Introduction

Acts 2 is where everything changes.

The waiting of Acts 1 turns into movement.
The promise becomes reality.
The Church is born.

What began with Jesus now continues through His people—empowered by the Holy Spirit.

The Spirit Arrives in Power (Acts 2:1–4)

On the Day of Pentecost, the believers were gathered together in unity.

Then suddenly—everything changed.

They heard a sound like a mighty rushing wind filling the house.

Then they saw what looked like tongues of fire resting on each person—one flame, now divided among many.

This symbolized something powerful:

• God’s presence had come
• and it now rested on every believer

Then came the third sign:

They began speaking in other languages.

These were not random sounds—they were real, known languages.

The Spirit enabled them to speak so others could understand.

This moment marked something unique in history:

The arrival of the Spirit and the beginning of the Church age.

A Multinational Crowd Hears the Gospel (Acts 2:5–13)

Jerusalem was filled with Jewish pilgrims from all over the world.

When they heard the noise, they came running.

And what they heard stunned them:

People from Galilee speaking in their own native languages.

Luke lists regions from across the known world—showing the global scope of this moment.

The miracle wasn’t the message.

The message was the same.

The miracle was the delivery—many languages, one truth.

The reactions were mixed:

• some were amazed
• others were confused
• some mocked and said they were drunk

Whenever God moves, there will always be different responses.

Peter Explains Pentecost (Acts 2:14–21)

Peter stood up—bold, clear, and Spirit-filled.

This is the same Peter who had denied Jesus.

Now he is proclaiming Him.

He immediately addressed the accusation:

“We’re not drunk.”

Then he pointed to Scripture.

This was the fulfillment of Joel’s prophecy:

God would pour out His Spirit on all people.

Pentecost marked the beginning of that promise.

And Peter made the message clear:

Everyone who calls on the name of the Lord will be saved.

---

The Gospel Proclaimed: Jesus Crucified and Risen (Acts 2:22–36)

Peter then moved to the heart of the message:

Jesus.

He reminded them:

• Jesus was publicly validated by miracles
• His death was part of God’s plan
• they were responsible for rejecting Him

Then came the turning point:

God raised Him from the dead.

Death could not hold Him.

Peter supported this with Scripture (Psalm 16), showing that even David pointed to the resurrection.

Then he declared:

• Jesus is risen
• Jesus is exalted
• Jesus has sent the Spirit

And he ended with a powerful conclusion:

This Jesus… is both Lord and Messiah.

---

A Convicted Crowd and a Clear Call (Acts 2:37–41)

The message hit its mark.

The people were cut to the heart.

They asked:

“What should we do?”

Peter’s response was simple and direct:

• repent
• be baptized
• receive the Holy Spirit

This promise was not limited—it was for:

• them
• their children
• all who would come later

That day, about 3,000 people believed and were baptized.

The Church was born.

---

A Picture of the Early Church (Acts 2:42–47)

Luke now shows what this new community looked like.

They were devoted to:

• the apostles’ teaching
• fellowship
• shared meals (including the Lord’s Supper)
• prayer

Their lives reflected the Spirit’s work:

• awe and reverence
• generosity and sharing
• daily worship and connection
• joy and unity

They met in the temple and in homes.

Their faith was both public and personal.

And the result?

The Lord added to their number daily.

God built His church.

---

Conclusion

Acts 2 is the launch of the Church.

• The Spirit comes
• The gospel is preached
• People respond
• A community is formed

This is how God still works today.

Through His Spirit.
Through His Word.
Through His people.
