Spurgeon is a great example of gospel preaching always bringing the great truths to bear on the minds and hearts of his hearers. This is a great quote.

“I may not have many more opportunities of preaching, and I make up my mind to this one thing, that I will waste no time upon secondary themes, but when I do preach it shall be the gospel or something closely bearing upon it.  I will endeavour each time to strike under the fifth rib, and never beat the air.  Those who have a taste for superfluities may take their fill of them, it is for me to keep to the great necessary truths by which men’s souls are saved.  My work is to preach Christ crucified and the gospel, which gives men salvation through faith.  I hear every now and then of very taking sermons about some bright new nothing or another.  Some preachers remind me of the emperor who had a wonderful skill in carving men’s heads upon cherry stones.  What a multitude of preachers we have who can make wonderfully fine discourses out of a mere passing thought, of no consequence to anyone.  But we want the gospel.  We have to live and die, and we must have the gospel.  Certain of us may be cold in our graves before many weeks are over, and we cannot afford to toy and trifle: we want to see the bearings of all teachings upon our eternal destinies, and upon the gospel which sheds its light over our future.”
(Sermons by Rev. C. H. Spurgeon, ed. Sir W. Robertson Nicoll [Thomas Nelson and Sons, nd.]),388; preached April 9, 1882.  Spurgeon actually did live and preach for 10 more years).
