John Keith-Falconer is recognized as a "Master Missionary" due to the unique circumstances of his dedication and the influence he had. Born into a noble family with brilliant academic talents, and being wealthy, a lover of sports, and a champion cyclist, he gave up a promising career in England to start a mission among the Muslims of Southern Arabia. Although his life there was short and his accomplishments were few, the work he began continues, and his character and example have inspired many. This account, written by someone who has followed in his footsteps, might be more effective in encouraging new missionaries than biographies filled with stories of great success.
