This book brings into one illustrated volume eleven great lives, all with an experience of personal conversion to God. Composer Mendelssohn, food industrialist Henry Heinz, novelist Daniel Defoe, and some of the most celebrated scientists of all time including Michael Faraday and Lord Kelvin are among the examples of leading people whose lives were changed by a sight of real Christianity. Also very suitable as a gift to unconverted friends, and to enrich sermons and Bible Class messages.
