Major W. Ian Thomas was born in London, England of middle class parents and was converted at the age of twelve in a Boy's Camp. With the intention of becoming a missionary in Africa, he studied medicine at London University for two years, where as a student of nineteen, in deep discouragement about his Christian life, he discovered the life-transforming secret of the indwelling life of the risen, living Lord Jesus Christ in the life of the believer. This discovery precipitated him almost immediately into an evangelistic and Bible teaching ministry which has spread around the world.
