A Sharp Sword
Isaiah 49:2
And he has made my mouth like a sharp sword; in the shadow of his hand has he hid me, and made me a polished shaft…


1. God does not undo, in His relationship to us as Re-creator, the work which He has already performed as Creator. He does not strip us of our natural faculties, and endow us with others altogether distinct from these. Our natural faculties are in themselves neither good nor bad, but in every case are capable of development, either in the direction of good or of evil. When first the grace of God finds us, the powers of evil have more or less infected our nature, and most of our faculties (if not all of them) have exhibited a downward inclination; our members have become "instruments of unrighteousness," the weapons which Satan has used to do his own fell work. It is upon these dishonoured faculties that God lays His hand when He enters and takes possession of the new-created soul. What He demands on our part is, that these members should be surrendered to Him, as they formerly were to the powers of darkness.

2. The prophet here speaks of one important faculty which exercises an influence for good or evil second to none that affects society — the tongue. The faculty of speech is one of the noblest endowments of humanity, distinguishing us, as it does, from all the lower animals, rendering social life possible, and binding humanity into one. How much of evil originates with the tongue! And yet what a mighty engine for good language may be! Surely God has put no small honour on human speech when He permits His own Son to be described as "the Word" of God.

3. How many of us have endeavoured to use our tongues in the service of God, and yet our efforts have been singularly weak and unsuccessful. Let us not be discouraged, but listen to this word of power: "I have made thy mouth a sharp sword" — sharp no longer for sarcasm and cutting scorn. The withering scoff, the poisoned slander, the bitter reproach, are no longer to proceed, like a sharp two-edged sword, from those consecrated lips of thine; but, if thou wouldst but believe it, a new power has been communicated, in virtue of which that very member, which was of old so keen-edged a weapon in the hands of the destroyer, is now to be equally sharp and pointed in the grasp of its Divine Master. But have we yet begun to be discontented with our want of sharpness? Are we ready to be used by God as a sharp sword? Have we counted the cost? Are we prepared for the consequences? If we are, our weakness matters not. God can use us. "Fear not, thou worm Jacob; I will make thee a sharp threshing instrument, having teeth, and thou shalt break in pieces the mountains." How many of our well-meant efforts fail for want of teeth!

4. What is required in order to render us efficient instruments in the hands of God?

(1) Definiteness of purpose. The man whose mouth is a sharp sword will speak, not for speaking's sake, nor to ease his conscience, but to reach the heart.

(2) Incisiveness of language. Our words need not be ungentle nor severe, and yet they may be pointed.

(3) Earnestness.

(4) One other characteristic will be embodied in the word "now." The man who speaks for God will ever remember that "the King's business requires haste." "The Holy Ghost saith, To-day"; and he who speaks in the Spirit will speak as the Spirit.
