Spurgeon said

You may depend upon it that you may make men understand the truth if you really want to do so; but if you are not in earnest, it is not likely that they will be. If a man were to knock at my door in the middle of the night, and when I put my head out of the window to see what was the matter, he should say, in a very quiet, unconcerned way, "There is a fire at the back part of your house," I should have very little thought of any fire, and should feel inclined to empty a jug of water over him. If I am walking along, and a man comes up to me, and says, in a cheerful tone of voice, "Good afternoon, sir, do you know that I am starving? I have not tasted food for ever so long, indeed, I have not;" I should reply, "My good fellow, you seem to take it very easy; I do not believe you want for much, or you would not be so unconcerned about it." Some men seem to preach in this fashion:�"My dear friends, this is Sunday, so here I am; I have been spending my time in my study all the week, and now I hope you will listen to what I have to say to you. I do not know that there is anything in it that particularly concerns you, it might have some connection with the man in the moon; but I understand that some of you are in danger of going to a certain place which I do not wish to mention, only I hear that it is not a nice place for even a temporary residence. I have especially to preach to you that Jesus Christ did something or other, which, in some way or other, has something to do with salvation, and if you mind what you do"�and so on�"it is possible that you will"�and so on, and so on. That is, in a nutshell, the full report of many a discourse. There is nothing in that kind of talk that can do anybody any good; and after the man has kept on in that style for three-quarters of an hour, he closes by saying, "Now it is time to go home," and he hopes that the deacons will give him a couple of guineas for his services. Now, brethren, that sort of thing will not do. We did not come into the world to waste our own time, and other people's, in that fashion.
