This is a recording from 1972 of the testimony of Bruce Olsen, missionary to Colombia's Motilone Indians. At 19 years old, Olsen left his university studies to go to Colombia to reach the Motilone, a tribe that was hostile and violent toward outsiders. While Olsen was reaching out to the tribe, one of the members shot him in the leg with an arrow. Surprisingly, they did not kill him but nursed him back to health. Olsen spent the rest of his career reaching this tribe with the Gospel of Jesus Christ.
