Spurgeon on Preaching:

The word “sermon” is said to signify a thrust, and, therefore, in sermonizing it must be our aim to use the subject in hand with energy and effect, and the subject must be capable of such employment. To choose mere moral themes will be to use a wooden dagger; but the great truths of revelation are as sharp swords. Keep to doctrines which stir the conscience and the heart. Remain unwaveringly the champions of a soul-winning gospel. God’s truth is adapted to man, and God’s grace adapts man to it. There is a key which, under God, can wind up the musical box of man’s nature; get it, and use it daily. Hence I urge you to keep to the old-fashioned gospel, and to that only, for assuredly it is the power of God unto salvation. Of all I would wish to say this is the sum; my brethren, preach CHRIST, always and evermore. He is the whole gospel. His person, offices, and work must be our one great, all-comprehending theme. The world needs still to be told of its Savior, and of the way to reach him. Justification by faith should be far more than it is the daily testimony of Protestant pulpits; and if with this master truth there should be more generally associated the other great doctrines of grace, the better for our churches and our age. If with the zeal of Methodists we can preach the doctrine of Puritans, a great future is before us. The fire of Wesley, and the fuel of Whitefield, will cause a burning which shall set the forests of error on fire and warm the very soul of this cold earth. We are not called to proclaim philosophy and metaphysics, but the simple gospel. Man’s fall, his need of a new birth, forgiveness through an atonement, and salvation as the result of faith, these are our battle-ax and weapons of war. We have enough to do to learn and teach these great truths, and accursed be that learning which shall divert us from our mission, or that willful ignorance which shall cripple us in its pursuit. More and more am I jealous lest any views upon prophecy, church government, politics, or even systematic theology, should withdraw one of us from glorying in the cross of Christ. Salvation is a theme for which I would fain enlist every holy tongue. I am greedy after witnesses for the glorious gospel of the blessed God. Oh, that Christ crucified were the universal burden of men of God. Your guess at the number of the beast, your Napoleonic speculations, your conjectures concerning a personal Antichrist—forgive me, I count them but mere bones for dogs; while men are dying, and hell is filling, it seems to me the veriest drivel to be muttering about an Armageddon at Sebastopol or Sadowa or Sedan, and peeping between the folded leaves of destiny to discover the fate of Germany. Blessed are they who read and hear the words of the prophecy of the Revelation, but the like blessing has evidently not fallen on those who pretend to expound it; for generation after generation of them have been proved to be in error by the mere lapse of time, and the present race will follow to the same inglorious sepulcher. I would sooner pluck one single brand from the burning than explain all mysteries. To win a soul from going down into the pit is a more glorious achievement than to be crowned in the arena of theological controversy as Doctor Sufficientissimus; to have faithfully unveiled the glory of God in the face of Jesus Christ will be in the final judgment accounted worthier service than to have solved the problems of the religious Sphinx, or to have cut the Gordian knot of apocalyptic difficulty. Blessed is that ministry of which CHRIST IS ALL.*

For His Glory,
