My text points to another fact, as certain as gravitation, that the faintness and weariness and decay of the bodily strength will be accompanied with a parallel change in your feelings. We are drawn onward by hopes, and when we get them fulfilled we find that they are disappointing. Custom, which weighs upon us 'heavy as frost, and deep almost as life,' takes the edge off everything that is delightsome, though it does not so completely take away the pain of things that are burdensome and painful. Men travel from a tinted morning into the sober light of common day, and with failing faculties and shattered illusions and dissipated hopes, and powers bending under the long monotony of middle life, most of them live. Now all that is the veriest threadbare morality, and I dare say while I have been speaking, some of you have been thinking that I am repeating platitudes that every old woman could preach. So I am. That is to say, I am trying to put into feeble words the universal human experience. That is your experience, and what I want to get you to think about now is that, as sure as you are living and rejoicing in your youth and strength, this is the fate that is awaiting you--'the youths shall faint and be weary, and shall utterly fall.'
Well, then, one question: Do you not think that, if that is so, it would be as well to face it? Do you not think that a wise man would take account of all the elements in forecasting his life and would shape his conduct accordingly? If there be something certain to come, it is a very questionable piece of wisdom to make that the thing which we are most unwilling to think about. I do not want to be a kill-joy; I do not want to take anything out of the happy buoyancy of youth. I would say, as even that cynical, bitter Ecclesiastes says, 'Rejoice, O young man, in thy youth; and let thy heart cheer thee in the days of thy youth.' By all means; only take all the facts into account, and if you have joys which shrivel up at the touch of this thought, then the sooner you get rid of such joys the better. If your gladness depends upon your forcibly shutting your eyes to what is inevitably certain to come about, do you not think that you are living in a fool's paradise that you had better get out of as soon as possible? There is the fact. Will you be a wise and brave man and front it, and settle how you are going to deal with it, or will you let it hang there on your horizon, a thunder-cloud that you do not like to look at, and that you are all the more unwilling to entertain the thought of, because you are so sure that it will burst in storm? Lay this, then, to heart, though it is a dreary certainty, that weariness and decay are sure to be your fate.
II. Now turn, in the next place, to the blessed opposite possibility of inexhaustible and immortal strength. 'They that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run and not be weary; they shall walk and not faint.' The life of nature tends inevitably downward, but there may be another life within the life of nature, which shall have the opposite motion, and tend as certainly upwards. 'The youths shall faint and be weary'--whether they be Christians or not, the law of decay and fatigue will act upon them; but there may be that within each of us, if we will, which shall resist that law, and have no proclivity whatsoever to extinction in its blaze, to death in its life, to weariness in its effort, and shall be replenished and not exhausted by expenditure. 'They that wait upon the Lord shall renew their strength,' and, in all forms of motion possible to a creature they shall expatiate and never tire. So let us look on this blessed possibility a little more closely.
