one of the main leaders of the Welsh Methodist revival in the 18th century, along with Daniel Rowland and William Williams Pantycelyn. He underwent a religious conversion in May 1735 after listening to a sermon by the Rev. Pryce Davies, the Sunday before Easter, in the parish church on the necessity of partaking of Holy Communion. This led to several weeks of self-examination. This reached a climax at Communion on Whit Sunday, May 1735, following the sermon. After what is described as answering the devil's accusations, he received Communion, and came to the conviction that he had received mercy through the blood of Christ. This resulted in a sense of great joy.
