change the world......what about you! An inspiring number of biographical accounts from some of history's greatest missionaries like David Livingstone who answered God's challenge to impact the world. Taking the message of Christ and salvation to the unexplored lands of those who had never heard the truth, he was among the faithful men and women who risked death, disease and poverty so others might know and receive Jesus as Savior. These examples remind Christians that greatness and success is to love God and love others selflessly like He has done for us. Here is a bold presentation of how faith, obedience, and love conquered isolation and fear. The accounts of these 23 obedient servants to Christ exemplify a decision to live for God and not ourselves.
