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.
II. Now note, secondly, how to get it.
'Ye are strong, and the Word of God abideth in you.' Those young Asiatic Christians, that John had in his eye, had learned the secret and the conditions of this strength; and not only in limb and sinew, or in springy and elastic buoyancy of youthful, mental, and spiritual vigour were they strong, but they were so because 'the Word of God abode in them.' Now, there are two significations of that great expression, both of them frequent in John's Gospel, and both of them, I think, transferred to this Epistle, each of which may yield us a word of counsel. By 'the Word of God,' as I take it, is meant--perhaps I ought to say _both_, but, at all events, _either_--the revelation of God's truth in Holy Scripture, or the personal revelation of the will and nature of God in Jesus Christ our Lord. Whichever of these two meanings--and at bottom they come to be one--we attach to this expression, we draw from them an exhortation. Let me put this very briefly.
Let me say to you, then, if you want to be strong, let Scripture truth occupy and fill and be always present to your mind. There are powers to rule and to direct all conduct, motive powers of the strongest character in these great truths of God's revelation. They are meant to influence a man in all his doings, and it is for us to bring the greatest and solemnest of them to bear on the smallest things of our daily life. Suppose, now, that you go to your work, and some little difficulty starts up in your path, or some trivial annoyance ruffles your temper, or some lurking temptation is suddenly sprung upon you. Suppose your mind and heart were saturated with God's truth, with the great thoughts of His being, of His love, of His righteousness, of Christ's death for you, of Christ's presence with you, of Christ's guardianship over you, of Christ's present will that you should walk in His ways, of the bright hopes of the future, and the solemn vision of that great White Throne and the retribution that streams thence, do you think it would be possible for you to fall into sin, to yield to temptation, to be annoyed by any irritation or bother, or overweighted by any duty? No! Whosoever lives with the thoughts that God has given us in His Word familiar to His mind and within easy reach of His hand, has therein an armlet against all possible temptation, a test that will unveil the hidden corruption in the sweetest seductions, and a calming power that will keep his heart still and collected in the midst of agitations. If the Word of God in that lower sense of the principles involved in the gospel of Jesus Christ, dwell in your hearts, the fangs are taken out of the serpent. If you drink any deadly thing it shall not hurt you, and you will 'be strong in the Lord and in the power of His might.'
