What does the Bible say about the miracle of Pentecost?

The miracle of Pentecost, as described in Acts 2, illustrates how the Holy Spirit empowered the apostles to proclaim the gospel in languages they had never learned. This was a fulfillment of the prophecy of Joel, demonstrating God's commitment to save His people by revealing the gospel to them in a way they could understand. As a result, approximately 3,000 souls were added to the church on that day, highlighting that the true miracle lies in the transforming power of the gospel that brings about faith in Christ.
