Short meditations and letters written by one who was called in the furnace of affliction. There in seclusion from the outer world, he was led by the Spirit through the Word into a knowledge of the "deep things of God." Some of the contents are: The Boundless Love of God; Christ Must be Everything; Grace and its Abuse; Sonship and Its Privileges; The Father's Chastening Rod; Our Education for Eternity; The Lord's Care of His People; Crucified With Christ; Holy Living; the Deceit of the Human Heart; Divine Searchings and Self-Abasement; How our Marah's are Made Sweet.
