The world to come: Or, Discourses on the joys or sorrows of departed souls at death, and the glory or terror of the resurrection. To which is prefixed, An essay toward the proof of a separate state of souls after death. Wherein, after some representations of the happiness of heaven, and a preparation for it, there follows a rational and scriptural account of the punishments in hell, and a proof of their eternal duration. With a plain answer to all the most plausible objections. By I. Watts, D.D.
