When the day of Pentecost came, they were all together in one place. 2 Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. 3 They saw what seemed to be tongues of fire that separated and came to rest on each of them. 4 All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.
5 Now there were staying in Jerusalem God-fearing Jews from every nation under heaven. 6 When they heard this sound, a crowd came together in bewilderment, because each one heard them speaking in his own language. 7 Utterly amazed, they asked: “Are not all these men who are speaking Galileans? 8 Then how is it that each of us hears them in his own native language? 9 Parthians, Medes and Elamites; residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, 10 Phrygia and Pamphylia, Egypt and the parts of Libya near Cyrene; visitors from Rome 11 (both Jews and converts to Judaism); Cretans and Arabs—we hear them declaring the wonders of God in our own tongues!” 12 Amazed and perplexed, they asked one another, “What does this mean?”
Pastor Kessler had an interesting sermon this morning on this, delivering the message of Pentecost without becoming Pentecostal in the processs.
What did that mean? God was reaching out to people in their mother tongues. That is still a work in progress, as we deliver the Gospel two millennia on in settings and media that Peter and company couldn't even dream of. Such translation can often be in the form of good heurmaneutics to bring the message to a modern listener, but the Holy Spirit is still the one in charge.
