Acts 2 is the chapter where the early church blows up. Boatloads of Jews from all over have come to Jerusalem to celebrate the holiday of Shavuot, known in Greek as Pentecost. The Holy Spirit miraculously grants the disciples the ability to speak and comprehend various languages, in a kind of reverse Babel, and Peter preaches a gospel message to the crowds that results in thousands repenting and getting baptized. In the previous chapter, the disciples had been biding their time, waiting for the gift of the Holy Spirit that Jesus had promised them. But here God starts making waves, and he won’t let up until it gets the disciples kicked out of Jerusalem. But I’m getting ahead of myself.
