For the word of God is quick, and powerful… – Hebrews 4:12

The Holy Spirit wields no sword but the Word of God. This wonderful Book, which contains the utterances of God’s mouth, is the one weapon which the Holy Ghost elects to use for His warlike purposes. It is a spiritual weapon, and so is suitable to the Holy Spirit. The weapons of His warfare are not carnal: He never uses either persecution or patronage, force or bribery, glitter of grandeur, or terror of power. He works upon men by the Word, which is suitable to His own spiritual nature, and to the spiritual work which is to be accomplished. While it is spiritual, this weapon is “mighty through God.” A cut from the Word of God will cleave a man’s spirit from head to foot; so sharp is this sword. Though by long practice in sin a man may have coated himself as with mail impenetrable, yet the Word of the Lord will divide the northern iron and the steel. The Holy Ghost can make a man feel the divine power of the sacred Word in the very center of his being. For battling with the spirits of man, or with spirits of an infernal kind, there is no weapon so keen, so piercing, so able to divide between the joints and marrow, so penetrating as to the thoughts and intents of the heart. The Word, in the Spirit’s hand, gives no dash-wound, but cuts into the man’s heart, and so wounds him that there is no healing save by supernatural power. The wounded conscience will bleed; its pains will be upon it day and night; and though it seek out a thousand medicines, no salve but one can cure a gash which this terrible sword has made. This weapon is two-edged; indeed, it is all edge; and whichever way it strikes, it wounds and kills. There is no such a thing as the flat of the sword of the Spirit: it has a razor edge every way. Beware how you handle it, you critics; it may wound even you: it will cut you to your destruction, one of these days, except ye be converted. He that uses the Word in the Lord’s battles may use it upon carnal hopes, and then strike back upon unbelieving fears; he may smite with one edge the love of sin, and then with the other the pride of self-righteousness. It is a conquering weapon in all ways, this wondrous sword of the Spirit of God. ~ C.H. Spurgeon

For the word of God is quick, and powerful, and sharper than any two-edged sword… – Hebrews 4:12

The Word of God in the hand of the Spirit wounds very terribly, and makes the heart of man to bleed. Do you not remember, some of you, when you used to be gashed with this sword Sunday after Sunday? Were you not cut to the heart by it, so as to be angry with it? You almost made up your mind to turnaway from hearing the gospel again. That sword pursued you, and pierced you in the secrets of your soul, and made you bleed in a thousand places. At last you were “pricked in the heart”, which is a far better thing than being “cut to the heart”; and then execution was done, indeed. That wound was deadly, and none but He that killed could make you alive. Do you recollect how, after this, your sins were slain one after another? Their necks were laid on the block, and the Spirit acted as an executioner with His sword. After that, blessed be God, your fears, and doubts, and despair, and unbelief, were also hacked to pieces by this same sword. The Word gave you life; but it was at the first a great killer. Your soul was like a battle-field after a great fight, under the first operations of the divine Spirit, whose sword returneth not empty from the conflict.

Beloved, the Spirit of God has war with the Amalek of evil and error from generation to generation. He will spare none of the evils which now pollute the nations; His sword will never be quiet till all these Canaanites are destroyed. The Holy Spirit glorifies Christ not only by what He reveals, but also by what He overturns. The strife may be weary, but it will be carried on from age to age, till the Lord Jesus shall appear; for ever shall the Spirit of God espouse the cause of love against hate, of truth against error, of holiness against sin, of Christ against Satan. He will win the day, and those who are with Him shall in His might be more than conquerors. ~ C.H. Spurgeon

And take the helmet of salvation, and the sword of the Spirit, which is the word of God. – Ephesians 6:17

Our defense and our conquest must be obtained by sheer fighting. Many try compromise; but if you are a true Christian, you can never do this business well. The language of deceit fits not a holy tongue. The adversary is the father of lies, and those that are with him understand the art of equivocation; but saints abhor it. If we discuss terms of peace, and attempt to gain something by policy, we have entered upon a course from which we shall return in disgrace. We have no order from our Captain to patch up a truce, and get as good terms as we can. We are not sent out to offer concessions. It is said that if we yield a little, perhaps the world will yield a little also, and good may come of it. If we are not too strict and narrow, perhaps sin will kindly consent to be more decent… Assuredly this is not the order which our Captain has issued. When peace is to be made, He will make it Himself, or He will tell us how to behave to that end… We are not to cease from conflict, and try to be as agreeable as we can with our Lord’s foes, frequenting their assemblies, and tasting their dainties. No such orders are written here. You are to grasp your weapon, and go forth to fight… We have no orders to be quiet, and take matters easily. No; we are to pray always, and watch constantly. The one note that rings out from the text is this:-TAKE THE SWORD! TAKE THE SWORD! No longer is it, talk and debate! No longer is it, parley and compromise! The word of thunder is-Take the sword. The Captain’s voice is clear as a trumpet-Take the sword!

May the Holy Spirit help me! ~ C.H. Spurgeon
