Music communicates in a language that is experienced more powerfully than the spoken word. John Bell joins Dom, Peter and Sue to explore the way music can powerfully shape and change not only our experience of worship, but also how we understand ourselves and God.  What do the songs we sing tell us about what we really believe and how we think we should live? John is a hymn writer, composer, lecturer and broadcaster, and an ordained minister of the Church of Scotland and member of the Iona Community.
