At least three thousand miracles happened at the festival of Pentecost as recorded in Acts 2. Three thousand people put their faith in Jesus Christ. Each of those miracles involved three people: an apostle who preached in an intelligible language; a festival-goer who heard the gospel message in his or her own language; and the Holy Spirit, who produced faith. As the apostle and the festival-goer come together through the work of the Holy Spirit, we see the mission of God and his church. Pentecost especially is about those three-person missional miracles.
