As, then, the permission of evil finds a satisfactory explanation in man’s probationary state, and in God’s love, as the final cause of the creation, so also the physical evils and sufferings to which the free being is liable are fully accounted for on that principle. This is the key of the enigma of their existence. None of the sufferings of the free being, on either side of the grave, are unprofitable and without a motive. They all serve, either in this preparatory state of earthly existence, for probation, for discipline, or for confirmation, or else, after it, for the perfect healing of the soul, and its purification from all the remaining dross and taints of earth.[34] Scarcely ever can the diseased matter be got rid of and expelled from the organic body with out a struggle, and very seldom without pain. Gold is purified by the fire, and pain is the fiery purification of the body. This belief is one which ought least of all to have been called into question, inasmuch as it is only consonant to the simple feelings of human nature. For otherwise, how narrowly must the hopes of the future be confined, if nothing that is unclean shall enter into heaven--the Holy of Holies--the immediate presence of the pure and holy God! It is not, however, my intention to make this consolatory and blessed hope of a loving and longing heart the topic of dispute, especially since it lies altogether beyond my present limits. I will only allude to the words of the Savior, “In my Father’s house are many mansions.” By the “Father’s house” we must, it is clear, understand the future world. On other side, therefore, of the grave, as well as on this, many divisions, many degrees, and many different states, and also manifold transitions, are not merely conceivable and possible, but must of necessity be assumed as actually existent, even though we can not be too cautious in avoiding all hasty decisions as to what is going on in this hidden world. Only we must ever remember that any absolute line of demarcation which on one side has nothing but white, while all that lies on the other is black, is very rarely the line of truth. And this principle holds good, it is plain, in every relation and every possible application. For such a trenchant line of sharp and unmitigated contrast between black and white is even one of those intellectual deceptions connatural to man, which disposes him too hastily to transfer to all without him the limited form of his own finite intellect. All the pains, therefore, and all the sufferings of the creature, whether on this or the other side of the grave, serve either to exercise and strengthen, or to heal and purify, the yet imperfect being, with the single exception of that bitterest of all agonies--the pain of being left eternally to ourselves. But even here, although there is no hope of a salutary effect, a species of converse propriety seems to hold.
