Acts 2 records a life-changing moment: not just a personal experience, but the birth of the Church. On the day of Pentecost, the promised Holy Spirit (Acts 1:8) descended, filling ordinary people with extraordinary power. What followed was not confusion, but clarity; not fear, but boldness; not silence, but a Spirit-empowered proclamation of the gospel that led to thousands being saved. This passage answers three essential questions: What does the Spirit do when He comes? How does the gospel take root in people’s hearts? And how are we called to respond today?
