Pentecost was a divine missionary strategy — God gathered diaspora Jews to Jerusalem so the gospel could radiate back to every nation

Mike argues that the feast calendar was God's providential mechanism: Passover and Pentecost brought Jews from every nation to Jerusalem. At Passover they could witness the crucifixion and resurrection testimonies. At Pentecost they hear the gospel and witness the Spirit's coming, then carry it home. This is God's missionary brilliance — taking the gospel to the Jew first and from there to all nations.
