Book excerpt: Before she was baptized or knew anything about Christ, young Nenilava was called by Jesus to preach and exorcise in his name. At the age of twenty, newly married to a Lutheran catechist, she heard Jesus prompting her to intervene in a case of demon possession, and from there her ministry spread like wildfire. She spent the next sixty years of her life traveling around her native Madagascar, proclaiming Jesus’ victory over sin, guilt, and evil, and bringing countless people to faith. In this book, her firsthand account of her early ministry, as told to a Malagasy pastor, appears for the first time in English. Complementing the immediacy of her narrative, former missionary in Madagascar, James B. Vigen, recounts the last thirty years of Nenilava’s life and describes the extraordinary impact of this illiterate peasant woman on African Christianity. Sarah Hinlicky Wilson concludes the book with a far-reaching exploration of demon possession, healing from illness and sin, emergent offices of ministry, and the relevance of Nenilava for Western Christianity.
