These 18 sermons on the central themes of the Gospel were first published in 1961, with an introductory essay by Dr. John Marsh, Principal of Mansfield College, Oxford. 'Most of these sermons were in fact preached to inmates of Basel Prison, where the great theologian is a visitor. Wisdom, honesty, consideration and reverence shine through these pages' (Guardian). 'Here is evangelical preaching which has the surge and onward movement of a symphony. It should be read aloud, so that the tremendous force of the Scripture words, and the passion of the preacher, may be truly felt. This is power-this is grace' (Life and Work, the Record of the Church of Scotland). ‘Has won universal approval for its simplicity, humanity and devotion' (T. H. L. Parker in SPCK View Review, 1965).
