' . . . Whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.'--PHIL. iv. 8.
I am half afraid that some of you may think, as I have at times thought, that I am too old to preach to the young. You would probably listen with more attention to one less remote from you in years, and may be disposed to discount my advices as quite natural for an old man to give, and quite unnatural for a young man to take. But, dear friends, the message which I have to bring to you is meant for all ages, and for all sorts of people. And, if I may venture a personal word, I proved it, when I stood where you stand, and it is fresher and mightier to me to-day than it ever was.
You are in the plastic period of your lives, with the world before you, and the mightier world within to mould as you will; and you can be almost anything you like, I do not mean in regard to externals, or intellectual capacities, for these are only partially in our control, but in regard to the far more important and real things--viz. elevation and purity of heart and mind. You are in the period of life to which fair dreams of the future are natural. It is, as the prophet tells us, for 'the young man' to 'see visions,' and to ennoble his life thereafter by turning them into realities. Generous and noble ideas ought to belong to youth. But you are also in the period when there is a keen joy in mere living, and when some desires, which get weaker as years go on, are very strong, and may mar youthful purity. So, taking all these into account, I have thought that I could not do better than press home upon you the counsels of this magnificent text, however inadequately my time may permit of my dealing with them; for there are dozens of sermons in it, if one could expand it worthily.
But my purpose is distinctly practical, and so I wish just to cast what I have to say to you into the answer to three questions, the three questions that may be asked about everything. What? Why? How?
I. _What_, then, is the counsel here?
'Think on these things.' To begin with, that advice implies that we can, and, therefore, that we should, exercise a very rigid control over that part of our lives which a great many of us never think of controlling at all. There are hosts of people whose thoughts are just hooked on to one another by the slightest links of accidental connection, and who scarcely ever have put a strong hand upon them, or coerced them into order, or decided what they are going to let come into their minds, and what to keep out. Circumstances, the necessities of our daily occupations, the duties that we owe to one another, all these make certain streams of thought very necessary, and to some of us very absorbing. And for the rest--well! 'He that hath no rule over his own spirit is like a city broken down, without walls'; anybody can go in, and anybody can come out. I am sure that amongst young men and women there are multitudes who have never realised how responsible they are for the flow of the waves of that great river that is always coming from the depths of their being, and have never asked whether the current is bringing down sand or gold. Exercise control, as becomes you, over the run and drift of your thoughts. I said that many of us had minds like cities broken down. Put a guard at the gate, as they do in some Continental countries, and let in no vagrant that cannot show his passport, and a clear bill of health. Now, that is a lesson that some of you very much want.
