Iain Murray has already written on a number of Christians he specially admires. A few of them return to these pages, but with special reference to their thought- George Whitefield on Christian unity, for example. Most space, however, is given to little-known figures, including Robert Kalley and William Hewitson who shared in ‘the greatest happening in modern missions’, and to Charles and Mary Colcock Jones who took much-loved slaves with them to heaven.
