Pentecost was the busiest day of the year in Jerusalem. And Jesus’ followers were gathered in prayer. They were not separated from society but smack-dab in the center of it. Once God had them where he needed them, the Holy Spirit came upon them suddenly; first as wind and then as individual tongues of fire (Acts 2:4 KJV). Individual flames hovered over each person and they began to speak with other tongues as the Spirit gave them utterance.
People from all over the world heard the wonderful works of God. Whatever could this miracle mean? It means at least this much: God loves the nations. He has a red-hot passion to reach every people group on the planet. He loves everybody. And that includes you, my friend.
