Today, I am reading and commenting on Acts 1-3.
I have often tried to picture what happened on that day of Pentecost described here from the perspective of those outside of the house where the believers were meeting. Sometimes I imagine that the people were drawn by the 120 different believers speaking loudly at the same time. However, currently I believe that people were drawn to the area by the sound of violent wind which Luke describes. I think people gathered expecting to find destroyed buildings, and perhaps people in need of rescue. When they got there they bewildered by what they heard: they heard a bunch of people speaking in their native tongue (these were people from all over the world who spoke different languages in their homes). Until recently I always assumed that different ones of the believers were speaking in different languages. Recently someone pointed out to me that the wording suggests that each of the listeners heard each of the believers speaking in their native tongue. I was unsure of it at the time, but as I read the passage today I believe that he was correct. It seems to me that the disciples were speaking in their native tongue (my understanding is that would have been Aramaic). So, from this perspective, the believers who were sharing the Gospel were completely unaware that they were speaking in anything other than their native language. The Spirit had not caused them to speak any differently than they normally did, it was those hearing them whom the Spirit changed. Which gives yet another reason to speak the Gospel to those around us, the Spirit changes those who hear the word of God.
I use the daily Bible reading schedule from “The Bible.net” for my daily Bible reading.
