It is no anachronism to republish Joseph Alleine's book, A Sure Guide to Heaven, from a day when men were more deeply conscious of the world to come. When the spiritual history of the Western World in the 20th century is written, it may well be seen as the epoch of spiritual sloth and slumber. Eternal realities seemed vaguely-defined and far-removed from daily life, and conformity to the world took the form of carelessness and neglect of spiritual issues. Written by a servant of God whose preaching and writing were used to alarm and awaken many to the concerns of life and death.
