"In dealing with the sinners obstinacy we have tested the Words of the Lord. There are men who cannot be convincedor persuaded. They doubt everything and with closed teeth they resolve not to believe though a man declare it to them.They are encased in the armor of prejudice and they cannot be wounded with the sharpest arrows of argument thoughthey profess great openness to conviction. What is to be done with the numerous people who are related to Mr. Obstinate? You might as well argue with an express-train as with Mr. Obstinatehe runs on and will not stop though a thousand should stand in his way.Will the Words of God convince him? There are some in this place today of whom I should have saidif I hadknown them before their conversionthat it was a vain task to preach the Gospel to them. They so much loved sin andso utterly despised the things of God. Strangely enough, they were among the first to receive the Word of God when they came under the sound of it. It came to them in its native majesty, in the power of the Holy Spirit. It spoke with a commanding tone to their inmost heart. It threw open the doors that had long been shut up and rusted on their hinges and Jesus entered to save and reign! These who had defiantly brandished their weapons threw them down and surrendered unconditionally to almighty Love, willing Believers in the Lord Jesus. Brethren, we have only to have faith in Gods Word and speak it out straight and we shall see proud rebels yielding. No mind is so desperately set on mischief or so resolutely opposed to Christ that it cannot be made to bow before the power of the Words of God. Oh, that we used more the naked sword of the Spirit! I am afraid we keep this two-edged sword in a scabbard and somewhat pride ourselves that the sheath is so elaborately adorned. What is the use of the sheath? The sword must be made bare and we must fight with it without attempting togarnish it.Tell forth the Words of God. Omit neither the terrors of Sinai nor the love notes of Calvary. Proclaim the Wordwith all fidelity as you know it and cry for the power of the Highest and the most obstinate sinner out of Hell can be laid low by its means. The Holy Spirit uses the Word of Godthis is His one battering ram with which He casts down the strongholds of sin and self in those human hearts with which He effectually deals. The Word of God will bear the tests furnished by the hardness of the natural heart and it will, by its operations, prove its Divine origin."Taken from Spurgeon's sermon, "The Bible Tried and Proved"
