Untitled Sermon (2)

Introduction — When the Mission Ignites

There is a difference between believing in a mission and being mobilized for a mission.

A rescue boat tied to the dock is still a rescue boat — but it is not rescuing anyone. A fire station full of trained firefighters is ready — but until the alarm sounds, no one is being saved.

In Acts 1, Jesus gave the mission:

“You will be my witnesses…” (Acts 1:8 NIV)

But He told them to wait — because the mission requires power.

Acts 2 is the alarm bell. Acts 2 is the launch moment. Acts 2 is when the church becomes a moving, witnessing, mission people.

And what we learn here is this:

A church on a mission is:

Empowered for the mission

Proclaiming the mission message

Calling people into the mission

Living as a mission community

1. A Church on a Mission Is EMPOWERED by the Spirit

Acts 2:1–13

“All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.” (Acts 2:4)

The mission begins with divine empowerment.

Jesus had already told them this would happen:

“Do not leave Jerusalem, but wait for the gift my Father promised.” (Acts 1:4)

“You will receive power when the Holy Spirit comes on you; and you will be my witnesses.” (Acts 1:8)

Power is given for witness.

Not comfort only — but communication. Not experience only — but proclamation.

The miracle of languages at Pentecost shows God immediately pushing the church outward.

“We hear them declaring the wonders of God in our own tongues!” (Acts 2:11)

Supporting Scriptures

This follows the pattern of God empowering His messengers:

“Not by might nor by power, but by my Spirit,” says the Lord Almighty. (Zechariah 4:6)

“The Spirit of the Lord is on me, because he has anointed me to proclaim good news…” (Luke 4:18)

“Our gospel came to you not simply with words but also with power, with the Holy Spirit…” (1 Thessalonians 1:5)

Mission is never sustained by human energy alone — it is Spirit-enabled.

Illustration

A lighthouse does not exist for itself — it shines outward to save lives. The Spirit fills the church so the light goes out.

Transition

The Spirit supplies the power — now comes the proclamation. Because a mission church must speak a mission message.

Point 2 — A Church on a Mission Proclaims the Gospel Clearly

Acts 2:14–36

Peter stands and preaches Christ. Mission preaching is always Christ-centered preaching.

“Then Peter stood up… and addressed the crowd.” (Acts 2:14)

He explains Jesus’ life, death, resurrection, and lordship.

“God has made this Jesus… both Lord and Messiah.” (Acts 2:36)

Mission is not spreading religion — it is proclaiming Jesus as Lord.

Supporting Scriptures

This matches the consistent apostolic message:

“For what we preach is not ourselves, but Jesus Christ as Lord.” (2 Corinthians 4:5)

“I resolved to know nothing while I was with you except Jesus Christ and him crucified.” (1 Corinthians 2:2)

“How, then, can they call on the one they have not believed in? … And how can they hear without someone preaching to them?” (Romans 10:14)

Mission requires proclamation — not assumption.

People are not saved by church presence alone — but by gospel truth spoken.

Restoration Movement Emphasis

This is why we emphasize returning to apostolic preaching — Scripture opened, Christ proclaimed, response invited.

Mission drifts when Christ is replaced with trends. Mission stays true when Christ stays central.

Illustration

If a cure for a deadly disease exists, the most loving act is not to admire it — but announce it.

Transition

When the gospel is proclaimed clearly, hearts are confronted — and mission always moves toward decision.

Point 3 — A Church on a Mission Calls for a Biblical Response

Acts 2:37–41

“They were cut to the heart and said… ‘What shall we do?’” (Acts 2:37)

Mission preaching aims at response — not applause.

Peter answers:

“Repent and be baptized… for the forgiveness of your sins.” (Acts 2:38)

That is not tradition — that is apostolic instruction.

Supporting Scriptures

This response pattern is consistent throughout the New Testament:

Repentance

“Repent, then, and turn to God, so that your sins may be wiped out.” (Acts 3:19)

Belief

“Believe in the Lord Jesus, and you will be saved.” (Acts 16:31)

Baptism

“Whoever believes and is baptized will be saved.” (Mark 16:16)

“We were therefore buried with him through baptism into death…” (Romans 6:4)

“This water symbolizes baptism that now saves you also…” (1 Peter 3:21)

Mission includes calling people not just to think — but to respond in obedient faith.

Mission Result

“Those who accepted his message were baptized.” (Acts 2:41)

Mission is not complete at proclamation — it continues through invitation.

Illustration

A lifeguard doesn’t just shout, “There’s danger!” — he shouts, “Grab the rope!” Mission gives direction, not just warning.

Transition

But the mission does not end when someone is saved — it expands when believers live differently together.

Point 4 — A Church on a Mission Lives as a Mission Community

Acts 2:42–47

“They devoted themselves…” (Acts 2:42)

Mission produces a distinct people with a distinct life.

Their shared life strengthened their shared witness.

Devoted to Teaching

“All Scripture is God-breathed and is useful for teaching…” (2 Timothy 3:16)

Mission requires truth-rooted disciples.

Devoted to Fellowship

“Let us consider how we may spur one another on toward love and good deeds, not giving up meeting together…” (Hebrews 10:24–25)

Mission needs spiritual family, not isolated believers.

Devoted to the Lord’s Supper

“Do this in remembrance of me.” (Luke 22:19)

“For whenever you eat this bread and drink this cup, you proclaim the Lord’s death until he comes.” (1 Corinthians 11:26)

Even communion is mission — it proclaims Christ.

Devoted to Prayer

“Devote yourselves to prayer, being watchful and thankful.” (Colossians 4:2)

“Pray continually.” (1 Thessalonians 5:17)

Mission advances through prayer dependence.

The Missional Impact

“Enjoying the favor of all the people. And the Lord added to their number daily…” (Acts 2:47)

Supporting Scripture

“I planted the seed, Apollos watered it, but God has been making it grow.” (1 Corinthians 3:6)

Mission faithfulness — God brings growth.

Illustration

A flowing river stays fresh because it keeps moving. A stagnant pond turns sour because it stops flowing. Mission churches stay alive because they stay outward.

Closing — The Mission Is Still Ours

Acts 2 is not just the birth of the church — it is the pattern of a mission church:

Spirit-empowered Gospel-proclaiming Response-inviting Community-forming God-growing

“As the Father has sent me, I am sending you.” (John 20:21)

The mission did not end in Acts — it continues through us.

Invitation — Step Into the Mission

The Acts 2 response is still the mission entry:

Hear the gospel — Romans 10:17 Believe in Christ — John 3:16 Repent — Acts 3:19 Be baptized — Acts 2:38 Be added to His people — Acts 2:41 Live on His mission — Matthew 28:19–20

“The promise is for you… and for all who are far off.” (Acts 2:39)

The mission is still calling. And today is a good day to answer.
