The greatest revival in scripture was Pentecost, which happened fifty days after Jesus rose from the dead. On the day of Pentecost, the Holy Spirit poured out on Jesus’ disciples, Peter preached a powerful sermon, and 3,000 people repented of their sins and were baptized. This remarkable event started the early New Testament church with a diverse group rooted together by one major thing: their understanding of the Gospel and devotion to the risen Jesus.
