It is not merely the physical strength proper to their age, nor the mere unworn buoyancy and vigour which sorrows and care and responsibilities have not thinned and weakened. These are great and precious gifts. We never know how precious they are until they have slipped away from us. These are great and precious gifts, to be preserved as long as may be, by purity and by moderation, and to be used for high and great purposes. But the strength that is in thews and muscles is not the strength that the Apostle is speaking about here, nor anything that belongs simply to the natural stage of your development, whether it be purely physical or purely mental. Samson was a far weaker man than the poor little Jew whose bodily presence was weak and his speech contemptible,' and who all his days carried about with him that thorn in the flesh.' It is not your body that is to be strong, but yourselves.
Now the foundation of all true strength lies here, in a good, strong will. In this world, unless a man has learned to say No!' and to say it very decidedly, and to stick to it, he will never come to any good. Two words contain the secret of noble life: Resist!' and Persist!' And the true strength of manhood lies in this mainly, that, in spite of all antagonisms, hindrances, voices, and things that array themselves against you, having greatly resolved, you do greatly do what you have resolved, and having said I will!' let neither men nor devils lead you to say, I will not.' Depend upon it, that to be weak in this direction is to be weak all through. Strong passions make weak men. And a strong will is the foundation, in this wicked and antagonistic world in which we live, of all real strength.
But then the strength that I would have you seek, and strive to cultivate, must be a strength of will founded upon strong reason. Determination unenlightened is obstinacy, and obstinacy is weakness. A mule can beat you at that: Be ye not as the mule, which have no understanding.' A determination which does not take into its view all the facts of the case, nor is influenced by these, has no right to call itself strength. It is only, to quote a modern saying--I know not whether true of the person to whom it was originally applied or no--is only a lath painted to look like iron.' Unintelligent obstinacy is folly, like the conduct of some man who sticks to his pick and his task in a quarry after the bugle has warned him of an impending explosion, which will blow him to atoms.
But that is not all. A strong will, illuminated by a strong beam of light from the understanding, must be guided and governed by a strong hand put forth by Conscience. I should like' is the weakling's motto. I will' may be an obstinate fool's motto. I ought, therefore, God helping me, and though the devil hinders me, I will,' is a man's. Conscience is king. To obey it is to be free; to neglect it is to be a slave.
Is not this a better ideal for life than gathering any outward possessions, however you may succeed therein? A thousand things will have to be taken into account, and may help or may hinder outward prosperity and success. But nobody can hinder you working at your character and succeeding in making it what it ought to be; and to form character is the end of life. To be weak is miserable, doing or suffering.' Ay! that is true, though Milton put it into the devil's mouth. And there is only one strength that will last, for even the youths shall faint and be weary, and the young men shall utterly fail.' But the strength of a fixed and illuminated and conscience-guided will, which governs the man and is governed by God, shall never faint or grow weak. This is the strength which we should seek, and which I ask you to make the conscious aim of your lives.
