When young Rachel Saint (1914-1994) surrendered her life to God, she began an unimaginable journey that would span decades and radically transform a dying culture steeped in revenge. Against all odds, God would lead her to Ecuador's Waorani Indians - known as Aucas, or savages, and infamous for murder. Despite the martyrdom of five missionaries by Waorani spears, Rachel boldly persisted in following God. In one of the greatest testimonies to God's grace and power in our time, this pioneering Bible translator would live for two decades with her own brother's killers, for the joy of seeing them become brothers and sisters in Christ.
