Should Preachers Use Commentaries?

"In order to be able to expound the Scriptures, and as an aid to your pulpit studies, you will need to be familiar with the commentators: a glorious army, let me tell you, whose acquaintance will be your delight and profit. Of course, you are not such wiseacres as to think or say that you can expound Scripture without assistance from the works of divines and learned men who have laboured before you in the field of exposition. If you are of that opinion, pray remain so, for you are not worth the trouble of conversion, and like a little coterie who think with you, would resent the attempt as an insult to your infallibility. It seems odd, that certain men who talk so much of what the Holy Spirit reveals to themselves, should think so little of what he has revealed to others."

-Charles Spurgeon, "Commenting and Commentaries"
