The Holy Spirit Comes

2 On the day of Pentecost^[a] all the believers were meeting together in one place. ² Suddenly, there was a sound from heaven like the roaring of a mighty windstorm, and it filled the house where they were sitting. ³ Then, what looked like flames or tongues of fire appeared and settled on each of them.
