The History and Message of the Keswick Convention

From the Preface:
Every year, during the month of July, thousands of Christians from all parts of the world gather for a Convention for the deepening of the spiritual life, lasting one week, in the little town of Keswick, which nestles at the foot of Skiddaw mountain and beside beautiful Lake Derwentwater, in the Lake District of northern England, a region famous by association with the Lake poets – Wordsworth, Coleridge, and Southey – and for picturesque and fascinating scenery unsurpassed in all England, if not in all Europe.
Since 1875, when the first of these Conventions was held, the influence of what is taught there has been increasingly felt in the Christian world, until Keswick teaching has come to be regarded as one of the most potent spiritual forces in recent Church history. The ’Keswick movement’ has become historic…. Here, then, we have the teaching of Keswick, one of the most interesting religious phenomena of our time.
