Roy Hession, a successful evangelist in England, knew he had lost the power of the Spirit in his life – a terrible feeling as he led his evangelistic campaigns. In 1947, Hession met leaders of the East African Church which was then experiencing a sweeping revival, and recognized his deep personal need. It was like starting the Christian life over as he came humbly to the Cross. The principles which the Lord taught him were first published in 1950 as The Calvary Road and are now available in over 70 languages.
