The book of Acts shows that following Jesus is both joyful and challenging, filled with revival, miracles, and unity, yet also marked by persecution, conflict, and disagreement. In Acts 15–16, we see the Church wrestling with theological debates—whether Gentiles needed to follow Jewish customs—and personal disputes, such as Paul and Barnabas parting ways over John Mark. Through it all, God kept purifying the Church’s understanding of the gospel. These stories remind us to stay humble, teachable, and committed to Christ’s mission, even when disagreements arise.
