In a college room at Cambridge University in 1920 twenty four young men, who had heard God's call to the mission field, knew they wanted to keep in touch after they had gone their separate, God-appointed ways. They had formed a close bond during the previous years at Cambridge as they prayed together, studied their Bibles together and shared their faith in Jesus Christ with fellow students, calling themselves the Cambridge University Missionary Band (C.U.M.B.). In the next seventy years these men would be involved in worldwide movements of the Holy Spirit. This book contains the letters of one member of the Band, Norman Percy Grubb. Although not at the inaugural meeting because he was already in the Belgian Congo with C.T. Studd, Norman was one in heart with his brothers. They shared intimately with each other-their successes, sorrows, joys and failures. In these letters spanning the years 1922 thru 1989, you will find men of faith; men with a heart and passion to share their Saviour; ordinary men; extraordinary men; men involved in many great and worldwide movements of the Spirit and simple men with a lifelong love for their Lord, their families and each other. You will find yourself caught up in history and inspired as you share in the lives of these "called" men of God.
