With the heart of an explorer and the passion of an evangelist, David Livingstone mapped vast, unexplored areas of Africa, sharing the gospel with whomever he encountered. His stamina, perseverance, and dogged determination created the legacy of a trailblazing explorer with an undying hunger to make Christ known wherever his steps led him.

Flying soon captured Nate's (1923-1956) heart. His air-service ministry to isolated missionaries put him on a path of destiny that would ultimately end with a final airplane flight with four missionary friends to the "Palm Beach" landing strip in the jungles of Ecuador. The men's lives given that day not only opened a door to the gospel for the unreached "Aucas"; it has been said that possibly no single event of the twentieth century awakened more hearts to God's call to serve in missions.

Betty Greene coaxed her Grumman seaplane to 2,000 feet.... Suddenly, silence - total silence. The plane engine had stopped! Her passengers gasped, but Betty knew she must remain calm.

Eric's (1902-1945) refusal earlier that week to run on Sunday in the Olympic 100-meter race had stunned the world.

Years later, Eric Liddell would be tested far beyond mere physical ability as a missionary to China. His character, perseverance, and endurance are a challenging example for all who would obey the call to bring the gospel to the nations.

God would indeed answer the prayer of the fiery, red-haired woman from Scotland. For 39 years, Mary Slessor would labor in love among the unreached, often treacherous, tribes of Africa's Calabar region. Braving sickness, danger, and death on all sides, Mary became the cherished "White Ma" to entire tribes. Her faith, steadfastness, and pioneering spirit brought her beloved adopted people their first brilliant, contrasting example of the life and freedom found in Jesus Christ.
