Well, then, further, this solemn emblem stands for impurity. And we have only to consult our own hearts to feel how true it is about us all, that we dwell in a region all darkened, if not by the coarse transgressions which men consent to call sins, yet darkened more subtly and oftentimes more hopelessly by the obscuration of pure selfishness and living to myself and by myself. Wherever that comes, it is like the mists that steal up from some poisonous marsh, and shut out stars and sky, and drape the whole country in a melancholy veil. It is white but it is poisonous, it is white but it is darkness all the same. There are other kinds of sin than the sins that break the Ten Commandments; there are other kinds of sin than the sins that the world takes cognisance of. The worst poisons are the tasteless ones, and colourless gases are laden with fatal power. We may walk in a darkness that may be felt, though there be nothing in our lives that men call sin, and little there of which our consciences are as yet educated enough to be ashamed. Rent from God, man lives to himself, and so is sunk in darkness. And what shall I say about the third of the doleful triad of which this pregnant emblem is the recognised symbol all the world over? Surely, though earth be full of blessing, and life of possibilities of joy, no man travels very far along the road without feeling that the burden of sorrow is a burden that we all have to carry. There are blessings in plenty, there is mirth more than enough. There is 'the laughter' which is 'the crackling of thorns' under a pot. There are plenty of distractions and amusements, 'blessings more plentiful than hope'; but yet the ground tone of every human life, when the first flush of inexperience and novelty has worn off, apart from God, is sadness, conscious of itself sometimes, and driven to all manner of foolish attempts at forgetfulness, unconscious of itself sometimes, and knowing not what is the disease of which it languishes. There it is, like some persistent minor in a great piece of music, wailing on through all the embroidery and lightsomeness of the cheerfuller and loftier notes. 'Every heart knoweth its own bitterness,' and every heart _has_ a bitterness of its own to know. I do not understand how it is that men who have no religion in them can bear their own sorrows and see their neighbours' and not go mad. Sometimes the world seems to me to be moving round its central sun with a doleful atmosphere of sighs wherever it goes, and all the mirth and stir and bustle are but like a thin crust of grass with flowers upon it, cast across the sulphurous depths of some volcano that may slumber for a while, but is there all the same. Brother! you and I, away from Jesus Christ, have to face the certainties of ignorance, of sin, of sorrow--ignorance unenlightened, sin unconquered, sorrow uncomforted.
