In 1905, Roberts began studying for the ministry at Newcastle Emlyn. Attendance at a service held by evangelist Seth Joshua in Blaenanerch, Cardigan led to an experience that formed Roberts' belief in the "Baptism of the Spirit". In October of that year, Roberts began speaking at a series of small meetings. These appearances led to his involvement in the Revival. He was soon attracting congregations numbering thousands. Within two weeks the Welsh Revival was national news and before long, Evan Roberts and his brother Dan and his best friend Sidney Evans were travelling the country conducting Revival Meetings.
