While the eleven apostles waited in Jerusalem, Matthias was chosen to replace the now-dead Judas. During the Jewish feast of Pentecost, the Holy Spirit came upon the apostles just as Jesus had promised. The Spirit gave these uneducated men the miraculous power to speak in languages they had never learned or spoken before (speak in tongues). Because of this, all of the crowds of Jewish pilgrims from many countries were able to hear about Jesus in their own languages. After Peter preached the first “gospel sermon,” 3,000 people were baptized. Emphasise that this was the beginning, or “birthday”, of the church.
