A Sweet Flame is a sweet book, that introduces readers to the piety of Jonathan Edwards (1703-1758) through his own letters. Dr. Haykin’s biographical sketch of Edwards captures the importance the New England minister placed on Scripture, family piety, and the church’s reliance upon God. The remainder of the book presents 26 selections from various letters written by Edwards, two written by family members at his death, and an appendix drawing upon Edwards’s last will and the inventor of his estate.
