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
