When Pentecost Day arrived, they were all together in one place. 2 Suddenly a sound from heaven like the howling of a fierce wind filled the entire house where they were sitting. 3 They saw what seemed to be individual flames of fire alighting on each one of them. 4 They were all filled with the Holy Spirit and began to speak in other languages as the Spirit enabled them to speak. 5 There were pious Jews from every nation under heaven living in Jerusalem. 6 When they heard this sound, a crowd gathered. They were mystified because everyone heard them speaking in their native languages. 7 They were surprised and amazed, saying, “Look, aren’t all the people who are speaking Galileans, every one of them? 8 How then can each of us hear them speaking in our native language? 9 Parthians, Medes, and Elamites; as well as residents of Mesopotamia, Judea, and Cappadocia, Pontus and Asia, 10 Phrygia and Pamphylia, Egypt and the regions of Libya bordering Cyrene; and visitors from Rome (both Jews and converts to Judaism), 11 Cretans and Arabs—we hear them declaring the mighty works of God in our own languages!” 12 They were all surprised and bewildered. Some asked each other, “What does this mean?” 13 Others jeered at them, saying, “They’re full of new wine!” (Common English Bible)
Yet Peter does not write them off. He goes on from this passage to preach an incredible sermon—incredible because if you knew him at all during the Gospels, you wouldn’t recognize the theological depth of what Peter is saying in comparison to his bumbling blockheadedness back when he was following Jesus around everywhere.
