Look unto Me, and be ye saved… – Isaiah 45:22
Fight sinful habits with the Word of God, as the sword of the Spirit: so only will you conquer your evil self. Find a text of Scripture that will cleave your sin down to the chine, or stab it to the heart. “Alas! Satan tempts me horribly,” cries one; “I have been lately assailed in many ways.” Have you? You are not the first. Our divine Lord in the wilderness was tempted of the devil. He might have fought Satan with a thousand weapons; but He chose to defeat him with this one only. He said, “It is written; it is written; it is written.” He pricked the foeman so sorely with this sharp point, that the arch-adversary thought to try the same sword; and he also began to say, “It is written.” But he cut himself with this sword, for he did not quote the passages correctly, nor give the whole of them; and the Master soon found the way to knock aside his sword, and wound him still more. Follow your Lord’s example. “Oh, but,” says one,” I am so low in spirits.” Very well; fight lowness of spirits with the Word of God. “The doctor recommended me,” says one, “to take a little spirits to raise my spirits.” Those doctors are always having this sin laid to their charge. I am not so sure that they are not often maligned. You like the dose, and that is why you take it. Try the Word of God for lowness of spirits, and you will have found a sure remedy. I find, if I can lay a promise under my tongue, like a sweet lozenge, and keep it in my mouth or mind all the day long, I am happy enough. If I cannot find a Scripture to comfort me, then my inward troubles are multiplied. Fight despondency and despair with the sword of the Spirit. I cannot tell what your particular difficulty may be at this moment; but I give you this direction for all holy warfare- “Take the sword of the Spirit, which is the word of God.”
God grant you His Spirit’s aid, for Christ’s sake! Amen. ~ C.H. Spurgeon
