Many of you have learnt, I feel sure of it, to feel during these your school days, the satisfaction of living here a true and worthy life; you have tasted of that pleasure which the careless, the indifferent, and the sinful hardly taste at all, the pleasure that dwells with the consciousness of earnest effort and sincere striving after the best things within us. The love of Christ may have taken hold upon you; the associations of your school and its inheritance of great and good examples, or the sense of honour may have stirred you; the feeling of your closeness in life to those around you, and of the strong currents of mutual influence, may have opened your eyes to what you owe to your neighbour and to the claims of social duty. Some one of these causes, or it may be some other cause, may have given you strength and power to walk amongst us in the narrow way of good habit and good influence. And wherever this is so, we thank God. But the question to-day is, What assurance do you feel that this will continue? When we go elsewhere, what habits, what tendencies, what fixed bent of spirit and character shall we exhibit? Knowing as we do how strongly the forces of the outer world will act upon us, it is never a useless warning which bids us take care that in new spheres we do not forget our old principles, or lay aside any good habits. "Blessed are ye that sow beside all waters." We have learnt to look upon certain laws of conduct and feeling, certain duties, certain standards of life, as beyond dispute, and fundamental. If so, they are also of universal application; and we should hold them as things which are altogether independent of the customs, traditions, or tone of any society into which we may go. It is probable that some of you may find this doctrine not altogether free from difficulties before many weeks are over. You may find yourselves young and apparently uninfluential members of some society in which the standards of life are low, and you may be tempted to think, under the pressure of surrounding opinion, that you are not called upon to set up or display any standard of your own; and there is always a chorus of voices ready enough to echo any such tempting suggestions. But if ever you are tempted thus to let slip the things you have learnt and accepted, the voice of Isaiah should prove a help and a safeguard. And its exhortation is supported by the respect and admiration you feel for any one who has the courage to stand alone in such a case, true to his rooted convictions.
