In 1910, after becoming a very popular speaker in certain circles throughout the country, George went to the All Saints' Anglican Church in Sunderland, England. There he saw people expressing the Gifts of the Spirit, particularly speaking in tongues as in Actschapter 2 in the Bible. George was at first opposed to this, but when his nephew, Edward, claimed to have received the Baptism of the Holy Spirit, and he noticed the change in his nephew, he repented of his unbelief in the All Saints' church, and subsequently, began to express such gifts himself. In the many churches, conventions and camp meetings where George and Stephen Jeffreys preached in the years after this, there were reports of many miraculous healings and other acts of God. Such healings brought George to his "foursquare" belief that Jesus is Saviour, Healer, Baptiser and Coming King. George, along with a small group of peers, became known as the Elim Evangelistic Band in Belfast and all over Ulster. This group of people brought crowds into their large tent, and later, into the Belfast hall they acquired. Out of this, George founded his first church in Belfast in 1914 followed by one in Monaghan in 1915, and the Elim Foursquare Gospel Alliance, as it is officially known, was born. Many more Elim churches were soon planted all over the United Kingdom, first of all spreading through the province of Ulster to Ballymena, Moneyslane and Portadown, then on to Leigh-on-Sea, Essex, The First Elim Church in England, and Clapham in London and in Wales at Llanelli and Dowlais. In 1925, he founded the Elim Bible College in Clapham, which moved to Nantwich, Cheshire, in 1987 and later became Regents Theological College. The college moved again in 2009 to West Malvern. George continued to lead the Elim Pentecostal Churches until 1939 when, due to differences in opinion on church leadership and the idea of British Israelism, he left Elim and went to Nottingham to found the Bible-Pattern Church Fellowship, The denomination suffered a serious decline in numbers in the later years of the 1960s and no longer exists as a separate entity, its main church, Kensington Temple, having become the central London church of the Elim Pentecostal Church. In 1962 George spoke with Reinhard Bonnke the evangelist concerning the ministry that Bonnke was about to begin in South Africa. Bonnke stumbled onto Jeffreys' home in Clapham while on vacation in London. The old evangelist invited Bonnke in for tea. Jeffreys prayed for the young 22-year-old Bonnke, passing on his "mantle".
