Are there any examples of this same sort of "revival" in the Bible?
Excellent question! Acts 2 and 4 provide the closest NT parallel to the modern historic revivals described in this thread's videos:
"So those who welcomed his [Peter's] message were baptized, and that day
about 3,000 people were added (2:41)."
"They praised God and had the goodwill of all the people. And the Lord added to their number
daily those who were being saved (2:47)."
When they had prayed, the place where they were gathered
was shaken, and they were all filled with the Holy Spirit and spoke the Word of God with boldness (4:31)."
Peter's Pentecost sermon produces 3,000 converts and for an extended period new conversions are made daily. The energy and power of the Spirit are so palpable that their worship centers vibrate and healing miracles occur. But should the earliest phase of the church be considered a "revival" in the same sense as the First and Second Great Awakenings and the Welsh and Hebrides Revivals? That depends on how one defines "revival." I would not grant the earliest phase of conversions that same status as these later revivals because these later ones produced far more conversions over several years and the presence of the Spirit was palpable to almost everyone in whole regions over a long period of time. By contrast, the earliest church quickly suffered the backlash of sustained persecution. So I view these modern revivals as the best example of the fulfillment of Jesus' promise in John 16:7: "Very truly I tell you, the one who believes in me will also do the works that I do and, in fact,
will do greater works than these because I am going to my Father."
