Spurgeon's Advice On Sermons

"Do not close a single sermon without addressing the ungodly, but at the same time set yourself seasons for a determined and continuous assault upon them, and proceed with all your soul to the conflict. On such occasions aim distinctly at immediate conversions; labour to remove prejudices, to resolve doubts, to conquer objections, and to drive the sinner out of his hiding-places at once." 

(From Lectures to my Students as cited here)

I agree with Spurgeon. How about you? I pray more of my Hardshell preacher brethren will heed this advice from the great Baptist preacher.
