The small group of Christian students active in Cambridge in the 1820s hardly expected their work to have remarkable effects. Yet out of ‘the Jesus Lane lot’, as they were nicknamed, grew the Cambridge Inter-Collegiate Christian Union (CICCU), whose influence has been world-wide. Oliver Barclay and Bob Horn tell the story of the CICCU to mark its 125th anniversary. The life and times of this Christian Union are interwoven with evangelical Christianity and some of its most significant figures. The story points above all to God, who gives the vision and the strength to pursue it.
