I think it would be very useful to some of you who are not yet adepts at the art of illustration if you were to read hooks in which there is an abundance of metaphor, simile, and emblem. I am not going fully into that subject on this occasion, because this lecture is only preliminary to the next two that I hope to deliver, in which I will try to give you a list of cyclopedias of anecdotes and illustrations, and books of fables, emblems, and parables; but I advise you to study such works as Gurnall's "Christian in Complete Armor," or Matthew Henry's "Commentary," with the distinct view of noticing all the illustrations, emblems, metaphors, and similes that you can find. I should even select non-comparisons; I like Keach's "Metaphors," where he points out the disparity between the type and the Antitype. Sometimes, the contrasts between different persons or objects will be as instructive as their resemblances.

When you have read the book once, and tried to mark all the figures, go through it again, and note all the illustrations you missed in your first reading. You will probably have missed many; and you will be surprised to find that there are illustrations even in the words themselves. How frequently a word is itself a picture! Some of the most expressive words that are found in human language are like rich gems, which have passed before your eye very often, but you have not had time to handle or to value them. In your second examination of the book, you will notice, perhaps, what eluded you the first time, and you will find many illustrations which are merely hinted at, instead of being given at length. Do as I have recommended with a great many books. Get copies that you can afford to mark with a colored pencil, so that you will be sure to see the illustrations readily; or put them down in one of your note-books.

I am sure that those brethren who begin early to keep a record of such things act wisely. The commonplace-books of the old Puritans were invaluable to them. They would never have been able to have compiled such marvelous works as they did if they had not been careful in collecting and arranging their matter under different heads; and thus, all that they had ever read upon any subject was embalmed and preserved, and they could readily refer to any point that they might require, and refresh their memories and verify their quotations. Some of us, who are very busy, may be excused from that task; we must do the best we can; but some of you, who go to smaller charges, in the country especially, ought to keep a commonplace-book, or else I am afraid you will get to be very commonplace yourselves.

Your selection of similes, metaphors, parables, and emblems will not be complete unless you also search the Scriptures to find the illustrations that are recorded there. Biblical allusions are the most effective methods of illustrating and enforcing the truths of the gospel; and the preacher who is familiar with his Bible will never be at a loss for an instance of that which "is profitable for doctrine, for reproof, for correction, for instruction in righteousness." The Lord must have meant us thus to use his Word, otherwise he would not have given us, in the Old Testament, such a number of types and symbols of truths, to be afterward more fully revealed under the gospel dispensation.

Such a collection of illustrations as I have suggested will come very handy to you in future days, and you will be reminded, by the comparisons and figures used by others, to make comparisons and figures for yourself. Familiarity with anything makes us au fait at it; we can learn to do almost anything by practice. I suppose that I could, by degrees, learn to make a tub if I spent my time with a man engaged in that business. I should know how to put the staves and the hoops if I stayed long enough in the cooper's yard; and I have no doubt that any of you could learn anything you desired provided you had sufficient time and opportunity. So, if you search for illustrations, you will learn to make them for yourselves.

That brings me to my last point. I began this lecture by warning you against the practice of making anecdotes; I close it by advising you often to set yourself the task of making illustrations. Try to make comparisons from the things round about you. I think it would be well, sometimes, to shut the door of your study, and say to yourself, "I will not go out of this room until I have made at least half a dozen good illustrations." The Chinese say that the intellect lies in the stomach, and that the affections are there too. I think they are right on the latter point, because, you know, if you are ever very fond of anybody—your wife, for instance—you say that you could eat her; and you also say that such and such a person is very sweet. So, too, the intellect may lie in the stomach; and consequently, when you have been shut in for two or three hours, and begin to want your dinner or tea, you may be quickened into the making of the six illustrations I have mentioned as a minimum. Your study would be a veritable prison if you could not make as many useful comparisons as that from the different objects in the room. I should say that a prison itself would furnish suggestions for making many metaphors. I do not wish you to go to prison for that purpose; but if you ever do get there, you ought to be able to learn how to preach in an interesting manner upon such a passage as this—"Bring my soul out of prison;" or this, "He was there in the prison. But the Lord was with Joseph."

If you cannot get your brains to work in the house, you might take a walk, and say to yourself, "I will wander over the fields, or I will get into the garden, or I will stroll in the wood, and see if I cannot find some illustration or other." You might even go and look in at a shop-window, and see if there are not some illustrations to be discovered there. Or you might stand still a little while, and hear what people say as they go by; or stop where there is a little knot of idlers, and try to hear what they are talking about, and see what symbol you can make out of it. You should also spend as much time as you can visiting the sick; that will be a most profitable thing to do, for in that sacred service you will have many opportunities of getting illustrations from the tried children of God as you hear their varied experiences. It is wonderful what pages of a new cyclopedia of illustrative teaching you might find written out with indelible ink if you went visiting the sick, or even in talking with children. Many of them will say things that you will be able to quote with good effect in your sermons. At any rate, do make up your mind that you will attract and interest the people by the way in which you set the gospel before them. Half the battle lies in making the attempt, in coming to this determined resolution, "God helping me, I will teach the people by parables, by similes, by illustrations, by anything that will be helpful to them; and I will seek to be a thoroughly interesting preacher of the Word."

I earnestly hope you will practise the art of making illustrations. I will try to prepare a little set of exercises for you to do week by week. I shall give you some subject and some object, between which there is a likeness; and I shall get you to try to see the resemblance, and to find out what comparisons can be instituted between them. I shall also, if I can, give you some subject without an object, and then say to you, "Illustrate that; tell us, for instance, what virtue is like." Or, sometimes, I may give you the object without the subject, thus—"A diamond; how will you use that as an illustration?" Then, sometimes, I may give you neither the subject nor the object, but just say, "Bring me an illustration." I think we might, in this way, make a set of exercises which would be very useful to you all.

The way to get a mind worth having is to get one well stored with things worth keeping. Of course, the man who has the most illustrations in his head will be the one who will use the most illustrations in his discourses. There are some preachers who have the bump of illustration fully developed; they are sure to illustrate their subject, they cannot help it. There are some men who always see "likes"; they catch a comparison long before others see it. If any of you say that you are not good at illustrating, I reply, "My brother, you must try to grow horns if you have not any on your head." You may never be able to develop any vast amount of imagination or fancy if you do not possess it at the first—just as it is hard to make a cheese out of a millstone—but by diligent attention to this matter you may improve upon what you now are. I do believe that some fellows have a depression in their craniums where there ought to be a bump. I knew a young man, who tried hard to get into this college; but he never saw how to join things together unless he tied them by their tails. He brought out a book; and when I read it, I found at once that it was full of my stories and illustrations; that is to say, every illustration or story in the book was one that I had used, but there was not one of them that was related as it ought to have been. This man had so told the story that it was not there at all; the very point which I had brought out he had carefully omitted, and every bit of it was told correctly except the one thing that was the essence of the whole. Of course, I was glad that I did not have that brother in the college; he might have been an ornament to us by his deficiencies, but we can do without such ornaments, indeed, we have had enough of them already.

Finally, dear brethren, do try with all your might to get the power to see a parable, a simile, an illustration, wherever it is to be seen; for to a great extent this is one of the most important qualifications of the man who is to be a public speaker, and especially of the man who is to be an efficient preacher of the gospel of Christ. If the Lord Jesus made such frequent use of parables, it must be right for us to do the same.
