Season 3: The Gospel Goes Out

Introduction

As the gospel spread, new questions emerged.

Many Gentiles were coming to faith in Jesus Christ. Churches were growing in cities far beyond Jerusalem. People from different cultures, traditions, and backgrounds were becoming followers of Christ.

This growth created an important challenge.

Did Gentile believers need to follow all Jewish customs in order to become Christians?

The answer would shape the future of the Church.

Acts 15–18 tells the story of how the early Church wrestled with difficult questions, sought God’s guidance, and discovered that salvation comes through God’s grace rather than human achievement.

These chapters also show the gospel continuing to cross cultural, geographic, and social boundaries as new churches were established throughout the Roman world.

The mission continued because God’s grace was greater than human divisions.

Scripture References

Acts 15–18 (NASB)

Key Verse

“But we believe that we are saved through the grace of the Lord Jesus, in the same way as they also are.” — Acts 15:11 (NASB)

Historical Background

The Church was experiencing remarkable growth among Gentiles.

Some Jewish believers argued that Gentiles should follow certain Jewish requirements before being fully accepted into the Christian community.

The issue was serious enough that church leaders gathered in Jerusalem to seek God’s guidance.

This meeting, often called the Jerusalem Council, became one of the most important moments in the history of the early Church.

The decision affirmed that salvation comes through faith in Jesus Christ and that Gentiles were fully welcomed into God’s family.

Following the council, missionary efforts expanded even further.

GROW Framework

Grounded in Scripture

The Jerusalem Council

(Acts 15:1–21)

Church leaders gathered to discuss a difficult question.

How should Gentile believers be welcomed into the Church?

Peter reminded the council that God had already given the Holy Spirit to Gentile believers.

Paul and Barnabas shared stories of God’s work among the nations.

James helped guide the discussion toward unity.

Together they recognized that salvation comes through God’s grace rather than human traditions.

The Church chose unity over division.

Encouraging the Churches

(Acts 15:22–35)

The council sent a letter to Gentile believers explaining its decision.

The message brought encouragement and reassurance.

The leaders sought to strengthen the churches rather than burden them.

Healthy leadership helps people grow in faith.

A New Missionary Journey Begins

(Acts 15:36–41)

Paul and Barnabas eventually disagreed about ministry plans.

Even faithful believers sometimes experience conflict.

Although they separated, God’s mission continued.

Two ministry teams now carried the gospel to different regions.

God continued working through imperfect people.

The Gospel Reaches New Regions

(Acts 16)

Paul traveled with Silas and later Timothy.

The Holy Spirit guided them toward Macedonia.

A woman named Lydia became one of the first recorded converts in Europe.

A jailer and his family also came to faith after witnessing God’s power.

The gospel crossed geographic and cultural boundaries once again.

Ministry in Thessalonica and Berea

(Acts 17:1–15)

Some people welcomed the message.

Others resisted it.

The believers in Berea were commended because they carefully studied the Scriptures to confirm what they heard.

Faith grows through both trust and understanding.

Paul in Athens

(Acts 17:16–34)

Athens was a center of philosophy and learning.

Paul spoke to people who knew little about the Scriptures.

Instead of beginning with Jewish history, he connected the gospel to their culture and experiences.

Paul demonstrated that the message never changes, but the way we communicate it may vary.

Ministry in Corinth

(Acts 18)

Paul continued sharing the gospel and establishing churches.

God encouraged him to remain faithful despite challenges.

The Church continued growing as believers learned, worshiped, and served together.

Reasons We Believe

Salvation Comes Through Grace

The Jerusalem Council affirmed that people are saved by God’s grace through faith in Jesus Christ.

No one earns salvation through human effort.

Unity Matters

The early Church worked through disagreements while remaining committed to Christ and His mission.

God calls believers to pursue unity without compromising truth.

The Gospel Is for Every Culture

Paul adapted his approach while remaining faithful to the message of Jesus.

The gospel can be shared with people from every background and culture.

God Uses Imperfect People

Paul, Barnabas, Peter, James, Lydia, Timothy, and countless others played important roles in God’s mission.

God continues working through ordinary believers today.

Obedience in Action

Acts 15–18 challenges believers to ask:

How can I help promote unity within the Church?

Do I understand that salvation is a gift of grace?

How can I share the gospel with people from different backgrounds?

Am I willing to learn from believers who see things differently?

How can I encourage others in their faith journey?

The Church grows when believers focus on Christ and extend grace to one another.

Walk It Out

Consider these questions:

Why was the Jerusalem Council so important?

What does this passage teach about grace?

How did Paul adapt his approach when speaking to different audiences?

Why is unity important for the Church?

How can believers today cross barriers to share God’s love?

Possible Responses

You may recognize opportunities to build bridges with people who are different from you.

You may gain a deeper appreciation for God’s grace.

You may identify ways to encourage unity within your church and community.

Living the Message

The Church faced difficult questions and significant changes.

Yet God’s mission continued.

The gospel crossed cultural boundaries.

New believers were welcomed.

Leaders sought wisdom.

Churches were strengthened.

Acts 15–18 reminds us that the Church grows when believers focus on Jesus Christ, extend grace to others, and remain open to the leading of the Holy Spirit.

The mission of the Church has always been bigger than any one culture, nation, or group of people.

God’s invitation is for everyone.
