After working for Barings, the merchant bank, for ten years, he committed himself to full-time preaching and became one of the most effective Christian evangelists in post-World War II Britain, especially among young people.
His understanding of the Christian life underwent a radical change in 1947 following a conference that he had arranged to which he invited members of the East African Revival Movement.
He was very much influenced by their strong emphasis on a personal implementation of the basics of the Christian faith, in particular the healing powers of openness and repentance.
He was also involved for more than forty years in organising Christian holiday conferences for family groups at Abergele, Clevedon and Southwold in the United Kingdom.
