B. B. Warfield lived at a time when many people—even those who considered themselves Christians—were questioning the authority of God's Word. For centuries most people in Europe and North America had taken for granted that the Bible was the word of God, but in Warfield's lifetime they were wondering whether it could still be trusted. Warfield was confident that the Bible could be trusted, and as a professor of theology at Princeton Seminary, he devoted his life to teaching and writing about its authority and other important issues of theology. In this biography, Simonetta Carr introduces children to one of America's greatest Reformed theologians whose timeless writings address challenges to the truths of God's Word today.
