4:20)

Devotion to God must incarnate itself in love of neighbor.

This is not an indictment of monasticism. It is a recognition that the church, in every generation, must relearn the full shape of obedience.

At times the church has had to relearn Matthew 28:

“Go therefore and make disciples of all nations.”

William Carey insisted, “Expect great things from God; attempt great things for God.”⁵

Consecration that does not attempt becomes incomplete obedience.

Consecration was never meant to terminate in isolation. It was meant to mature into participation.

The Upper Room was necessary.

But it was never permanent.

Pentecost breaks the doors open.

If John 17 gives us the prayer, Acts 2 gives us the picture.

II. The Visible Consecrated Community (Acts 2:42–47)

Pentecost does not produce isolation. It produces movement. The Spirit pushes the church into the streets.

Acts 2:42 says they “devoted themselves.” The Greek proskartereō implies persistent, habitual fidelity.

Four pillars shape their life:

Apostolic teaching

Fellowship (koinōnia)

Breaking of bread

Prayers

And what happens?

They share possessions.

They worship together.

They eat together.

They praise God.

They have favor with the people.

And:

“The Lord added to their number daily.”

Their consecrated practices created a credible witness.

Jesus had prayed for unity “so that the world may believe.” Acts shows that prayer being answered.

The church is not preserved in a drawer. It is worn in the world.

John Wesley declared, “The gospel of Christ knows of no religion but social; no holiness but social holiness.”⁶

Holiness is not perfected in isolation but in love embodied in community.

Illustration: The Broken Finger

There is a story of a young boy playing basketball. He went up for a shot. A defender’s hand came down hard and broke his finger.

His father saw the bandage and asked, “Did you make the shot?”

The boy smiled and said, “Nailed it.”

The doctor taped the broken finger to a healthy one so it would heal correctly.

The church is like that.

Broken people come in. They are bound to healthy community. They are strengthened. And then they go back into the game.

We are not a museum of preserved saints.

We are a training ground for mission.

III. The Human Problem: Fragmented Holiness

But we struggle here.

1. Individualized Spirituality

Modern Christianity often equates holiness with private morality. But Hebrews 10:24–25 commands us to stir one another to love and good works.

Holiness in Scripture is communal.

2. Tribal Ecclesiology

Unity becomes “us versus them.” Insiders and outsiders. Paul rebukes Corinth for this in 1 Corinthians 1:10–13.

Unity is not uniformity. It is participation in Trinitarian love.

3. Activism Without Abiding

Some churches emphasize mission but neglect formation.

Jesus says in John 15:5:

“Apart from me you can do nothing.”

Mission without sanctification leads to burnout. Sanctification without mission leads to stagnation.

Both distort the gospel.

Sin curves us inward (incurvatus in se). Pride protects what God intended to give away.

If sin fragments and distorts, how does the Gospel restore?

IV. The Gospel Answer: A Cruciform, Spirit-Filled People

A. The Cross Consecrates

John 17:19 anticipates Golgotha.

Jesus’ holiness is cruciform. He sets Himself apart not for safety—but for sacrifice.

Holiness is not fragile. It is resilient love under pressure.

B. The Spirit Sends

Acts 2 begins with fire and wind.

The Spirit does not create retreat. The Spirit creates witness.

1 Corinthians 12:13 says we are baptized into one body.

Unity is Spirit-generated diversity reconciled in Christ.

C. Participating in the Son’s Mission

In John 20:21, Jesus repeats it:

“As the Father has sent me, even so I am sending you.”

The church does not invent mission.

The church participates in the eternal sending of the Son.

We are a visible sign of the Kingdom breaking into the world.

V. How We Live Into Consecrated Mission

If we speak of consecration, we must speak carefully—and in a Wesleyan key.

For John Wesley, sanctification was never mere moral refinement. It was the restoration of the imago Dei for holy love.⁴

Wesley understood salvation through the movement of grace:

Prevenient grace awakens.

Justifying grace pardons.

Sanctifying grace restores.

Sanctification is not withdrawal from the world; it is the Spirit’s work of healing the will so that we may love God and neighbor rightly.

Wesley famously declared, “The gospel of Christ knows of no religion but social; no holiness but social holiness.”⁵

He did not mean that holiness is achieved socially, but that holiness is expressed relationally. Love cannot mature in isolation. It requires neighbor.

This aligns precisely with John 17.

Jesus prays not merely for individual purity but for communal participation in divine love. Holiness is perfected in unity because God’s own holiness is relational.

Randy Maddox describes Wesley’s theology as one of “responsible grace”—grace that restores our capacity to respond in love.⁶ Sanctification, then, is empowerment for participation in God’s mission.

Holiness that terminates in self-protection is arrested development. Holiness that matures into love becomes missionary.

Consider Acts 2.

The Spirit descends. The community forms. Possessions are shared. Bread is broken. Prayers ascend. And “the Lord added to their number daily.”

Sanctification becomes visible.

In Wesleyan theology, Christian perfection is not flawlessness—it is perfect love. And perfect love necessarily moves outward.

The Spirit who sanctifies is the Spirit who sends.

To seek holiness without mission is to misunderstand grace. To pursue mission without holiness is to exhaust the flesh.

Wesley held these together: Justification births peace with God. Sanctification births love for the world.

The church, therefore, is not a refuge from history. It is a Spirit-formed community through which the love of God spills into history.

Transition: If sanctifying grace restores us for love, then the practices we embody must cultivate that love in concrete, visible ways.

So how do we live this out?

Irenaeus described the Son and Spirit as the “two hands of the Father” reaching into the world.⁷

The Church, caught up in that sending love, becomes an instrument of divine embrace.

1. Truth-Formed Teaching

(2 Timothy 3:16–17) Doctrine shapes devotion.

2. Accountable Fellowship

(James 5:16; Hebrews 3:13) We bind broken fingers to healthy ones.

3. Sacramental Centrality

(1 Corinthians 10:16–17) At the Table, we remember that we are one loaf, one body.

4. Radical Generosity

(Acts 2:45; 2 Corinthians 8–9) Kingdom economics confront self-preservation.

5. Unified Love

(John 13:35) “By this all people will know…”

Love is the apologetic.

Abiding (John 15) and sending (John 17) are inseparable.

Depth fuels witness.

Conclusion: Set Apart Together for the Sake of the World

Psalm 133 says unity is where God commands blessing.

Acts 2 shows unity is where God commands growth.

John 17 reveals why:

Sanctified in truth

Unified in love

Sent in mission

Empowered by the Spirit

Christ consecrated Himself. Christ formed a people. Christ sends that people.

The church is not a fragile keepsake to be tucked away.

We are consecrated for the world.

So the question is not: How do we protect what we have?

The question is: How faithfully will we wear the holiness Christ has given us — for the life of the world?

Amen.

Romans 10:14 “How then will they call upon him in whom they have not believed? And how will they believe in him about whom they have not heard? And how will they hear about him without one who preaches to them?”
