Only remember, it is dangerous, too. It may become want of reverence, which is ruinous, or presumption and rashness. Remember what a cynical head of a college said, 'None of us is infallible, not even the youngest,' and blend modesty with confidence, and yet be buoyant and strong, and trust in the power that may make you strong. And then your self-confidence will not be rashness. 'Thou wentest whither thou wouldest.' That is another characteristic of youth, after it has got beyond the schoolboy stage. Your own will tends to become your guide. For one thing, at your time of life, most other inward guides are comparatively weak. You have but little experience. Most of you have not cultivated largely the habit of patient reflection, and thinking twice before you act once. That comes: it would not be good that it should be over-predominant in you. 'Old heads on young shoulders' are always monstrosities, and it is all right that, in your early days, you should largely live by impulse, if only, as well as a will, there be a conscience at work which will do instead of the bitter experience which comes to guide some of the older of us. Again, yours is the age when passion is strong. I speak now especially to young men. Restraints are removed for many of you. There are dozens of young men listening to me now, away from their father's home, separated from the purifying influence of sisters and of family life, living in solitary lodgings, at liberty to spend their evenings where they choose, and nobody be a bit the wiser. Ah, my dear young friend! 'thou wentest whither thou wouldest' and thou wouldest whither thou oughtest not to go. There is nothing more dangerous than getting into the habit of saying, 'I do as I like,' however you cover it over. Some of you say, 'I indulge natural inclinations; I am young; a man must have his fling. Let me sow my wild oats in a quiet corner, where nobody will see the crop coming up; and when I get to be as old as you are, I will do as you do; young men will be young men,' etc., etc. You know all that sort of talk. Take this for a certain fact: that whoever puts the reins into the charge of his own will when he is young, has put the reins _and the whip_ into hands which will drive over the precipice. My friend! 'I will' is no word for you. There is a far diviner and better one than that--'I ought.' Have you learnt that? Do you yield to that sovereign imperative, and say, 'I _must_, because I _ought_ and, therefore, I _will_'? Bow passion to reason, reason to conscience, conscience to God--and then, be as strong in the will and as stiff in the neck as ever you choose; but only then. So much, then, for my first picture. II. Now let me ask you to turn with me for a moment to the second one--What you will certainly become if you live.
