The revival spread like wildfire, and one of the areas that was most affected was Maesteg, the hometown of George and Stephen Jeffreys.

Roberts and his workers visited the area on three separate occasions and brought more than five thousand people into the kingdom of God. On November 20, 1904, the Reverend Glasnant Jones stood before the Siloh congregation and preached a message of salvation. Prior to this date, George and Stephen had attended church on occasion. That morning, they experienced a dynamic conversion and were baptized in the Holy Spirit. Immediately afterward, they started serving the Lord at the church in any way they could. To the dismay of the Jeffreys brothers and much of Wales, the Welsh revival lasted only two years before it fell into decline.

Roberts Liardon tells us that the Welsh Revival was fading, but a group of young men in Maesteg were not willing to let go of the power of God. They didn’t believe He would birth such a sweeping revival, only to let it end so quickly. So, they formed a small prayer band and called themselves the “Children of the Revival.” On their knees, they beseeched God to send His power. In the decades to come, their prayers would be answered in ways beyond anything they had imagined. While the Welsh Revival was winding down, the Azusa Street Revival in Los Angeles, California, was moving forward at full speed. In addition to repentance, the Azusa Revival emphasized the experience of the baptism in the Holy Spirit with the evidence of speaking in tongues.

Soon, the work of the Holy Spirit that had begun in Azusa Street swept into Europe. A Norwegian pastor by the name of Thomas Ball (T. B.) Barratt sailed for the United States in 1905 to raise funds for his Methodist mission in Oslo. Though he stayed for over a year, the visit was a financial failure. As he prepared to return to Norway in Fall 1906, he heard about the Azusa Street Revival and read the first issue of their newspaper, Apostolic Faith. After corresponding with them, he attended a small meeting in New York and was baptized in the Holy Spirit.
