Here is the story of the first missionary from South Korea to the unreached tribesmen of the vast Amazon Jungle. Trudging the dark, sometimes flooded trails of the malaria infested forests of western Brazil, he faced alone the terrifying prospect of becoming disoriented and lost in the unmarked darkness, falling prey to wild animals, savage Indians, or succumbing to malaria or dengue fever transmitted by ever-present blood-succking insects. Motivated by a clear calling from God and directed by divine guidance, he overcame obstacles of nature and of men who opposed his mission to bring to primitive savages a place in the twenty-first century as well as the eternal hope of heaven. Loved by the Indians he reached, and hated by the anthropologists who opposed his efforts, he and his wife Jae Sun invested forty years of their lives in obscurity. While some may consider that a waste, Sung Joon Kim would say that being in the center of God's will is of itself a great reward.
