"Loiter not on the banks of the muddy stream; wait for the pure cool water from the spring," was the Dani adage spoken in hushed expectant voices to their children and often flung at the airplanes flying high overhead. In 1960, we joined our colleagues serving the Dani tribespeople hidden in the interior mountainous area of Papua, Indonesia. We had entered the world of a grieving people whose myths declared they had lost their opportunity to enjoy eternal life. The story of their acceptance of us and our message, their dramatic conversion experience, their joy in planting dynamic congregations in their area and among other unreached tribes, and their excitement at being able to read God's Word in their own language, you will read in the pages of this book. They found and currently enjoy drinking of the "pure cool water from the Spring." Author, David L. Scovill, with his wife, Esther, have served in Indonesia for nearly half a century with UFM International, now CrossWorld. The amazing Western Dani tribe in Papua has been the focus of their ministry and home to their two children. Esther, daughter of missionary parents, grew up in Cuba; Dave on a farm in Minnesota. Both graduated from Prairie Bible College, then added missionary medicine and linguistics to their preparation. Dave completed his post graduate work at the School of World Missions and Columbia International University. Their backgrounds, training and combined skills prepared them well for their many roles: Dave as pioneer and missionary linguist, church-planter and teacher, Bible translator and mission administrator; Esther as homemaker and teacher, medical worker and bookkeeper. During retirement, they make their home near Columbia, South Carolina.
