A hymn is a child both of its author and of the time in which he lived. A proper knowledge of the writer and the age that gave it birth will enhance our understanding both of the hymn and of the spiritual movement it represents. No other branches of literature furnish a more illuminating index to the inner life of Christendom than the great lyrics of the Church. Henry Ward Beecher said truly: “He who knows the way that hymns flowed, knows where the blood of true piety ran, and can trace its veins and arteries to its very heart.”
