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

If we act towards (God) as if His holy Word would not now convert and sanctify, comfort and conquer, as it used to do, we are in this horrible position of practical unbelief. His holy Book, in days gone by, did great wonders. It was like Goliath’s sword, of which David said, “There is none like that; give it me.” It was double-edged, and even he that played with it, might wound himself to spiritual death. Many have wrested the Word to their own destruction. “But surely the Word has not the same power now?” Try it. Give the Bible still to the wicked, to the careless, and the thoughtless; read it to them; induce them to read it; and see if it does not still convert. When you are in great trouble, turn to the Book, and pray the Holy Ghost to bless it, and see if it does not comfort you. In your darkest hour you shall find light in it; when you are ready to give up in despair, you shall to be strengthened, and return to your labor with hope, if you do but search it, and believe its message. It is full of consolation. Never think that the Spirit cannot bless the Word to you, as He used to do. He is not straitened. When you hear and do not profit, it is your hearing that is wrong, not His power that has failed. When you read the Bible, and have not that enjoyment you once had, be you sure that it is your own fault. The meat is as rich; you have lost your appetite. The Spirit of God is not straitened. There is as much inspiration in this Book as when it was first penned. It is still inspired; and he that reads it aright, still feels its inspiring influence, as God comes into his heart through His own Word. The Spirit of God in the Book, and through the Book, is not straitened. Let us keep to it. Let us preach it more and more. Let us take care that our sermons are made out of the Bible, not out of our own heads; then, speaking God’s Word, we shall see that the Spirit of God is not straitened.~ C.H. Spurgeon
