"One very important feature of the world we live in is its moral symbolism. The world is full of most suggestive symbols and emblems of moral good and evil. There are all beautiful and glorious things, to stand as types of goodness, truth, and righteousness; there are all loathsome, malignant, and hideous things, to serve as the types of folly and wickedness. Was it merely an accident that the dove was fitted to become the emblem of purity and of the Holy Spirit? the lamb, to be the emblem of gentleness, of Christ the gentle Sufferer, and of his suffering people? the ant, to be the type of prudent industry? the horse, of spirit and daring? and the lion, of strength and regal state? Was it only an accident that prepared cruel beasts and disgusting, poisonous reptiles as the types of evil passions and sins--that made the venom of the viper, the cunning of the fox, the blood-thirstiness of the wolf, the folly of the ape, and the filth of the swine, symbols of foul, subtle, malignant sin and folly? Nature is full of these emblems. The palm tree with its crown of glory, the cedar of Lebanon, the fading flower and withering grass, the early dew and the morning mist, the thorn hidden among the leaves of the fragrant rose, poisons sweet to the taste, and medicines bitter as gall,--how all these natural things preach to men sermons concerning spiritual verities! There is no virtue or grace which is not commended to man by its image of beauty in the animal tribes; there is no vice against which men are not warned by its loathsome, disgusting form shadowed out in the instinctive baseness of irresponsible brutes. "Thus we find earth, air, and sky to be full of silent voices proclaiming in the ears of man that which he most of all needs to remember. These types and symbols of virtue and vice are specially needed by fallen beings. They seem fitted for beings whose spiritual eyes are blinded and all their spiritual senses blunted--beings with whom there is no longer 'open vision' of spiritual realities. These pictures of evil are most impressive to men who see in them the reflection of their own base passions. How the fetid goat and the swine wallowing in the mire speak to the lecherous man and the drunkard! In a world of sinless beings these mimic vices would seem rather to mar God's handiwork. "Set the human race, fallen as it is, in a world where the patience of daily industrious toil would not be needed, and the race would rot with putrid, festering vice. Remove all danger, and men would forget and deny that the Creator holds them responsible. Let no evil consequences follow evil-doing, and men would cease to make a distinction between right and wrong. Take away death, and they would deny the existence of a spiritual world. But in this world God has hedged men around with checks and penalties and painful discipline, such as are of use only in dealing with sinners.
