is only the perceived privation of what you know to be good, and which you know to be good because of the very presence of limitation, hindrance, and imperfection. +The relation of evil and pain.+--But to most minds evil is almost synonymous with pain, at any rate in our experience it is associated with pain. When men begin questioning the goodness of God because of the evil of the world, they usually mean the pain of the world. Perhaps their thought about sin is to some extent an exception; sin and pain are not necessarily immediately associated in the theological mind. But what is pain? Properly speaking it is not in itself evil, but rather the evidence of evil, and also in a different way the evidence of good. Pain is life asserting itself against death, the higher struggling with the lower, the true with the false, the real with the unreal. When a baby cries for food he does so in unconscious obedience to the law of life; a stone does not cry for food. When a strong man suffers in the grip of a fell disease, the life within him is fighting for expression against something that seems to be extinguishing it. The suffering is caused by the effort of the life to retain its hold on the form, and yet if the disease succeeds in breaking the form it has only released the life to find expression in some higher form. When a guilty man suffers the tortures of remorse, it means that the truth within him is declaring itself against the falsehood, although it does not follow that it will immediately conquer. This is what pain is: it is life pressing upon death, and death resisting life. If a traveller falls asleep in the snow, or a sailor is nearly drowned, the process of recovery is always painful because the returning life has to overcome death. Carry the same principle through the whole range of human experience, physical, mental, and moral, and it will indicate the real significance of all the pain which has ever been endured or ever will be endured by mankind.
