Guarding the Gospel | Acts 15

Summary

Acts 15 records a pivotal moment in the life of the early church as believers wrestled with an essential question: What is required for salvation? Rather than adding requirements to the gospel, the apostles affirmed that salvation is by grace through faith in Jesus alone. As they sought God's wisdom together through Scripture, testimony, and the Spirit's leading, the church preserved both the truth of the gospel and the unity of the body.

Key Takeaways

• The Debate: Guard the gospel (Acts 15:1-5): The central question was whether Gentiles had to become Jewish before they could be saved. The apostles rejected every attempt to add human effort to the gospel. Salvation is by grace alone through faith alone in Christ alone (Ephesians 2:8-9).
• The Deliberation: Seek truth together (Acts 15:6-21): Peter, Paul, Barnabas, and James considered God's work, the testimony of Scripture, and the guidance of the Holy Spirit before reaching a conclusion. The early church models humility, careful reasoning, and submission to God's Word rather than personal opinion or cultural pressure.
  • *How to think theologically: *
    • Do not do theology alone. Start with humility and ask questions of godly leaders and mentors.
      
    • Reason well. Truth is not subjective, relative, or a social construct. It is objective and rooted in the character of God (John 14:6).
      
    • Learn from history and experience. Fight against recency bias, learning from the past by reading often, wisely, and widely.
      
    • Filter all claims through the truth of God's Word. Scripture is our final authority, protecting us from being "tossed to and fro by every wind of doctrine" (Ephesians 4:14; Colossians 2:8).
• The Decision: Protect both truth and unity (Acts 15:22-35): The Jerusalem church communicated its decision clearly and lovingly, strengthening believers while preserving fellowship between Jewish and Gentile followers of Jesus. Believers were encouraged to willingly limit their freedoms for the sake of unity and the advancement of the gospel.

Discussion Questions

• The early church approached disagreement with humility, Scripture, and trusted leaders. How does that challenge the way you typically respond to difficult theological or cultural questions?
• The apostles protected both the truth of the gospel and the unity of the church. Which of those comes more naturally to you? Which is more difficult?
• The sermon reminded us that God's Word—not culture or personal preference—is our authority. Is there an area of your life where you need to submit more fully to what Scripture teaches?
• What is one step of obedience you want to take this week because of what you heard from Acts 15?
