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.
