Dr. Gaius Davies introduces us to Martin Luther, John Bunyan, William Cowper, Lord Shaftesbury, Gerard Manly Hopkins, Christina Rossetti, Amy Carmichael, J.B. Phillips, C.S. Lewis, Martyn Lloyd Jones and Frances Ridley Havergal.

After a brief biographical introduction to each person, he shows us how he or she all had their particular trial, and how grace operated in each of them. He is not afraid to show how anxiety, guilt, depression and doubt can be present in the finest of Christian lives, but also goes on to show how divine grace can transform human weakness.
