L. B. Hartman's masterpiece, Divine Penology
Now available from Decretum Books
explores our natural discomfort with hell, and then turns to argue for its goodness and glory. Drawing not only from Scripture, the early Church Fathers, and the Puritans, but also from secular philosophy and history, the book aims not to defend the doctrine of hell, but attempts something bolder—to persuade that hell, in all its terror, is good.
Disbelieve hell, and you unscrew, unsettle, and unpin everything in Scripture. You may as well throw your Bible away at once. From "no hell" to "no God" there is but a series of steps.
—J.C. Ryle, Practical Religion
