What happensPermalink
On Pentecost, the Holy Spirit fills the disciples as promised. They begin witnessing to God’s wonders in many of the languages of the Roman Empire to the Jews who had gathered in Jerusalem for the feast. Peter preaches the first Christian sermon, and three thousand people are saved.
Why it mattersPermalink
The coming of the Holy Spirit fulfills Joel’s prophecy (quoted by Peter) and Jesus’s promise. As Jesus charged them, the disciples begin their witness in Jerusalem. Peter’s sermon quotes many Old Testament scriptures to identify Jesus as the Messiah.
