An inspiring look at how God changed a tribe, and then an entire region of indigenous people, from the inside out. Olson, the missionary in this autobiographical work, shares the details of his calling, his background, and the love God gave him for the native people. Olson was burdened to share his faith with the Motilones without stripping them of their cultural identity and "Americanizing" them. It seems he was successful where other missionaries had failed.
