And I press it upon you for another reason, because you have special temptations to make your ways unclean. It is a fearful ordeal that every young man and woman has to face, as he or she steps across the dividing boundary between childhood and youth, when parental authority is weakened, and the leading-strings are loosened, and the young swimmer is as it were cut away from the buoys, and has to battle with the waves alone. There are hundreds of young men in Manchester, there are many of them here now, who have come up into this great city from quiet country homes where they were shielded by the safeguards of a father's and a mother's love and care, and have been flung into this place, with its every street swarming with temptation, and companions on the benches of the university, at the desks, in the warehouses, and the workshops, leading them away into evil and teaching them the devil's alphabet--young men with their evenings vacant and with no home. Am I speaking to any such standing in slippery places? Oh, my young friend! there is nothing in all these temptations, the fascinations of which you are beginning to find out, there is nothing in them all worth soiling your fingers for; there is nothing in them all that will pay you for the loss of your innocence. There is nothing in them all except a fair outside with poison at the core. You see the 'primrose path'; you do not see, to use Shakespeare's solemn words, 'the everlasting burnings' to which it leads. And so I plead with you all, young men and women, to lay this question to heart; and I beseech you to credit me when I say to you that you have not yet touched the gravest and the most pressing problem of life unless you have asked yourselves in a serious mood of deep reflection, 'Wherewithal shall I cleanse my way?'
II. So much for the first point to which I ask your attention. Now, secondly, look at this answer, which tells us that we can only make our way clean on condition of constant watchfulness. 'By taking heed thereto.'
That seems a very plain, simple, common-sense answer. The best made road wants looking after if it is to be kept in repair. What would become of a railway that had no surfacemen and platelayers going along the line and noticing whether anything was amiss? I remember once seeing a bit of an old Roman road; the lava blocks were there, but for want of care, here a young sapling had grown up between two of them and had driven them apart; there they were split by the frost, here was a great ugly gap full of mud; and the whole thing ended in a jungle. How shall a man keep his road in repair? 'By taking heed thereto.' Things that are left to go anyhow in this world have a strange knack of going one how. You do not need anything else than negligence to ensure that things will come to grief.
And so, at first sight, my text simply seems to preach the plain truth: if you want to keep your road right, look after it. But if you look at your Bibles, you will see that the word 'thereto' is a supplement, and that all that the Psalmist really says is 'by taking heed.' And perhaps it is to himself rather than to his 'way' that a man is exhorted to 'take heed.' 'Take heed to thyself' is the only condition of a pure and noble life.
That such a condition is necessary, will appear very plain from two considerations. First, it is clear that there must be constant watchfulness, if we consider what sort of a world this is that we have got into And it is also plain, if we consider what sort of creatures we are that have got into it.
