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, howver, 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.
There is much new research in these pages, and reminders of how much is missed by those who fail to read of the work of God in history. Christians who know what Christ did 'yesterday' are energized to trust and serve him today.
